Constructor Detail

FilterServerMechanismFactory

public FilterServerMechanismFactory(HttpServerAuthenticationMechanismFactory delegate,
                                    Predicate<String> predicate)

Constructs a new instance.

Parameters:

delegate - the HttpServerAuthenticationMechanismFactory to delegate to.

predicate - mechanism name based predicate to filter available mechanisms.

FilterServerMechanismFactory

public FilterServerMechanismFactory(HttpServerAuthenticationMechanismFactory delegate,
                                    boolean include,
                                    String... mechanismNames)

Construct a new instance that filters from a provided set of mechanism names.

Parameters:

delegate - the HttpServerAuthenticationMechanismFactory to delegate to.

include - when true mechanisms will be advertised as available if included in the provided mechanismNames.

mechanismNames - the mechanism names to use as a filter.

FilterServerMechanismFactory

public FilterServerMechanismFactory(HttpServerAuthenticationMechanismFactory delegate,
                                    boolean include,
                                    Collection<String> mechanismNames)

Construct a new instance that filters from a provided set of mechanism names.

Parameters:

delegate - the HttpServerAuthenticationMechanismFactory to delegate to.

include - when true mechanisms will be advertised as available if included in the provided mechanismNames.

mechanismNames - the mechanism names to use as a filter.

Method Detail

getMechanismNames

public String[] getMechanismNames(Map<String,?> properties)

Get the available mechanism names after filtering has been performed by the previously provided Predicate

Specified by:

getMechanismNames in interface HttpServerAuthenticationMechanismFactory

Parameters:

properties - the Map of properties to pass into the HttpServerAuthenticationMechanismFactory.getMechanismNames(Map) call on the delegate.

Returns:

The array of filtered mechanism names.

createAuthenticationMechanism

public HttpServerAuthenticationMechanism createAuthenticationMechanism(String mechanismName,
                                                                       Map<String,?> properties,
                                                                       CallbackHandler callbackHandler)
                                                                throws HttpAuthenticationException

Create the requested HttpServerAuthenticationMechanism provided it is available and allowed by the current filter.

Specified by:

createAuthenticationMechanism in interface HttpServerAuthenticationMechanismFactory

Parameters:

mechanismName - the name of the required mechanism.

properties - the configuration properties to pass in for mechanism creation.

callbackHandler - the CallbackHandler the mechanism should use for verification.

Returns:

The HttpServerAuthenticationMechanism or null if not available.

Throws:

HttpAuthenticationException
