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 interface:QueryModelNode
Visits the children of this node. The node callsQueryModelNode.visit(QueryModelVisitor)
on all of its child nodes.- Specified by:
visitChildren
in interfaceQueryModelNode
- Throws:
X
-
replaceChildNode
Description copied from interface:QueryModelNode
Replaces one of the child nodes with a new node.- Specified by:
replaceChildNode
in interfaceQueryModelNode
- Parameters:
current
- The current child node.replacement
- The new child node.
-
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 interfaceTupleExpr
- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
-
getAssuredBindingNames
Description copied from interface:TupleExpr
Gets the names of the bindings that are guaranteed to be present in the results produced by this tuple expression.- Specified by:
getAssuredBindingNames
in interfaceTupleExpr
- Returns:
- A set of binding names.
-
getBindingNames
Description copied from interface:TupleExpr
Gets the names of the bindings that are, or can be, returned by this tuple expression when it is evaluated.- Specified by:
