Class TopicMapSourceManager

java.lang.Object

net.ontopia.topicmaps.entry.TopicMapSourceManager

All Implemented Interfaces:

TopicMapRepositoryIF

public class TopicMapSourceManager
extends Object
implements TopicMapRepositoryIF

INTERNAL: This is the primary implementation of the TopicMapRepositoryIF interface. This class also implements the TopicMapSourceIF interface making it a topic map source that behaves as a facade for the results of multiple topic map sources.

The reference keys used are the reference ids retrieved from reference.getId(). An exception will be thrown if there are duplicate reference keys.

The sources that are added to the repository must have unique ids. If the source id is not specified, the source cannot be looked up by id.

Method Detail

getReferences

public Collection<TopicMapReferenceIF> getReferences()

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Returns a collection containing all references.

Specified by:

getReferences in interface TopicMapRepositoryIF

getReferenceKeys

public Collection<String> getReferenceKeys()

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Returns a collection containing the keys of all references.

Specified by:

getReferenceKeys in interface TopicMapRepositoryIF

getReferenceByKey

public TopicMapReferenceIF getReferenceByKey(String key)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Gets a topic map reference by its reference key. Returns null if not found.

Specified by:

getReferenceByKey in interface TopicMapRepositoryIF

getReferenceKey

public String getReferenceKey(TopicMapReferenceIF ref)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Gets the key used to identify the reference in the repository.

Specified by:

getReferenceKey in interface TopicMapRepositoryIF

createStore

public TopicMapStoreIF createStore(String refkey,
                                   boolean readonly)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Creates a new topic map store for the given topic map id. This method effectively delegates the call to the underlying topic map reference. An exception is thrown if the topic map reference cannot be found or any errors occurs while loading it.

Specified by:

createStore in interface TopicMapRepositoryIF

getSourceById

public TopicMapSourceIF getSourceById(String source_id)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Returns the topic map source that has the given source id.

Specified by:

getSourceById in interface TopicMapRepositoryIF

getSources

public Collection<TopicMapSourceIF> getSources()

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Returns an immutable collection containing the TopicMapSourceIFs registered with the topic map repository.

Specified by:

getSources in interface TopicMapRepositoryIF

addSource

public void addSource(TopicMapSourceIF source)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Adds the source to the repository.

Specified by:

addSource in interface TopicMapRepositoryIF

removeSource

public void removeSource(TopicMapSourceIF source)

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Removes the source from the repository.

Specified by:

removeSource in interface TopicMapRepositoryIF

refresh

public void refresh()

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Refreshes all sources and recreates the reference map.

Specified by:

refresh in interface TopicMapRepositoryIF

createReferenceKey

protected String createReferenceKey(TopicMapReferenceIF ref)

INTERNAL: Creates a unique id. This method is used by the refresh method to generate unique ids for topic map references.

close

public void close()

Description copied from interface: TopicMapRepositoryIF

PUBLIC: Closes the repository and releases all resources bound by the repository. Closing the repository will also close any open topic map references held by the topic map repository as well as the topic map sources added to it.

Specified by:

close in interface TopicMapRepositoryIF
