Class CAstOperator

java.lang.Object

com.ibm.wala.cast.tree.impl.CAstOperator

All Implemented Interfaces:

CAstLeafNode, CAstNode

public class CAstOperator
extends Object
implements CAstLeafNode

Various operators that are built in to many languages, and hence perhaps deserve special notice in WALA CAst interface. There is no strong notion of what should be in here, so feel free to add other common operators.
