Class EventIndexableGraph<T extends IndexableGraph>

java.lang.Object

com.tinkerpop.blueprints.util.wrappers.event.EventGraph<T>

com.tinkerpop.blueprints.util.wrappers.event.EventIndexableGraph<T>

All Implemented Interfaces:

Graph, IndexableGraph, WrapperGraph<T>

Direct Known Subclasses:

EventTransactionalIndexableGraph

public class EventIndexableGraph<T extends IndexableGraph>
extends EventGraph<T>
implements IndexableGraph, WrapperGraph<T>

EventIndexableGraph is merely a proxy to index methods exposing EventGraph methods in the "evented" way. Like the EventGraph it extends from, this graph implementations raise notifications to the listeners for the following events: new vertex/edge, vertex/edge property changed, vertex/edge property removed, vertex/edge removed.

Method Detail

dropIndex

public void dropIndex(String name)

Description copied from interface: IndexableGraph

Remove an index associated with the graph.

Specified by:

dropIndex in interface IndexableGraph

Parameters:

name - the name of the index to drop

createIndex

public <T extends Element> Index<T> createIndex(String indexName,
                                       Class<T> indexClass,
                                       Parameter... indexParameters)

Description copied from interface: IndexableGraph

Generate an index with a particular name for a particular class.

Specified by:

createIndex in interface IndexableGraph

Type Parameters:

T - the element class that this index is indexing (can be base class)

Parameters:

indexName - the name of the manual index

indexClass - the element class that this index is indexing (can be base class)

indexParameters - a collection of parameters for the underlying index implementation

Returns:

the index created

getIndex

public <T extends Element> Index<T> getIndex(String indexName,
                                    Class<T> indexClass)

Description copied from interface: IndexableGraph

Get an index from the graph by its name and index class. An index is unique up to name.

Specified by:

getIndex in interface IndexableGraph

Type Parameters:

T - the class of the elements being indexed (can be base class)

Parameters:

indexName - the name of the index to retrieve

indexClass - the class of the elements being indexed (can be base class)

Returns:

the retrieved index

getIndices

public Iterable<Index<? extends Element>> getIndices()

Description copied from interface: IndexableGraph

Get all the indices maintained by the graph.

Specified by:

getIndices in interface IndexableGraph

Returns:

the indices associated with the graph
