How to leverage ecore in Xtext [message #835501]

Hi, all,

In the Terminal Grammar file, I see the following declarations:

import "http: //www.eclipse.org/emf/2002/Ecore" as ecore
...
terminal INT returns ecore::EInt: ('0'..'9')+;

So, the questions here are how to leverage the ecore for other datatypes, e.g., long, date, and where can I find the content of the ecore (if has) so as to leverage other information?

Thanks.
Robin

Hi,

the very same as with EInt. the only extra thing you need is a value converter http://www.eclipse.org/Xtext/documentation/2_1_0/090-valueconverter.php

But, how can I know what datatypes are there in ecore to be reused?

Thanks.

Hi

- open Ecore.ecore with a model editor
- show the type hierarchy of EDataType
- buy the EMF book
