Interface QueryDirectives

All Known Implementing Classes:

QueryDirectivesImpl

@PublicApi
public interface QueryDirectives

This gives you access to the immediate directives on a MergedField. This does not include directives on parent fields or fragment containers.

Because a MergedField can actually have multiple fields and hence directives on each field instance its possible that there is more than one directive named "foo" on the merged field. How you decide which one to use is up to your code.

NOTE: A future version of the interface will try to add access to the inherited directives from parent fields and fragments. This proved to be a non trivial problem and hence we decide to give access to immediate field directives and provide this holder interface so we can add the other directives in the future
