Class InternalDirectoryInstanceLoaderImpl

java.lang.Object
  com.atlassian.crowd.directory.loader.CachingDirectoryInstanceLoader
      com.atlassian.crowd.directory.loader.InternalDirectoryInstanceLoaderImpl

All Implemented Interfaces:

DirectoryInstanceLoader, InternalDirectoryInstanceLoader

public class InternalDirectoryInstanceLoaderImpl
extends CachingDirectoryInstanceLoader
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.

InternalDirectoryInstanceLoaderImpl(InstanceFactory instanceFactory, com.atlassian.event.api.EventPublisher eventPublisher)

Method Summary

boolean	canLoad(String className)
InternalRemoteDirectory	getDirectory(Directory directory) Loads the RemoteDirectory implementation class for a specific (already saved) Directory configuration.
protected RemoteDirectory	getNewDirectory(Directory directory) Always returns a new instance of a RemoteDirectory.
InternalRemoteDirectory	getRawDirectory(Long id, String className, Map<String,String> directoryAttributes) Loads a guaranteed un-cached directory implementation for a specific configuration.

Method Detail

getRawDirectory

public InternalRemoteDirectory getRawDirectory(Long id,
                                               String className,
                                               Map<String,String> directoryAttributes)
                                        throws DirectoryInstantiationException

Description copied from interface: DirectoryInstanceLoader

Loads a guaranteed un-cached directory implementation for a specific configuration.

Specified by:

getRawDirectory in interface DirectoryInstanceLoader

Specified by:

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.

Throws:

DirectoryInstantiationException - if a RemoteDirectory implementation can not be loaded.

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 CachingDirectoryInstanceLoader

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.

getNewDirectory

protected RemoteDirectory getNewDirectory(Directory directory)
                                   throws DirectoryInstantiationException

Description copied from class: CachingDirectoryInstanceLoader

Always returns a new instance of a RemoteDirectory.

Specified by:

getNewDirectory in class CachingDirectoryInstanceLoader

Parameters:

directory - directory configuration

Returns:

new instance of a RemoteDirectory

Throws:

DirectoryInstantiationException - if the directory could not be instantiated.
