Class CAstOperator

java.lang.Object
  com.ibm.wala.cast.tree.impl.CAstOperator

All Implemented Interfaces:

CAstNode

public class CAstOperator
extends java.lang.Object
implements CAstNode

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