[xcore] enum in switch statement [message #896768]

Hi

defining a operation in xcore brings me to the point to have a switch statement using a enum
property. But i can't figure out how to code the case:

Example:

enum EditType
{
PROJECT_FILE = 0
DATABASE = 1
}

class A
{
EditType editType
op void doSomeThing(){
switch(editType){
case DATABASE: //getting an ERROR
case 1: //this is OK but not nice
}
}
}

How do I specify the specific switch case?

Martin,

You use it like this:

op void doSomeThing(){
switch(editType){
case EditType::PROJECT_FILE:
{

}
case EditType::DATABASE:
{

}
}
}

I.e., the Xbase syntax for referring to static fields uses "::" not
".". It would be nice if Xbase made the enumerator's visible without
qualification in the switch. Maybe you could open a bugzilla
enhancement against Xtext's Xbase. Please post the bugzilla number here.
