List of execConstructTriples() Examples

Examples of execConstructTriples()

com.hp.hpl.jena.query.QueryExecution.execConstructTriples()
Execute a CONSTRUCT query, returning the results as an iterator of {@link Triple}.
Caution: This method may return duplicate Triples. This method may be useful if you only need the results for stream processing, as it can avoid having to place the results in a Model.

Important: The name of this method is somewhat of a misnomer in that depending on the underlying implementation this typically does not execute the CONSTRUCT query but rather answers a wrapper over an internal data structure that can be used to answer the query. In essence calling this method only returns a plan for executing this query which only gets evaluated when you actually start iterating over the results.
@return An iterator of Triple objects (possibly containing duplicates) generatedby applying the CONSTRUCT template of the query to the bindings in the WHERE clause.
