Class GraphQLContext

java.lang.Object

graphql.GraphQLContext

@PublicApi
 @ThreadSafe
public class GraphQLContext
extends java.lang.Object

This context object can be used to contain key values that can be useful as "context" when executing DataFetchers

 
     DataFetcher df = new DataFetcher() {
        public Object get(DataFetchingEnvironment env) {
            GraphQLContext ctx = env.getContext()
            User currentUser = ctx.getOrDefault("userKey",new AnonymousUser())
            ...
        }
     }
 
 

You can set this up via ExecutionInput.Builder.context(graphql.GraphQLContext.Builder)
