Interface IJavaSwitch

All Superinterfaces:
IJavaCompound, IJavaElement, IJavaExpression, IJavaStatement
@Ser public interface IJavaSwitch extends IJavaCompound
Java AST interface to represent switch statements. They support integer keys (standard switch), String keys, and Enum keys. Limitation: These objects do not support case-block replacement.

A switch-statement consists of an expression, zero or more cases and an optional default case.

Example: 

 switch(exp)
   case c0: b0
   case c1: b1
   default: b2
