Method Summary

Modifier and Type	Method and Description
void	injectCompletionFrame(MethodVisitor methodVisitor, boolean secondary) Injects a frame indicating the completion of the currently handled method, i.e. all yielded types were added.
void	injectExceptionFrame(MethodVisitor methodVisitor) Injects a frame indicating the beginning of an exception handler for the currently handled method.
void	injectReturnFrame(MethodVisitor methodVisitor) Injects a frame indicating the beginning of a return value handler for the currently handled method.
void	translateFrame(MethodVisitor methodVisitor, int type, int localVariableLength, Object[] localVariable, int stackSize, Object[] stack) Translates a frame.

Method Detail

translateFrame

void translateFrame(MethodVisitor methodVisitor,
                    int type,
                    int localVariableLength,
                    Object[] localVariable,
                    int stackSize,
                    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.

injectReturnFrame

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

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

void injectCompletionFrame(MethodVisitor methodVisitor,
                           boolean secondary)

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.

secondary - true if another completion frame for this method was written previously.
