Class AbstractChainingCredentialResolver<ResolverType extends CredentialResolver>

java.lang.Object

org.opensaml.security.credential.impl.AbstractCredentialResolver

org.opensaml.security.credential.impl.AbstractChainingCredentialResolver<ResolverType>

Type Parameters:

ResolverType - the subtype of CredentialResolver to be chained

All Implemented Interfaces:

Resolver<Credential,CriteriaSet>, CredentialResolver

Direct Known Subclasses:

ChainingCredentialResolver, ChainingKeyInfoCredentialResolver

public abstract class AbstractChainingCredentialResolver<ResolverType extends CredentialResolver>
extends AbstractCredentialResolver

An abstract implementation of CredentialResolver which chains together one or more underlying credential resolver implementations. Resolved credentials are returned from all underlying resolvers in the chain, in the order implied by the order of the resolvers in the chain.
