                        int padding)

Creates a code translation visitor for translating exit advice.

Parameters:

methodVisitor - A method visitor for writing the instrumented method's byte code.

implementationContext - The implementation context to use.

methodSizeHandler - A handler for computing the method size requirements.

stackMapFrameHandler - A handler for translating and injecting stack map frames.

instrumentedMethod - The instrumented method.

adviceMethod - The advice method.

offsetMappings - A mapping of offsets to resolved target offsets in the instrumented method.

suppressionHandler - The suppression handler to use.

padding - The padding after the instrumented method's arguments in the local variable array.
