Var subjVar,
TupleExpr pathExpression,
Var objVar,
Var conVar,
long minLength)

statements from the specified context scope.
|
ArbitraryLengthPath(Var subject,
TupleExpr pathExpression,
Var object,
long minLength)
Creates a arbitrary-length path that matches a subject-, predicate- and object variable against statements from
all contexts.
|
ArbitraryLengthPath(Var subject,
TupleExpr pathExpression,
Var object,
Var context,

| Modifier and Type | Method and Description |
|---|---|
ArbitraryLengthPath |
clone()
Returns a (deep) clone of this query model node.
|
boolean |

Returns true if this query model node and its children are recursively equal to o and its
children.
|
Set<String> |

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.
|
Var |
