Package com.install4j.api.context

Interface Context

All Known Subinterfaces:
InstallerContext, UninstallerContext
public interface Context
Base class for installation and uninstallation context. The actual context passed to screens, actions and form components is either an InstallerContext or an UninstallerContext, depending on whether they are part of the installer or uninstaller.

  • Method Details

    • getLanguageId

      String getLanguageId()
      Return the ISO code for the language that the installer is running with. If only the principal language has been configured for the installer, this will always be the code for the principal language. If additional languages have been configured, the user can select a language or the language has been automatically determined by the installer, depending on the settings on the "Languages" tab in the install4j GUI. If the installer chooses a language automatically and none of the additional languages matches the system locale, the principal language will be used.
      Returns:
      the ISO code for the language. This code is displayed in brackets after the language name in the install4j GUI.

    • getMessage

      String getMessage(String key) throws MissingResourceException
      Get a message for a localization key. This method is equivalent to getMessage(String, Object[]) with the arguments parameter set to null.
      Parameters:
      key - the localization key
      Returns:
      the message
      Throws:
      MissingResourceException - if the key cannot be found
      See Also:

    • getMessage

      String getMessage(String key, Object... arguments) throws MissingResourceException
      Get a message for a localization key. The key can be either a system key as present in the resource/messages/messages_*.utf8 files or a key in a custom localization file.

      The search order is

      • custom localization file for actual language
      • custom localization file for principal language
      • system localization file provided by install4j

      The message is passed to 

      
 java.text.MessageFormat.format(message, arguments)
      which replaces variables of the form {0} that are embedded in the message key.
      Parameters:
      key - the localization key
      arguments - the arguments as processed by the java.text.MessageFormat class. Can be null.
      Returns:
      the message
      Throws:
      MissingResourceException - if the key cannot be found

    • getInstallationDirectory

      File getInstallationDirectory()
      Retrieves the installation directory selected by the user, or the default installation directory if the user has not yet made a selection. Note that on macOS this is usually /Applications. If you delete this directory, it will have catastrophic consequences on macOS. To get the directory where files are installed in a cross-platform way, please use getContentDirectory() instead.
      Returns:
      the installation directory

    • getDefaultInstallationDirectory

      File getDefaultInstallationDirectory()
      Retrieves the default installation directory configured in the install4j IDE. If "Detect previous installation directory" is selected on the "Installer->Update options" tab, the value returned by getInstallationDirectory() may not be the same as the one configured in the install4j IDE. If you need to fall back to the default directory for some reason, you can use the return value of this method and call InstallerContext.setInstallationDirectory(File).
      Returns:
      the default installation directory as configured in the install4j IDE

    • getContentDirectory

      File getContentDirectory()
      Retrieves the directory mapped to the "Installation directory" in the distribution tree. On Windows, Linux and Unix, this is the same as getInstallationDirectory(). For single bundle archives on macOS, this is [Bundle name].app/Contents/Resources/app/. To reference an installed file in a cross-platform way, use this method and not getInstallationDirectory().
      Returns:
      the installation directory

    • getResourceDirectory

      File getResourceDirectory()
      Retrieves the directory where the resource files are present that have been configured on the Installer->Custom Code &Resources tab.
      Returns:
      the resources directory

      the LauncherSetup or null if the ID doesn't exist.
      See Also:

    • isCancelling

      boolean isCancelling()
      Returns whether the user has canceled the installation or not. Long-running actions should check this method frequently to comply with a cancel request from the user.
      Returns:
      true or false.

    • cancel

      void cancel()
      Cancel the installer application without asking any questions. Rollback of already executed actions will be performed.

      If a question has to be asked first, use runWithSuspendedActions(Runnable) and call this method from the Runnable.

    • runWithSuspendedActions

      void runWithSuspendedActions(Runnable runnable)
      Execute some code while any running actions are suspended. Actions are only suspended when they check whether the installer is being canceled, so the currently executing action may not be suspended immediately. It makes sense to call this method as a reaction to an external event, such as a click on a button. For example, you can then ask the user whether the installer application should be canceled and if yes, call cancel() in the Runnable.
      Parameters:
      runnable - the code that will be executed while the actions are suspended

    • handleCriticalException

      void handleCriticalException(Throwable e)
      If you encounter an exception in your code that cannot be handled, you can use this method to invoke the default exception handling of the install4j runtime. An error report will be prepared, the user will be notified, and the installer or uninstaller will quit. No rollback will be performed.

      This method is for exceptional circumstances only. Do not call this method if an action fails in an expected way: if you return false from an action, its configurable failure strategy can be used to inform the user of the failure and rollback previous actions.

