Hallo all,

I've created a grammar with XText similar to the grammar of the getting started section of the xtext user manual. In this case it is possible to access entities across different files but I can also define entities with the same name in both files.

Is it possible to check that the name of an entity is unique accross files?.

Thanks and Best Regards
Florian

Hi,

Validation may help you to check that entites name are unique acrros different namespace. Implement a method that check unicity of entities name in your DslJavaVAlidator :

exple :

@Check
	public void checkAttributeNameIsUnique(Attribute aAttribute){
		final String lName = aAttribute.getName();
		for (InterfaceMember sibling:((Interface)aAttribute.eContainer()).getMembers())
		{
			if (sibling instanceof Attribute)
			{
				if (((Attribute) sibling).getName().equals(lName)  &&  sibling != aAttribute)
				{
					error("duplicate name '" + lName +"'", WebIDLPackage.ATTRIBUTE__NAME);
				}
			}
		}
	}
