public OwnedTupleExpr(RepositoryConnection owner,
                      TupleExpr arg)

Method Detail

getOwner

public RepositoryConnection getOwner()

prepare

public void prepare(QueryLanguage queryLn,
                    String qry,
                    Map<String,String> bindings)
             throws RepositoryException,
                    MalformedQueryException

Throws:

RepositoryException

MalformedQueryException

hasQuery

public boolean hasQuery()

evaluate

public CloseableIteration<BindingSet,QueryEvaluationException> evaluate(Dataset dataset,
                                                                        BindingSet bindings)

QueryEvaluationException

visit

public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                 throws X extends Exception

Description copied from interface: QueryModelNode

Visits this node. The node reports itself to the visitor with the proper runtime type.

Throws:

X extends Exception

getSignature

public String getSignature()

Description copied from class: AbstractQueryModelNode

Default implementation of QueryModelNode.getSignature() that prints the name of the node's class.

Specified by:

getSignature in interface QueryModelNode

Overrides:

getSignature in class AbstractQueryModelNode

Returns:

The node's signature, e.g. SLICE (offset=10, limit=10).
