| Modifier and Type | Method and Description |
|---|---|
UnaryTupleOperator |
clone()
Returns a (deep) clone of this query model node.
|
boolean |
equals(Object other)
Returns true if this query model node and its children are recursively equal to o and its
children.
|
TupleExpr |
getArg()
Gets the argument of this unary tuple operator.
|
Set<String> |
getAssuredBindingNames()
Gets the names of the bindings that are guaranteed to be present in the results produced by this tuple
expression.
|
Set<String> |
getBindingNames()
Gets the names of the bindings that are, or can be, returned by this tuple expression when it is evaluated.
|
int |
hashCode() |
void |
replaceChildNode(QueryModelNode current,
QueryModelNode replacement)
Default implementation of
QueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode) that throws an
IllegalArgumentException indicating that current is not a child node of this node. |
void |
setArg(TupleExpr arg)
Sets the argument of this unary tuple operator.
|
<X extends Exception> |
visitChildren(QueryModelVisitor<X> visitor)
Dummy implementation of
QueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>) that does nothing. |
