Class CombinedWiringFactory

java.lang.Object

graphql.schema.idl.CombinedWiringFactory

All Implemented Interfaces:

WiringFactory

@PublicApi
public class CombinedWiringFactory
extends java.lang.Object
implements WiringFactory

This combines a number of WiringFactorys together to act as one. It asks each one whether it handles a type and delegates to the first one to answer yes.