      Parameters:
      e - the exception
      See Also:

    • getDestinationFile

      File getDestinationFile(File archiveFile)
      Get the location where the installer will install a file in the distribution tree. This method is important for actions with properties of type java.io.File. The property values will be relative file names and contain encoded information about installation roots. With this method, the installation location can be resolved. Note that the result of this method can change over time as installer variables or the installation directory are changed.
      Parameters:
      archiveFile - the relative file in the distribution tree
      Returns:
      the location of the installed file

    • getDestinationFile

      File getDestinationFile(String archivePath)
      Same as getDestinationFile, only with a path argument.
      Parameters:
      archivePath - the relative path in the distribution tree
      Returns:
      the location of the installed file
      See Also:

    • getDestinationFileInfo

      FileInfo getDestinationFileInfo(String archivePath)
      Analyze a path in the distribution tree. Beans with java.io.File properties can use this method to split paths into root information and relative information and to resolve the installation location of a file in the distribution tree. The getDestinationFile(..) methods directly give you the installed file location.
      Parameters:
      archivePath - the relative path in the distribution tree
      Returns:
      the FileInfo information object
      See Also:

    • getVariable

Compiler variables are defined on the "Compiler variables" tab and can be overridden for each media file. System compiler variables are also available from this method. In the install4j IDE, compiler variables are written as ${compiler:variableName}. Please read the help topic on variables in the documentation for more information.
      Parameters:
      variableName - the name of the compiler variable. Do not use the IDE syntax ${compiler:...} for this parameter.
      Returns:
      the variable value or null if the variable with the specified name was not defined.

    • runScript

      Object runScript(ScriptProperty scriptProperty, Bean bean, Object... parameters) throws Exception
      Run a script. Beans that have properties of type com.install4j.api.beans.ScriptProperty can run these user-defined scripts at runtime with this method. Script properties require a property descriptor in the associated BeanInfo class that contains information about the return type as well as any additional parameters.
      Parameters:
      scriptProperty - the value of the script property
      bean - the bean that defines the script property
      parameters - the additional parameters

      See Also:

    • getProgressInterface

      ProgressInterface getProgressInterface()
      Get the current progress interface. If called by a screen or form component, this will be a default progress interface where status messages and progress methods do nothing. A screen can replace that default progress interface with a different implementation so that the status messages and progress methods invoked by the associated actions are displayed on the screen. This is done by the "Installation" screen and the customizable "Display progress" screen.

      During rollback, a special rollback dialog will be shown and make its progress interface available through this method.

      Returns:
      the current progress interface
      See Also:

    • goForward

      void goForward(int numberOfScreens, boolean checkCondition, boolean executeActions) throws NotSupportedInElevationException
      Go forward in the screen sequence.

      Note: This method only has a direct effect when called from a screen. When called from an action, all remaining actions for the screen will be executed, and the most recent request for a screen change will then be performed.

      Parameters:
      numberOfScreens - the number of screens to move forward. If the resulting index is beyond the last screen, the installer or uninstaller will quit.
      checkCondition - if the "Condition expression" of the target screen should be checked or not
      executeActions - if the associated actions of the current screen should be performed or not. This parameter has no effect if this method is called from an action.
      Throws:
      NotSupportedInElevationException - if this method is called by an elevated action

    • goBack

      void goBack(int numberOfScreens) throws NotSupportedInElevationException
      Go backwards in the screen sequence. This is the sequence displayed on the "Screens" tab in the install4j GUI. You can go backwards in the screen history with the goBackInHistory method.

      Note: This method only has a direct effect when called from a screen. When called from an action, all remaining actions for the screen will be executed, and the most recent request for a screen change will then be performed.

      Parameters:
      numberOfScreens - the number of screens to move backwards. If the resulting index is negative, a RuntimeException will be thrown. You can pass 0 to return to the current screen from an action.
      Throws:
      NotSupportedInElevationException - if this method is called by an elevated action
      See Also:

    • goBackInHistory

      void goBackInHistory(int numberOfScreens) throws NotSupportedInElevationException
      Go backwards in the screen history. This is not necessarily the same as the screen sequence, since the screen flow can be changed programmatically.

      Note: This method only has a direct effect when called from a screen. When called from an action, all remaining actions for the screen will be executed, and the most recent request for a screen change will then be performed.

      Parameters:
      numberOfScreens - the number of screens to move backwards in the screen history. If the resulting index is negative, a RuntimeException will be thrown. You can pass 0 to return to the current screen from an action.
      Throws:
      NotSupportedInElevationException - if this method is called by an elevated action
      See Also:

    • goBackInHistory

      void goBackInHistory(Screen targetScreen) throws NotSupportedInElevationException
      Go backwards in the screen history to the target screen. If the given screen has not been registered or was not displayed previously, the operation will fail. Registered screens can be obtained from the getScreenById(...), getScreens(...) and getFirstScreen(...) methods.

      Note: This method only has a direct effect when called from a screen. When called from an action, all remaining actions for the screen will be executed, and the most recent request for a screen change will then be performed.

