Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
protected static class	AccessControllerPlugin.Initializer.WithoutProperty	An initializer that always uses the access controller if it is available.
protected static class	AccessControllerPlugin.Initializer.WithProperty	An initializer that uses a property to determine if the access controller should be actually used even if it is available.

Constructor Detail

Initializer

protected Initializer(TypeDescription instrumentedType,
                      java.lang.String name)

Creates a new initializer.

Parameters:

instrumentedType - The instrumented type.

name - The name of the field to determine the use of access controller dispatch.

Method Detail

apply

public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                   Implementation.Context implementationContext,
                                   MethodDescription instrumentedMethod)

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

Parameters:

methodVisitor - The method visitor to which the byte code appender writes its code to.

implementationContext - The implementation context of the current type creation process.

instrumentedMethod - The method that is the target of the instrumentation.

Returns:

The required size for the applied byte code to run.

onAccessController

protected abstract int onAccessController(org.objectweb.asm.MethodVisitor methodVisitor)

Invoked to determine if the access controller should be used after the class was found.

Parameters:

methodVisitor - The method visitor to dispatch to.

Returns:

The size of the stack required to implement the implemented dispatch.
