clone()
Returns a (deep) clone of this query model node.
|

equals(Object other)
Returns true if this query model node and its children are recursively equal to o and its
children.

getAggregateBindingNames() |
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.

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

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. |

visitChildren(QueryModelVisitor<X> visitor)
Dummy implementation of
QueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>) that does nothing. |
