Method Detail

getName

public String getName()

getBulkUpdateHandler

public BulkUpdateHandler getBulkUpdateHandler()

Specified by:

getBulkUpdateHandler in interface Graph

Overrides:

getBulkUpdateHandler in class com.hp.hpl.jena.graph.impl.GraphBase

getCapabilities

public Capabilities getCapabilities()

Specified by:

getCapabilities in interface Graph

Overrides:

getCapabilities in class com.hp.hpl.jena.graph.impl.GraphBase

getPrefixMapping

public PrefixMapping getPrefixMapping()

Specified by:

getPrefixMapping in interface Graph

Overrides:

getPrefixMapping in class com.hp.hpl.jena.graph.impl.GraphBase

getTransactionHandler

public TransactionHandler getTransactionHandler()

Specified by:

getTransactionHandler in interface Graph

Overrides:

getTransactionHandler in class com.hp.hpl.jena.graph.impl.GraphBase

toString

public String toString()

Overrides:

toString in class com.hp.hpl.jena.graph.impl.GraphBase

toString

public static String toString(String prefix,
                              Graph that)

Answer a human-consumable representation of that. The string prefix will appear near the beginning of the string. Nodes may be prefix-compressed using that's prefix-mapping. This default implementation will display all the triples exposed by the graph (ie including reification triples if it is Standard).

performAdd

public void performAdd(Triple t)

Specified by:

performAdd in interface com.hp.hpl.jena.graph.impl.GraphWithPerform

Overrides:

performAdd in class com.hp.hpl.jena.graph.impl.GraphBase

performDelete

public void performDelete(Triple t)

Specified by:

performDelete in interface com.hp.hpl.jena.graph.impl.GraphWithPerform

Overrides:

performDelete in class com.hp.hpl.jena.graph.impl.GraphBase

isEmpty

public boolean isEmpty()

Answer true iff this graph contains no triples. Implemented using a SPARQL ASK for any triple in the graph's dataset; on large databases this is faster than determining whether the graph's size is zero.

Specified by:

isEmpty in interface Graph

Overrides:

isEmpty in class com.hp.hpl.jena.graph.impl.GraphBase
