optimize

public void optimize(TupleExpr query,
                     Dataset dataset,
                     BindingSet bindings)

Specified by:

optimize in interface QueryOptimizer

meetOther

public void meetOther(QueryModelNode node)
               throws RepositoryException

Specified by:

meetOther in interface QueryModelVisitor<RepositoryException>

Overrides:

meetOther in class AbstractQueryModelVisitor<RepositoryException>

Throws:

RepositoryException

meetNode

protected void meetNode(QueryModelNode node)
                 throws RepositoryException

Description copied from class: AbstractQueryModelVisitor

Method called by all of the other meet methods that are not overridden in subclasses. This method can be overridden in subclasses to define default behaviour when visiting nodes. The default behaviour of this method is to visit the node's children.

Overrides:

meetNode in class AbstractQueryModelVisitor<RepositoryException>

Parameters:

node - The node that is being visited.

Throws:

RepositoryException

meet
