A generic context for resolving fields or types

Functions

globalIDStringFor

abstract fun <T : NodeObject> globalIDStringFor(type: Type<T>, internalID: String): String

Creates a GlobalID and returns it as a String. Example usage: globalIDStringFor(User.Reflection, "123")

query

abstract suspend fun query(operation: QueryFromAnnotation, variables: Map<String, Any?> = emptyMap()): Q

Loads the operation declared by a @GraphQLOperation query object on the root Query type, and returns the response typed as Q.

ref

abstract fun <T : Object> ref(call: RootFieldCall<T>): T

Creates a lazy reference to a root field that will be later resolved by the engine.

abstract fun <T : NodeObject> ref(id: GlobalID<T>): T

Creates a lazy reference given a Node ID. Only the ID field is accessible from the created reference. Attempting to access other fields will result in an exception. This can be used to construct resolver responses for fields with Node types.

ref

inline fun <T : NodeObject> ResolverExecutionContext<*>.ref(localNodeId: String): T

Creates a Node object reference given a Local ID String representation.
