Class CollectionCredentialResolver

java.lang.Object

org.opensaml.security.credential.impl.AbstractCredentialResolver

org.opensaml.security.credential.impl.AbstractCriteriaFilteringCredentialResolver

org.opensaml.security.credential.impl.CollectionCredentialResolver

All Implemented Interfaces:

Resolver<Credential,CriteriaSet>, CredentialResolver

public class CollectionCredentialResolver
extends AbstractCriteriaFilteringCredentialResolver

An implementation of CredentialResolver that uses a Collection as the underlying credential source.

The credentials returned are filtered based on any EvaluableCredentialCriterion that may have been present in the specified criteria set, or that are resolved by lookup in the EvaluableCredentialCriteriaRegistry.
