Interface CloseableVerificationKeyResolver

All Superinterfaces:

AutoCloseable, Closeable, Initable, org.jose4j.keys.resolvers.VerificationKeyResolver

All Known Implementing Classes:

JwksFileVerificationKeyResolver, RefreshingHttpsJwksVerificationKeyResolver

public interface CloseableVerificationKeyResolver
extends Initable, Closeable, org.jose4j.keys.resolvers.VerificationKeyResolver

The OAuthBearerValidatorCallbackHandler uses a VerificationKeyResolver as part of its validation of the incoming JWT. Some of the VerificationKeyResolver implementations use resources like threads, connections, etc. that should be properly closed when no longer needed. Since the VerificationKeyResolver interface itself doesn't define a close method, we provide a means to do that here.
