Constructor Detail

ExceptionTableSensitiveMethodVisitor

protected ExceptionTableSensitiveMethodVisitor(int api,
                                               MethodVisitor methodVisitor)

Creates an exception table sensitive method visitor.

Parameters:

api - The ASM API version.

methodVisitor - The delegating method visitor.

Method Detail

onAfterExceptionTable

protected abstract void onAfterExceptionTable()

Invoked after the exception table was visited. Typically, the exception table is visited by ASM at the beginning of a method. It is however possible that a user adds exception table entries at a later point. Normally, this is however not meaningful use of ASM.

                             int localVariableLength,
                             Object[] localVariable,
                             int stackSize,

                            int stackSize,
                            Object[] stack)
