WithPreservedArguments

protected WithPreservedArguments(TypeDescription instrumentedType,
                                 MethodDescription instrumentedMethod,
                                 List<? extends TypeDescription> initialTypes,
                                 List<? extends TypeDescription> preMethodTypes,

                                 boolean expandFrames)

Creates a new stack map frame handler that requires the stack map frames of the original arguments to be preserved.

Parameters:

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

initialTypes - A list of virtual method arguments that are explicitly added before any code execution.

preMethodTypes - A list of virtual method arguments that are available before the instrumented method is executed.

postMethodTypes - A list of virtual method arguments that are available after the instrumented method has completed.

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

Method Detail

bindExit

public Advice.StackMapFrameHandler.ForAdvice bindExit(MethodDescription.InDefinedShape adviceMethod)

Binds this meta data handler for the exit advice.

Parameters:

adviceMethod - The exit advice method.

Returns:

An appropriate meta data handler for the enter method.

injectReturnFrame

public void injectReturnFrame(org.objectweb.asm.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(org.objectweb.asm.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(org.objectweb.asm.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(org.objectweb.asm.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(org.objectweb.asm.MethodVisitor methodVisitor)

Injects a frame after initialization if any initialization is performed.

Parameters:

methodVisitor - The method visitor to write any frames to.
