Method Detail

execute

public void execute(MethodInfo method,
                    int pos,
                    CodeIterator iter,
                    Frame frame,
                    Subroutine subroutine)
             throws BadBytecode

Execute the instruction, modeling the effects on the specified frame and subroutine. If a subroutine is passed, the access flags will be modified if this instruction accesses the local variable table.

Parameters:

method - the method containing the instruction

pos - the position of the instruction in the method

iter - the code iterator used to find the instruction

frame - the frame to modify to represent the result of the instruction

subroutine - the optional subroutine this instruction belongs to.

Throws:

BadBytecode - if the bytecode violates the jvm spec
