WithoutArgumentCopy

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

                              boolean allowCompactCompletionFrame)

Creates a new stack map frame handler that expects the original frames 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.

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

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.

allowCompactCompletionFrame - true if a completion frame for the method bust be a full frame to reflect an initialization change.

Method Detail

injectStartFrame

public void injectStartFrame(MethodVisitor methodVisitor)

Injects a frame before executing the instrumented method.

Parameters:

methodVisitor - The method visitor to write any frames to.

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.
