##
# The SPARQL GraphPattern `graph` operator.
#
# This is a wrapper to add a `context` to the query.
#
# @example
# (prefix ((: <http://example/>))
# (graph ?g
# (bgp (triple ?s ?p ?o))))
#
# @see http://www.w3.org/TR/rdf-sparql-query/#sparqlAlgebra

# A `graph` is an RDF::Query with a context.

# @param [RDF::Query] bgp
# @return [RDF::Query]
