Method Detail

getParsedQuery

public ParsedQuery getParsedQuery()

getConnection

protected SailRepositoryConnection getConnection()

enforceMaxQueryTime

protected CloseableIteration<? extends BindingSet,QueryEvaluationException> enforceMaxQueryTime(CloseableIteration<? extends BindingSet,QueryEvaluationException> bindingsIter)

getActiveDataset

public Dataset getActiveDataset()

Gets the "active" dataset for this query. The active dataset is either the dataset that has been specified using AbstractOperation.setDataset(Dataset) or the dataset that has been specified in the query, where the former takes precedence over the latter.

Returns:

The active dataset, or null if there is no dataset.
