                                                                 org.apache.bcel.generic.Type type,

        Allocates a local variable. If the slot allocator has already been initialized, then call addLocalVariable2() so that the new variable is known to the allocator. Failing to do this may cause the allocator to return a slot that is already in use.

        Breaks up the IL for this MethodGenerator into separate outlined methods so that no method exceeds the 64KB limit on the length of the byte code associated with a method.
        Parameters:
        classGen - The ClassGen with which the generated methods will be associated
        originalMethodSize - The number of bytes of bytecode represented by the InstructionList of this method
        Returns:
        an array of the outlined Methods and the original method itself

      • markChunkStart

        public void markChunkStart()
        Mark the end of the method's InstructionList as the start of an outlineable chunk of code. The outlineable chunk begins after the InstructionHandle that is at the end of the method's InstructionList, or at the start of the method if the InstructionList is empty. See OutlineableChunkStart for more information.

      • markChunkEnd

        public void markChunkEnd()
        Mark the end of an outlineable chunk of code. See OutlineableChunkStart for more information.
