Method Detail

addDefaultGraph

void addDefaultGraph(java.net.URI name)

Adds (by RDF merge) the graph represented by name to the default graph for this dataset

Parameters:

name - Identifier of the graph being added

addNamedGraph

void addNamedGraph(java.net.URI name)

Parameters:

name - Identifier of the graph being added

setDefaultGraphs

void setDefaultGraphs(java.util.Set<java.net.URI> graphs)

Sets the full set of graphs that are merged to form the default graph for this dataset.

Parameters:

graphs - The new graphs that form the default graph

setNamedGraphs

void setNamedGraphs(java.util.Set<java.net.URI> graphs)

Sets the full set of graphs that comprise the named graph portion of this dataset

Parameters:

graphs - The new named graphs

getDefaultGraph
