Method Detail

getNamespaces

public Map<String,String> getNamespaces()

Description copied from interface: GraphQueryResult

Retrieves relevant namespaces from the query result.
The contents of the Map may be modified after it is returned, as the initial return may be performed when the first RDF Statement is encountered.

Specified by:

getNamespaces in interface GraphQueryResult

Returns:

a Map<String, String> object containing (prefix, namespace) pairs.
