Class LibRDF_GraphQueryResults

Description
Description | Vars | Methods (details)

A specialized librdf_query_results wrapper for graph results.

Graph results are returned by queries that construct a graph based on triples that meet certain conditions such as those using the "CONSTRUCT" or "DESCRIBE" SPARQL keywords.

Iterating over this class will result in a stream of LibRDF_Statement objects, similar to the result of iterating over a LibRDF_Model.
