Method Summary

Modifier and Type	Method	Description
void	injectCompletionFrame(org.objectweb.asm.MethodVisitor methodVisitor)	Injects a frame indicating the completion of the currently handled method, i.e.
void	injectExceptionFrame(org.objectweb.asm.MethodVisitor methodVisitor)	Injects a frame indicating the beginning of an exception handler for the currently handled method.
void	injectReturnFrame(org.objectweb.asm.MethodVisitor methodVisitor)	Injects a frame indicating the beginning of a return value handler for the currently handled method.
void	translateFrame(org.objectweb.asm.MethodVisitor methodVisitor, int type, int localVariableLength, java.lang.Object[] localVariable, int stackSize, java.lang.Object[] stack)	Translates a frame.

Method Detail

translateFrame

void translateFrame(org.objectweb.asm.MethodVisitor methodVisitor,
                    int type,
                    int localVariableLength,
                    java.lang.Object[] localVariable,
                    int stackSize,
                    java.lang.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(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

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

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.
