All Implemented Interfaces:

CredentialResolver, Resolver<Credential,CriteriaSet>

Direct Known Subclasses:

BasicProviderKeyInfoCredentialResolver, CollectionCredentialResolver, FilesystemCredentialResolver, KeyStoreCredentialResolver

public abstract class AbstractCriteriaFilteringCredentialResolver
extends AbstractCredentialResolver

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

Methods

Modifier and Type	Method and Description
boolean	isMeetAllCriteria() Get whether all EvaluableCredentialCriteria must be met to return a credential, or only one or more evaluable criteria.
boolean	isUnevaluableSatisfies() Get the flag which determines the processing behavior when an EvaluableCredentialCriteria is unable to evaluate a Credential.
Iterable<Credential>	resolve(CriteriaSet criteriaSet) Process the specified criteria and return the resulting instances the the product type which satisfy the criteria.
protected abstract Iterable<Credential>	resolveFromSource(CriteriaSet criteriaSet) Subclasses are required to implement this method to resolve credentials from the implementation-specific type of underlying credential source.
void	setMeetAllCriteria(boolean flag) Set whether all EvaluableCredentialCriteria must be met to return a credential, or only one or more evaluable criteria.
void	setUnevaluableSatisfies(boolean flag) Set the flag which determines the processing behavior when an EvaluableCredentialCriteria is unable to evaluate a Credential.

Method Detail

resolve

public Iterable<Credential> resolve(CriteriaSet criteriaSet)
                             throws SecurityException

Process the specified criteria and return the resulting instances the the product type which satisfy the criteria.

Specified by:

resolve in interface Resolver<Credential,CriteriaSet>

Specified by:

resolve in class AbstractCredentialResolver

Parameters:

criteriaSet - the criteria to evaluate or process

Returns:

instances which satisfy the criteria

Throws:

SecurityException - thrown if there is an error processing the specified criteria

isMeetAllCriteria

public boolean isMeetAllCriteria()

Get whether all EvaluableCredentialCriteria must be met to return a credential, or only one or more evaluable criteria. See also CriteriaFilteringIterator.

Returns:

Returns the meetAllCriteria flag.

setMeetAllCriteria

public void setMeetAllCriteria(boolean flag)

Set whether all EvaluableCredentialCriteria must be met to return a credential, or only one or more evaluable criteria. See also CriteriaFilteringIterator.

Parameters:

flag - the new meetAllCriteria flag value.

isUnevaluableSatisfies

public boolean isUnevaluableSatisfies()

Get the flag which determines the processing behavior when an EvaluableCredentialCriteria is unable to evaluate a Credential. See also CriteriaFilteringIterator.

Returns:

Returns the unevaluableSatisfies flag.

setUnevaluableSatisfies

public void setUnevaluableSatisfies(boolean flag)

Set the flag which determines the processing behavior when an EvaluableCredentialCriteria is unable to evaluate a Credential. See also CriteriaFilteringIterator.

Parameters:

flag - the new unevaluableSatisfies flag value.

resolveFromSource

protected abstract Iterable<Credential> resolveFromSource(CriteriaSet criteriaSet)
                                                   throws SecurityException

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:

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