gw.internal.gosu.parser.statements

Class SwitchStatement

java.lang.Object

gw.internal.gosu.parser.ParsedElement

gw.internal.gosu.parser.Statement

gw.internal.gosu.parser.statements.SwitchStatement

All Implemented Interfaces:

IParsedElement, IStatement, ISwitchStatement

public final class SwitchStatement
extends Statement
implements ISwitchStatement

Represents a switch-statement as specified in the Gosu grammar:

 switch-statement
   switch (<expression>) { [switch-cases] [switch-default] }
 

 switch-cases
   <switch-case>
   <switch-cases> <switch-case>
 

 switch-case
   case <expression> : [statement-list]
 

 switch-default
   default : [statement-list]
