visit
public <X extends Exception> void visit(QueryModelVisitor<X> visitor) throws X extends Exception
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 extends Exception
-
visitChildren
public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor) throws X extends Exception
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 extends Exception
-
replaceChildNode
public void replaceChildNode(QueryModelNode current, QueryModelNode replacement)
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
public FedXService 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

- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
-
getAssuredBindingNames
public Set<String> 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
public Set<String> 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:
getBindingNames
in interfaceTupleExpr
- Returns:
- A set of binding names.
-
