 Var reifVar)

Method Details

getReifVar

public Var getReifVar()

setReifVar

public void setReifVar(Var reifVar)

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 interface TupleExpr

Overrides:

getAssuredBindingNames in class TripleRef

Returns:

A set of binding names.

getVars

public <L extends Collection<Var>> L getVars(L varCollection)

Description copied from class: TripleRef

Adds the variables of this statement pattern to the supplied collection.

Overrides:

getVars in class TripleRef

visit

public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                 throws X

Description copied from interface: QueryModelNode

Visits this node. The node reports itself to the visitor with the proper runtime type.

Specified by:

visit in interface QueryModelNode

Overrides:

visit in class TripleRef

Throws:

X

visitChildren

public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor)
                                         throws X

Description copied from interface: QueryModelNode

Visits the children of this node. The node calls QueryModelNode.visit(QueryModelVisitor) on all of its child nodes.

Specified by:

visitChildren in interface QueryModelNode

Overrides:

visitChildren in class TripleRef

Throws:

X

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 interface QueryModelNode

Overrides:

replaceChildNode in class TripleRef

Parameters:

current - The current child node.

replacement - The new child node.

getSignature

public String getSignature()

Description copied from class: AbstractQueryModelNode

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

Specified by:

getSignature in interface QueryModelNode

Overrides:

getSignature in class TripleRef

Returns:

The node's signature, e.g. SLICE (offset=10, limit=10).

equals

public boolean equals(Object other)

Description copied from interface: QueryModelNode

Returns true if this query model node and its children are recursively equal to o and its children.

Specified by:

equals in interface QueryModelNode

Overrides:

equals in class TripleRef

hashCode

public int hashCode()

Overrides:

hashCode in class TripleRef

clone

public TripleRef 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 interface QueryModelNode

Specified by:

clone in interface TupleExpr

Overrides:

clone in class TripleRef

Returns:

A deep clone of this query model node.
