| Modifier and Type | Method and Description |
|---|---|
TripleRef |
clone()
Returns a (deep) clone of this query model node.
|
boolean |
equals(Object other)
Returns true if this query model node and its children are recursively equal to o and its
children.
|
Set<String> |
getAssuredBindingNames()
Gets the names of the bindings that are guaranteed to be present in the results produced by this tuple
expression.
|
Set<String> |
getBindingNames()
Gets the names of the bindings that are, or can be, returned by this tuple expression when it is evaluated.
|

getExprVar()
Returns the context variable, if available.
|
Var |

getSignature()
Default implementation of
QueryModelNode.getSignature() that prints the name of the node's class. |

List<Var> |
getVarList() |
<L extends Collection<Var>> |
getVars(L varCollection)
Adds the variables of this statement pattern to the supplied collection.

void |
replaceChildNode(QueryModelNode current,
QueryModelNode replacement)
Default implementation of
QueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode) that throws an
IllegalArgumentException indicating that current is not a child node of this node. |
