extends Object

  • Constructor Details

  • Method Details

    • getStackLength

      public int getStackLength()

    • popDownTo

      public void popDownTo​(int elements)

    • castToBool

      public void castToBool​(int mark, boolean emptyDefault)
      ensure last marked parameter on the stack is a primitive boolean if mark==stack size, we assume an empty expression or statement. was used and we will use the value given in emptyDefault as boolean if mark==stack.size()-1 the top element will be cast to boolean using Groovy truth. In other cases we throw a GroovyBugError

    • pop

      public void pop()
      remove operand stack top element using bytecode pop

    • jump

      public org.objectweb.asm.Label jump​(int ifIns)

    • jump

      public void jump​(int ifIns, org.objectweb.asm.Label label)

    • dup

      public void dup()
      duplicate top element

    • box

      public ClassNode box()

    • remove

      public void remove​(int amount)
      Remove amount elements from the operand stack, without using pop. For example after a method invocation

    • push

      public void push​(ClassNode type)
      push operand on stack

    • swap

      public void swap()
      swap two top level operands

    • replace

      public void replace​(ClassNode type)
      replace top level element with new element of given type

    • replace

      public void replace​(ClassNode type, int n)
      replace n top level elements with new element of given type

    • doGroovyCast

      public void doGroovyCast​(ClassNode targetType)
      do Groovy cast for top level element
