getBindingNames
Description copied from interface:TupleExprGets the names of the bindings that are, or can be, returned by this tuple expression when it is evaluated.- Specified by:
getBindingNamesin interfaceTupleExpr- Returns:
- A set of binding names.
-
getAssuredBindingNames
Description copied from interface:TupleExprGets the names of the bindings that are guaranteed to be present in the results produced by this tuple expression.- Specified by:
getAssuredBindingNamesin interfaceTupleExpr- Returns:
- A set of binding names.
-
visit
Description copied from interface:QueryModelNodeVisits this node. The node reports itself to the visitor with the proper runtime type.- Specified by:
visitin interfaceQueryModelNode- 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 classAbstractQueryModelNode- Throws:
X extends Exception
-
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 classAbstractQueryModelNode- Parameters:
current- The current child node.replacement- The new child node.
-
getSignature
Description copied from class:AbstractQueryModelNodeDefault implementation ofQueryModelNode.getSignature()that prints the name of the node's class.- Specified by:
getSignaturein interfaceQueryModelNode- Overrides:
getSignaturein classAbstractQueryModelNode- Returns:
- The node's signature, e.g. SLICE (offset=10, limit=10).
-
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 classObject
-
hashCode
public int hashCode() -
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 interfaceTupleExpr- Overrides:
clonein classAbstractQueryModelNode- Returns:
- A deep clone of this query model node.
