Class SwitchStatement

java.lang.Object

gw.internal.gosu.parser.ParsedElement

gw.internal.gosu.parser.Statement

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]
