Class Method Details
.execute(query, queryable, **options) {|solution| ... } ⇒ RDF::Graph, ...
Parse and execute the given SPARQL query
string against queriable
.
Requires a queryable object (such as an RDF::Repository), into which the dataset will be loaded.
Optionally takes a list of URIs to load as default or named graphs
into queryable
.
Note, if default or named graphs are specified as options (protocol elements),
or the query references specific default or named graphs the graphs are either
presumed to be existant in queryable
or are loaded into queryable
depending
on the presense and value of the :load_datasets option.
Attempting to load into an immutable queryable
will result in a TypeError.