      Parameters:
      targetScreen - the screen to be activated.
      Throws:
      NotSupportedInElevationException - if this method is called by an elevated action
      See Also:

    • getExternalFile

      File getExternalFile(ExternalFile externalFile, boolean installedLocation)
      Get the location of an external file that was packaged with the installer. Beans that define properties of type ExternalFile can access those files at runtime. When the installer is started, an external file is located in a temporary directory. After the "Install files" action has run, the external file is also copied to the .install4j directory in the installation directory.
      Parameters:
      externalFile - the value of the ExternalFile property
      installedLocation - if true, this method returns the location in the .install4j directory, otherwise the location in the temporary directory is returned. If called in an uninstaller, this argument has no effect and the location in the .install4j directory will always be returned.
      Returns:
      the resolved external file

    • getExternalFile

      File getExternalFile(LocalizedExternalFile localizedExternalFile, boolean installedLocation)
      Get the location of a localized external file that was packaged with the installer. This will return file for the selected language as given by getLanguageId(). If no suitable localization exists, the file for the principal language is returned. The remaining behavior of this method is identical to getExternalFile(ExternalFile, boolean).
      Parameters:
      localizedExternalFile - the value of the LocalizedExternalFile property
      installedLocation - if true, this method returns the location in the .install4j directory, otherwise the location in the temporary directory is returned. If called in an uninstaller, this argument has no effect and the location in the .install4j directory will always be returned.
      Returns:
      the resolved external file

    • isErrorOccurred

      boolean isErrorOccurred()
      Determine if an error has occurred for any of the previous actions. After an action fails, this method returns true. If the failure strategy of the failed action is configured in such a way that the execution of the installer continues, you might want to react to the error in a subsequent action.

      Note: This error flag is never cleared. You have to clear it manually with the setErrorOccurred method. If you want to make sure that the error originates in a certain range of actions, you have to add a "Run script" action just before that range and call context.setErrorOccurred(false) in order to clear any earlier error.

      Returns:
      if an error has occurred or not
      See Also:

    • setErrorOccurred

      void setErrorOccurred(boolean errorOccurred)

      void registerResponseFileVariable(String variableName)
      Register a variable that should be written to the response file when the installation is finished. Variables to which form components are bound are automatically registered as response file variables. Only strings, primitive wrappers, as well as string arrays, int arrays and java.util.Date values can be encoded in the response file.
      Parameters:
      variableName - the variable name

    • unregisterResponseFileVariable

      void unregisterResponseFileVariable(String variableName)
      Reverses the action of registerResponseFileVariable(String). This also works for system installer variables that are written to the response file
      Parameters:
      variableName - the variable name

    • registerResponseFileComment

      void registerResponseFileComment(String variableName, String comment)
      Register a comment for a variable that is written to the response file. The comment can be a multi-line string. If non-empty lines do not start with a # character, the # character is prepended. Compiler variables, installer variables, and i18n variables are replaced in the comment string.
      Parameters:
      variableName - the variable name
      comment - the comment. Setting a comment to null, removes the comment.

      exitCode - the exit code.

    • hasBeenElevated

      boolean hasBeenElevated()
      Returns if the code is running in the elevated helper process started by the "Request privileges" action. In this case the code has full privileges, but it can interact with the GUI is a limited way, and some methods in this context will throw a NotSupportedInElevationException.
      Returns:
      true if elevated

    • runElevated

      Serializable runElevated(RemoteCallable remoteCallable, boolean alwaysExecute)
      Execute an remoteCallable with full admin rights if possible.

      If the current process has full admin rights, the remoteCallable is executed in-process. Otherwise, if a 'require admin user' action and macOS or Windows Vista and higher has spawned a helper process with full rights, it is executed by this process.

      Note: Do not interact with the GUI or call methods like Util.showMessage(String) in the code.

      Parameters:
      remoteCallable - the remoteCallable to execute
      alwaysExecute - also execute the remoteCallable if it cannot be executed with full admin rights.
      Returns:
      the object returned by RemoteCallable.execute()

    • runUnelevated

      Serializable runUnelevated(RemoteCallable remoteCallable)
      Execute an remoteCallable with the rights of the original user that started the installer.

      If no elevation has been done by the 'require admin user' action, the remoteCallable is executed in-process. Otherwise, it is executed by the original process.

      Note: Do not interact with the GUI or call methods like Util.showMessage(String) in the code.

      Parameters:
      remoteCallable - the remoteCallable to execute
      Returns:
      the object returned by RemoteCallable.execute()

    • initializeLazilyCreatedScreens

      void initializeLazilyCreatedScreens()
      Initialize all lazily created screens. Screens provided by install4j are not created lazily, so this method only has an effect, if you have custom screens that return true from Screen.isCreateLazily().

    • addToClassPath

      void addToClassPath(File file)
      Add a JAR file or a classpath directory root to the classpath of the installer application. This method if useful if you have lazily created custom screens in your project and you have to add installed JAR files to the classpath before the Screen.createComponent() is called.
      Parameters:
      file - the JAR file or the classpath directory root
