Package com.atlassian.confluence.impl.crowd.directory

Class CacheableDirectoryInstanceLoader

java.lang.Object

com.atlassian.confluence.impl.crowd.directory.CacheableDirectoryInstanceLoader

All Implemented Interfaces:

com.atlassian.crowd.directory.loader.DirectoryInstanceLoader

public class CacheableDirectoryInstanceLoader
extends Object
implements com.atlassian.crowd.directory.loader.DirectoryInstanceLoader

Caches the underlying remote directory base by id.

Note, this caching refers to holding the RemoteDirectory instances in memory, not the db caching which may occur in underlying implementations.

The problem with this approach is that every DC node is going to have it's own directory instance.

Since:

5.10

getDirectory

public com.atlassian.crowd.directory.RemoteDirectory getDirectory(com.atlassian.crowd.embedded.api.Directory directory)
                                                           throws com.atlassian.crowd.exception.DirectoryInstantiationException

Create a directory instance from configuration

We MUST only serve a single instance of DbCachingRemoteDirectory per directory ID because of concurrency controls on the DbCachingRemoteDirectory sync refresh. This is achieved by atomically creating RemoteDirectory only if it hasn't exist yet

Specified by:

getDirectory in interface com.atlassian.crowd.directory.loader.DirectoryInstanceLoader

Parameters:

directory - directory configuration

Returns:

new of already computed instance of RemoteDirectory

Throws:

com.atlassian.crowd.exception.DirectoryInstantiationException - if directory creation failed for whatever reason

getRawDirectory

public com.atlassian.crowd.directory.RemoteDirectory getRawDirectory(Long id,
 String className,
 Map<String,String> attributes)
                                                              throws com.atlassian.crowd.exception.DirectoryInstantiationException

Specified by:

getRawDirectory in interface com.atlassian.crowd.directory.loader.DirectoryInstanceLoader

Throws:

com.atlassian.crowd.exception.DirectoryInstantiationException
