                    EventManagerIF emanager,

Method Detail

getTransaction

public TopicMapTransactionIF getTransaction()

Description copied from interface: IndexManagerIF

DEPRECATED: Gets the topic map store to which this index manager belongs.

Specified by:

getTransaction in interface IndexManagerIF

Returns:

The topic map store; an object implementing TopicMapStoreIF.

getIndex

public IndexIF getIndex(String name)

Description copied from interface: IndexManagerIF

DEPRECATED: Gets an index by name. An index is usually named by the IndexIF subinterface that it implements.

If no such index is currently active it is created and populated automatically when this method is called. In the case when the index implementation is not dynamic it may take a while for the index to populate itself, depending on the size of the topic map.

Specified by:

getIndex in interface IndexManagerIF

Parameters:

name - A string; the index name, usually the IndexIF subinterface that it implements.

getSupportedIndexes

public Collection<String> getSupportedIndexes()

Description copied from interface: IndexManagerIF

DEPRECATED: Returns the names of the indexes that this index manager supports.

Specified by:

getSupportedIndexes in interface IndexManagerIF

Returns:

A collection of strings which are index names.

getActiveIndexes

public Collection<IndexIF> getActiveIndexes()

Description copied from interface: IndexManagerIF

DEPRECATED: Returns all the active indexes. An active index is an index that has been loaded and populated.

Specified by:

getActiveIndexes in interface IndexManagerIF

Returns:

A collection of IndexIF objects.

isActive

public boolean isActive(String name)

Description copied from interface: IndexManagerIF

DEPRECATED: Returns true if the index is active. An active index is an index that has been loaded and populated. Note that the index need not be up to date.

Specified by:

isActive in interface IndexManagerIF

Parameters:

name - A string which is an index name.

Returns:

Boolean: true if the given index is populated, otherwise false.

registerIndex

public void registerIndex(String name,
                          IndexIF index)

Description copied from class: AbstractIndexManager

INTERNAL: Register the specified index with the index manager.

Specified by:

registerIndex in class AbstractIndexManager

Parameters:

name - The to register the index with name.

index - The index to register.
