Enum Constant Detail

CLASS

public static final Weaver.TargetSource CLASS

The class is the target object.

FIRST_PARAMETER

public static final Weaver.TargetSource FIRST_PARAMETER

The first parameter is the target object. For non-static methods, the first parameter is this.

SECOND_PARAMETER

public static final Weaver.TargetSource SECOND_PARAMETER

The second parameter is the target object. For non-static methods, the first parameter is this.

THIRD_PARAMETER

public static final Weaver.TargetSource THIRD_PARAMETER

The third parameter is the target object. For non-static methods, the first parameter is this.

Method Detail

values

public static Weaver.TargetSource[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Weaver.TargetSource c : Weaver.TargetSource.values())
    System.out.println(c);

Returns:

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

valueOf

public static Weaver.TargetSource valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

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

NullPointerException - if the argument is null

canApply

public boolean canApply(Method method)

Whether this target source can be used to instrument a given method.

Parameters:

method - The method to test.

Returns:

true if the source can be used.
