Enum Constant Details

ENTER

public static final InvocationType ENTER

The probe method will be called before any code of the intercepted method is called. You cannot use ReturnValue or ExceptionValue parameters for methods of this type.

EXIT

public static final InvocationType EXIT

The probe method will be called when the intercepted method exits, either by returning normally or by throwing an exception. You can use both ReturnValue and ExceptionValue parameters for methods of this type. If the intercepted method returns normally, the ExceptionValue parameter will be null. If the method throws an exception, the ReturnValue parameter will be null.

This type cannot be used for constructors.

RETURN

public static final InvocationType RETURN

The probe method will be called when the intercepted method returns normally. You can use a ReturnValue parameter, but no ExceptionValue parameter for methods of this type.

EXCEPTION

public static final InvocationType EXCEPTION

The probe method will be called when the intercepted method throws an exception. You can use an ExceptionValue parameter, but no ReturnValue parameter for methods of this type.

This type cannot be used for constructors.

Method Details

values

public static InvocationType[] values()

Returns:

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

valueOf

public static InvocationType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

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

Returns:

the enum constant with the specified name

Throws:
