visit
Description copied from interface:QueryModelNodeVisits this node. The node reports itself to the visitor with the proper runtime type.- Specified by:
visitin interfaceQueryModelNode- Throws:
X extends Exception
-
visitChildren
Description copied from interface:QueryModelNodeVisits the children of this node. The node callsQueryModelNode.visit(QueryModelVisitor)on all of its child nodes.- Specified by:
visitChildrenin interfaceQueryModelNode- Throws:
X extends Exception
-
replaceChildNode
Description copied from interface:QueryModelNodeReplaces one of the child nodes with a new node.- Specified by:
replaceChildNodein interfaceQueryModelNode- Parameters:
current- The current child node.replacement- The new child node.

clone
Description copied from interface:QueryModelNodeReturns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.- Specified by:
clonein interfaceQueryModelNode- Specified by:
clonein interfaceValueExpr- Overrides:
clonein classAbstractQueryModelNode- Returns:
- A deep clone of this query model node.
