visit
Description copied from interface:QueryModelNode
Visits this node. The node reports itself to the visitor with the proper runtime type.- Specified by:
visit
in interfaceQueryModelNode
- Throws:
X
-
visitChildren
Description copied from class:AbstractQueryModelNode
Dummy implementation ofQueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>)
that does nothing. Subclasses should override this method when they have child nodes.- Specified by:
visitChildren
in interfaceQueryModelNode
- Overrides:
visitChildren
in classAbstractQueryModelNode
- Throws:
X

clone
Description copied from interface:QueryModelNode
Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.- Specified by:
clone
in interfaceQueryModelNode
- Specified by:
clone
in interfaceValueExpr
- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
