Constructor Detail

Initializer

protected Initializer(TypeDescription instrumentedType,
                      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(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(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.
