public abstract class AbstractCriteriaFilteringCredentialResolver
extends AbstractCredentialResolver

An abstract implementation of CredentialResolver that filters the returned Credentials based on the instances of Predicate which are present in the set of criteria as instances of EvaluableCredentialCriterion, or which are obtained via lookup in the EvaluableCredentialCriteriaRegistry.

Method Detail

resolve

@Nonnull
public Iterable<Credential> resolve(@Nullable
                                    CriteriaSet criteriaSet)
                             throws ResolverException

Specified by:

resolve in interface Resolver<Credential,CriteriaSet>

Specified by:

resolve in class AbstractCredentialResolver

Throws:

ResolverException

isSatisfyAllPredicates

public boolean isSatisfyAllPredicates()

Get the flag indicating whether resolved credentials must satisfy all predicates (i.e. connected by logical 'AND') or only one or more (connected by logical 'OR').

Returns:

true if must satisfy all, false otherwise

setSatisfyAllPredicates

public void setSatisfyAllPredicates(boolean flag)

Set the flag indicating whether resolved credentials must satisfy all predicates (i.e. connected by logical 'AND') or only one or more (connected by logical 'OR').

Parameters:

flag - true if must satisfy all, false otherwise

resolveFromSource

@Nonnull
protected abstract Iterable<Credential> resolveFromSource(@Nullable
                                                          CriteriaSet criteriaSet)
                                                   throws ResolverException

Subclasses are required to implement this method to resolve credentials from the implementation-specific type of underlying credential source.

Parameters:

criteriaSet - the set of criteria used to resolve credentials from the credential source

Returns:

an Iterable for the resolved set of credentials

Throws:

ResolverException - thrown if there is an error resolving credentials from the credential source

getPredicates

private Set<Predicate<Credential>> getPredicates(@Nullable
                                                 CriteriaSet criteriaSet)
                                          throws ResolverException

Construct a set of credential predicates based on the criteria set.

Parameters:

criteriaSet - the set of credential criteria to process.

Returns:

a set of Credential predicates

Throws:

ResolverException - thrown if there is an error obtaining an instance of EvaluableCredentialCriterion from the EvaluableCredentialCriteriaRegistry
