Interface OntologyOptimizableGraph

public interface OntologyOptimizableGraph

An abstraction layer that helps the OntologyOptimizations determine whether it needs to invalidate caches or whether the graph can benefit from caching at all.

Method Summary

Modifier and Type	Method and Description
String	getOntologyGraphKey() Gets a unique identifier for the graph that is used for caching.
boolean	isOntologyGraph() Checks if this graph is an Ontology graph, i.e.
boolean	isUsingOntologyOptimizations() Checks if OntologyOptimizations caches can be used for this graph.

Method Detail

getOntologyGraphKey

String getOntologyGraphKey()

Gets a unique identifier for the graph that is used for caching. In TopBraid EVN this is the graph ID (of the base graph). This is only ever called after isOntologyOptimizable has been true.

Returns:

the unique key

isOntologyGraph

boolean isOntologyGraph()

Checks if this graph is an Ontology graph, i.e. it may define classes, properties and shapes that may invalidate caches.

Returns:

true if this is an Ontology graph

isUsingOntologyOptimizations

boolean isUsingOntologyOptimizations()

Checks if OntologyOptimizations caches can be used for this graph. In TopBraid this is the case for TeamBufferingGraphs that are either master graphs or a working copy that is not an Ontology project.

Returns:

true if caching should be used
