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")

nodeFor

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

Creates a Node object reference given an 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.

nodeFor

inline fun <T : NodeObject> ResolverExecutionContext<*>.nodeFor(localId: String): T

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

query

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

Loads the provided selections on the root Query type, and returns the response typed as Q. This is a convenience method that combines selectionsFor and query.

selectionsFor

abstract fun <T : CompositeOutput> selectionsFor(type: Type<T>, selections: String, variables: Map<String, Any?> = emptyMap()): SelectionSet<T>

Creates a SelectionSet on a provided type from the provided Selections String
