Class InternalDirectoryInstanceLoaderImpl

java.lang.Object

com.atlassian.crowd.directory.loader.AbstractDirectoryInstanceLoader

com.atlassian.crowd.directory.loader.InternalDirectoryInstanceLoaderImpl

All Implemented Interfaces:

DirectoryInstanceLoader, InternalDirectoryInstanceLoader

public class InternalDirectoryInstanceLoaderImpl
extends AbstractDirectoryInstanceLoader
implements InternalDirectoryInstanceLoader

Loads an implementation of a RemoteDirectory for use at runtime by the Crowd security server.

The getDirectory(com.atlassian.crowd.embedded.api.Directory) method caches instances of RemoteDirectory as allowed in the spec of the interface, but getRawDirectory(Long, String, java.util.Map) returns a new instance every time as required. This class listens for update events on EventPublisher to know when to refresh the cache.

This loads both AbstractInternalDirectory and DelegatedAuthenticationDirectory instances.

                                        throws DirectoryInstantiationException

Description copied from interface: DirectoryInstanceLoader

getRawDirectory in interface InternalDirectoryInstanceLoader

Parameters:

id - Directory ID

className - class name of directory.

directoryAttributes - the configuration attributes to pass to the RemoteDirectory

Returns:

instance of InternalRemoteDirectory.

canLoad

public boolean canLoad(String className)

Specified by:

canLoad in interface DirectoryInstanceLoader

Parameters:

className - class name of directory.

Returns:

true iff the directory can load the directory of the specified class.

getDirectory

public InternalRemoteDirectory getDirectory(Directory directory)
                                     throws DirectoryInstantiationException

Description copied from interface: DirectoryInstanceLoader

Loads the RemoteDirectory implementation class for a specific (already saved) Directory configuration.

Implementations of this method may choose to cache the RemoteDirectory, so this must only be called for Directories that have been successfully saved.

Specified by:

getDirectory in interface DirectoryInstanceLoader

Specified by:

getDirectory in interface InternalDirectoryInstanceLoader

Overrides:

getDirectory in class AbstractDirectoryInstanceLoader

Parameters:

directory - The directory to load the RemoteDirectory implementation from.

Returns:

The RemoteDirectory loaded implementation.

Throws:

DirectoryInstantiationException - If the RemoteDirectory implementation could not be loaded.
