Constructor Detail

Trivial

protected Trivial(TypeDescription instrumentedType,
                  MethodDescription instrumentedMethod,
                  List<? extends TypeDescription> latentTypes,
                  boolean expandFrames)

Creates a new stack map frame handler that applies a trivial translation for the instrumented method's stack map frames.

Parameters:

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

latentTypes - A list of virtual arguments that are available after the enter advice method is executed.

expandFrames - true if the meta data handler is expected to expand its frames.

Method Detail

translateFrame

public void translateFrame(MethodVisitor methodVisitor,
                           int type,
                           int localVariableLength,
                           @MaybeNull
                           Object[] localVariable,
                           int stackSize,
                           @MaybeNull
                           Object[] stack)

Translates a frame.

Parameters:

methodVisitor - The method visitor to write the frame to.

type - The frame's type.

localVariableLength - The local variable length.

localVariable - An array containing the types of the current local variables.

stackSize - The size of the operand stack.

stack - An array containing the types of the current operand stack.

bindExit

public Advice.StackMapFrameHandler.ForAdvice bindExit(MethodDescription.TypeToken typeToken)

Binds this metadata handler for the exit advice.

Parameters:

typeToken - The type token representing the advice method.

Returns:

An appropriate metadata handler for the enter method.

injectReturnFrame

public void injectReturnFrame(MethodVisitor methodVisitor)

Injects a frame indicating the beginning of a return value handler for the currently handled method.

Parameters:

methodVisitor - The method visitor onto which to apply the stack map frame.

injectExceptionFrame

public void injectExceptionFrame(MethodVisitor methodVisitor)

Injects a frame indicating the beginning of an exception handler for the currently handled method.

Parameters:

methodVisitor - The method visitor onto which to apply the stack map frame.

injectCompletionFrame

public void injectCompletionFrame(MethodVisitor methodVisitor)

Injects a frame indicating the completion of the currently handled method, i.e. all yielded types were added.

Parameters:

methodVisitor - The method visitor onto which to apply the stack map frame.

injectPostCompletionFrame

public void injectPostCompletionFrame(MethodVisitor methodVisitor)

Injects a frame indicating the completion of the currently handled method, i.e. all yielded types were added.

Parameters:

methodVisitor - The method visitor onto which to apply the stack map frame.

injectInitializationFrame

public void injectInitializationFrame(MethodVisitor methodVisitor)

Injects a frame after initialization if any initialization is performed.

Parameters:

methodVisitor - The method visitor to write any frames to.

injectStartFrame

public void injectStartFrame(MethodVisitor methodVisitor)

Injects a frame before executing the instrumented method.

Parameters:

methodVisitor - The method visitor to write any frames to.
