Enum Constant Details

NEVER

public static final OverwriteMode NEVER

Indicates that if the destination file exists, it won't be replaced in any case.

ALWAYS

public static final OverwriteMode ALWAYS

Indicates that if the destination file exists, it will be replaced in any case.

IF_NEWER

public static final OverwriteMode IF_NEWER

Indicates that if the destination file exists, it will be replaced if the source file is newer. On Windows, the file version resource will be used for the comparison. If the destination file is newer, it will be skipped silently.

IF_NEWER_OTHERWISE_ASK

public static final OverwriteMode IF_NEWER_OTHERWISE_ASK

Indicates that if the destination file exists, it will be replaced if the source file is newer. On Windows, the file version resource will be used for the comparison. If the destination file is newer, the framework will ask the user if the file should be replaced.

ALWAYS_ASK_EXCEPT_FOR_UPDATE

public static final OverwriteMode ALWAYS_ASK_EXCEPT_FOR_UPDATE

Indicates that if the destination file exists and has not been installed by a previous run of the installer, the user will be asked whether to replace the file. Please note that if the user chooses "Never" or "Always", the framework won't ask the user again.

ALWAYS_ASK

public static final OverwriteMode ALWAYS_ASK

Indicates that the user will be asked whether to replace the file even if it was installed by a previous run of the installer. Please note that if the user chooses "Never" or "Always", the framework won't ask the user again.

Method Details

values

public static OverwriteMode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static OverwriteMode valueOf(String name)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getFromIntValue

public static OverwriteMode getFromIntValue(int overwrite)

Convert int value to constant.

Parameters:

overwrite - the int value

Returns:

the constant

getIntValue

public int getIntValue()

Convert to an int value.

Returns:

the int value

toString

public String toString()

Overrides:

toString in class Enum<OverwriteMode>
