Method Detail

toString

public static String toString(String prefix,
                              Graph graph)

Returns a human-consumable representation of graph. The string prefix will appear at the beginning of the string. Nodes may be prefix-compressed using graph's prefix-mapping. This default implementation will display all the triples exposed by the graph, including reification triples.

Parameters:

prefix - the prefix of the string returned

graph - the Graph to render into a string

Returns:

String a human-consumable representation of the argument Graph

getName

public String getName()

getCapabilities

public Capabilities getCapabilities()

Specified by:

getCapabilities in interface Graph

Overrides:

getCapabilities in class GraphBase

getPrefixMapping

public PrefixMapping getPrefixMapping()

Specified by:

getPrefixMapping in interface Graph

Overrides:

getPrefixMapping in class GraphBase

getTransactionHandler

public TransactionHandler getTransactionHandler()

Specified by:

getTransactionHandler in interface Graph

Overrides:

getTransactionHandler in class GraphBase

toString

public String toString()

Overrides:

toString in class GraphBase

performAdd

public void performAdd(Triple t)

Specified by:

performAdd in interface GraphWithPerform

Overrides:

performAdd in class GraphBase

performDelete

public void performDelete(Triple t)

Specified by:

performDelete in interface GraphWithPerform

Overrides:

performDelete in class 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 GraphBase

clear

public void clear()

Specified by:

clear in interface Graph

Overrides:

clear in class GraphBase

remove

public void remove(Node s,
                   Node p,
                   Node o)

Specified by:

remove in interface Graph

Overrides:

remove in class GraphBase
