A GraphQL API for EMF
summary
A GraphQL API is integrated into Eclipse Sirius to expose EMF and workspace functionality over a single HTTP endpoint using graphql-java and a programmatic schema generator; it supports queries, mutations, cursor-based pagination (a cursor-based pagination relay style), and a simple cost analysis that rejects queries over a 100-point cost limit. Schema maps EMF classes/interfaces to GraphQL types with deliberate field duplication, a WebSocket subscriptions prototype exists, Apollo-style persisted queries and caching are planned, and the endpoint ships with Sirius 6.1 release.
