Unique Name Validation

[kapishsingla]

Hi,

I'm implementing validation to ensure each entity has a unique name across file boundaries. Each file corresponds to a Langium document, and each document contains a single entity.

For Instance,
file1 a.ext -> entity abc{}
file2 b.ext -> entity abc{}

We need to validate that Entity's name should not be same across the different file.

Request to help us with an optimized approach?

Hi,

You can use the IndexManager to retrieve all entities and cache the result in a multimap.
This project might help:

I don't know if there is a more optimized approach.
