visitChildren
public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor) throws X extends Exception
Description copied from class:AbstractQueryModelNode
Dummy implementation ofQueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>)
that does nothing. Subclasses should override this method when they have child nodes.- Specified by:
visitChildren
in interfaceQueryModelNode
- Overrides:
visitChildren
in classAbstractQueryModelNode
- Throws:
X extends Exception
-
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 interfaceQueryModelNode
- Overrides:
equals
in classObject
-
clone
public ValueExprTripleRef 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 interfaceValueExpr
- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
-
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
-
replaceChildNode
public void replaceChildNode(QueryModelNode current, QueryModelNode replacement)
Description copied from class:AbstractQueryModelNode
Default implementation ofQueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode)
that throws anIllegalArgumentException
indicating that current is not a child node of this node.- Specified by:
replaceChildNode
in interfaceQueryModelNode
- Overrides:
replaceChildNode
in classAbstractQueryModelNode
- Parameters:
current
- The current child node.replacement
- The new child node.
