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.
-
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.
-
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.
-
equals
public boolean equals(Object obj)
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 interfaceQueryModelNode
- Overrides:
equals
in classObject
-
clone
public BindingSetAssignment 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.
-
getSupportedOrders
public Set<Var> getSupportedOrders(AvailableStatementOrder tripleSource)
- Specified by:
getSupportedOrders
in interfaceTupleExpr
-
setBindingNames
public void setBindingNames(Set<String> bindingNames)
- Parameters:
bindingNames
- The bindingNames to set if known.
-
setBindingSets
public void setBindingSets(Iterable<BindingSet> bindingSets)
- Parameters:
bindingSets
- The bindingSets to set.
-
getBindingSets
public Iterable<BindingSet> getBindingSets()
- Returns:
- Returns the bindingSets.
-
getSignature
public String getSignature()
Description copied from class:AbstractQueryModelNode
Default implementation ofQueryModelNode.getSignature()
that prints the name of the node's class.- Specified by:
getSignature
in interfaceQueryModelNode
- Overrides:
getSignature
in classAbstractQueryModelNode
- Returns:
- The node's signature, e.g. SLICE (offset=10, limit=10).
-
shouldCacheCardinality
protected boolean shouldCacheCardinality()
- Overrides:
shouldCacheCardinality
in classAbstractQueryModelNode
