visit
Description copied from interface:QueryModelNodeVisits this node. The node reports itself to the visitor with the proper runtime type.- Throws:
X extends Exception
-
visitChildren
Description copied from class:AbstractQueryModelNodeDummy 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:
visitChildrenin interfaceQueryModelNode- Overrides:
visitChildrenin classBinaryValueOperator- Throws:
X extends Exception
-
equals
Description copied from interface:QueryModelNodeReturns true if this query model node and its children are recursively equal to o and its children.- Specified by:
equalsin interfaceQueryModelNode- Overrides:
equalsin classBinaryValueOperator
-
replaceChildNode
Description copied from class:AbstractQueryModelNodeDefault implementation ofQueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode)that throws anIllegalArgumentExceptionindicating that current is not a child node of this node.- Specified by:
replaceChildNodein interfaceQueryModelNode- Overrides:
replaceChildNodein classBinaryValueOperator- Parameters:
current- The current child node.replacement- The new child node.
-
hashCode
public int hashCode()- Overrides:
hashCodein classBinaryValueOperator
-
clone
Description copied from interface:QueryModelNodeReturns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.- Specified by:
clonein interfaceQueryModelNode- Specified by:
clonein interfaceValueExpr- Overrides:
clonein classBinaryValueOperator- Returns:
- A deep clone of this query model node.
