BusinessServiceGraphProvider

public BusinessServiceGraphProvider(GraphContainerCache graphContainerCache,
                                    BusinessServiceManager businessServiceManager,

Method Detail

loadGraph

public ImmutableGraph<?,?> loadGraph()

Description copied from interface: GraphProvider

Loads the graph, this GraphProvider handles. Loading may be performed very quickly, but also may take some time.

Specified by:

loadGraph in interface GraphProvider

Returns:

The populated graph.

getGraphInfo

public GraphInfo getGraphInfo()

Description copied from interface: GraphProvider

The GraphInfo should be used to provide details of the graph's nature, e.g. the namespace, label or description A ImmutableGraph should also embed this information. The difference is, that the info should always be available, even if the graph is not yet loaded, and should also never change during the provider's live time, whereas the graph itself may change (e.g. different vertices/edges and properties (besides the ones defining the info)).

Specified by:

getGraphInfo in interface GraphProvider

Returns:

the meta information of the graph

getName

public java.lang.String getName()

Description copied from interface: EventListener

Return the id of the listener

Specified by:

getName in interface EventListener

Returns:

a String object.
