Method Detail

translateFrame

void translateFrame(MethodVisitor methodVisitor,
                    int frameType,
                    int localVariableLength,
                    Object[] localVariable,
                    int stackSize,
                    Object[] stack)

Translates a frame.

Parameters:

methodVisitor - The method visitor to write the frame to.

frameType - 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.

injectHandlerFrame

void injectHandlerFrame(MethodVisitor methodVisitor)

Injects a frame for a method's exception handler.

Parameters:

methodVisitor - The method visitor to write the frame to.

injectCompletionFrame

void injectCompletionFrame(MethodVisitor methodVisitor,
                           boolean secondary)

Injects a frame after a method's completion.

Parameters:

methodVisitor - The method visitor to write the frame to.

secondary - true if the frame is written a second time.
