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

All Implemented Interfaces:

CAstNode
```
public class CAstOperator
extends Object
implements CAstNode
```
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.
