Class Goto

java.lang.Object
  edu.uci.eecs.doc.cascade.controlflow.Node
      edu.uci.eecs.doc.cascade.controlflow.Goto

All Implemented Interfaces:

Iterable<Node>

public class Goto
extends Node

Represents goto instructions in a control flow tree. It is a "pseudo-node" because unlike other nodes, it does not represent an element of the source code. It is provided for clients of Cascade that require knowledge of goto instructions for timing analysis and other purposes.

Goto

public Goto(Tree tree,
            int scope,
            Node parent,
            InstructionHandle gotoInstruction)

Creates a new Goto object.

Parameters:

tree - the control flow tree to which this node belongs

scope - the lexical scope of the node (0 = top-level scope)

parent - the node's parent (null if the node has no parent)

gotoInstruction - a BCEL object representing the goto instruction

Method Detail

getInstructions

public List<InstructionHandle> getInstructions()

Overrides:

getInstructions in class Node

Returns:

a list of bytecode instructions

toString

public String toString()

Converts the goto node to a string.

Overrides:

toString in class Object

Returns:
