Constructor	Description
ServiceLoaderServerMechanismFactory(ClassLoader classLoader)	Constructs a new instance, a ServiceLoader will be created from the supplied ClassLoader
ServiceLoaderServerMechanismFactory(ServiceLoader<HttpServerAuthenticationMechanismFactory> serviceLoader)	Constructs a new instance with a previously created ServiceLoader This class synchronizes on the supplied service loader, if the same is synchronized against outside then ServiceLoader.reload() can safely be called.

Constructor Detail

ServiceLoaderServerMechanismFactory

public ServiceLoaderServerMechanismFactory(ServiceLoader<HttpServerAuthenticationMechanismFactory> serviceLoader)

Constructs a new instance with a previously created ServiceLoader This class synchronizes on the supplied service loader, if the same is synchronized against outside then ServiceLoader.reload() can safely be called.

Parameters:

serviceLoader - the ServiceLoader to use to locate HttpServerAuthenticationMechanismFactory instances.

ServiceLoaderServerMechanismFactory

public ServiceLoaderServerMechanismFactory(ClassLoader classLoader)

Constructs a new instance, a ServiceLoader will be created from the supplied ClassLoader

Parameters:

classLoader - the ClassLoader to use to construct a ServiceLoader.

Method Detail

getMechanismNames

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

Description copied from interface: HttpServerAuthenticationMechanismFactory

Get the names of the HTTP authentication mechanisms that can be supplied by this factory filtered by the supplied properties.

Specified by:

getMechanismNames in interface HttpServerAuthenticationMechanismFactory

Parameters:

properties - the non-null set of properties to pass configuration to the mechanisms that may be evaluated for mechanism availability.

Returns:

A non-null array of the names of the supported HTTP authentication mechanisms.

Description copied from interface: HttpServerAuthenticationMechanismFactory

Obtain an instance of the authentication mechanism requested provided this is allowed by any policy specified within the supplied properties.

Specified by:

createAuthenticationMechanism in interface HttpServerAuthenticationMechanismFactory

Parameters:

mechanismName - The non-null name of the mechanism to create.

properties - The non-null set of properties to select and configure the mechanism that may be evaluated for mechanism availability.

callbackHandler - The non-null CallbackHandler for use by the mechanism during authentication.

Returns:

the configured HttpServerAuthenticationMechanism or null if no mechanism could be resolved for the given mechanism name.

Throws:

HttpAuthenticationException - if there is an error creating the mechanism.
