Constructor Detail

DoWhileLoop

public DoWhileLoop(Tree tree,
                   int scope,
                   Node parent,
                   LoopBlock loopBlock,
                   List<InstructionHandle> instructions)

Creates a new DoWhileLoop 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)

loopBlock - a JODE object representing the do-while loop

instructions - the list of instructions in the loop's method (the whole method, not just the loop)

Method Detail

getFirstInstruction

protected InstructionHandle getFirstInstruction()

Overrides:

getFirstInstruction in class Node

setBody

public void setBody(Node body)

Sets the body of the loop. This may be necessary if, for example, the loop body is determined to be empty and needs to be "fixed up" accordingly.

Overrides:

setBody in class Loop

Parameters:

body - a control flow node representing the loop's body

toString

public String toString()

Converts the do-while loop to a string.

Overrides:

toString in class Object

Returns:

a source-code-like string representing the do-while loop
