Xtext: Cross-Referenzce + JvmTypeReference [message #876866]

I want ot extend from Entity and JvmTypeReference. So the content assist should provide entries for each JvmTypeReference but also for defined entities that have not been compiled to java code yet.

Entity:
	'entity' name=ID ('extends' superType=([Entity] | JvmTypeReference))? '{'
	features+=Feature*
	'}'
	;

Referring to org.eclipse.xtext.example.domainmodel.Domainmodel.

Is there a way to do so?

Hi,

there is this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=350823
the only way i know is to introduce a extra keyword

Entity:
'entity' name=ID ( ('extends' superType=[Entity]) | ('extendsjava' JvmTypeReference))? '{'
features+=Feature*
'}'
;

Hey, I have similar question:

Is it possible to reference types combining Cross-Reference and JvmTypeReference?
e.g. : type=([Entity] | JvmTypeReference)

So far I am not able to make it work. It doesn't recognize the JvmTypeReference types.

Is there a workaround for that or it is entirely impossible?

hi,

what about introducing a prefex e.g.

("/" type=[Entity]) | jvmType=JvmTypeReference)
