 QueryInfo queryInfo)

Method Details

refineFreeVars

protected void refineFreeVars()

getAssuredBindingNames

public Set<String> getAssuredBindingNames()

Description copied from interface: TupleExpr

Gets the names of the bindings that are guaranteed to be present in the results produced by this tuple expression.

Specified by:

getAssuredBindingNames in interface TupleExpr

Overrides:

getAssuredBindingNames in class StatementPattern

Returns:

A set of binding names.

getTripleRef

public TripleRef getTripleRef()

visitChildren

public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor)
