visit
Description copied from interface:QueryModelNode
Visits this node. The node reports itself to the visitor with the proper runtime type.- Throws:
X
-
visitChildren
Description copied from interface:QueryModelNode
Visits the children of this node. The node callsQueryModelNode.visit(QueryModelVisitor)
on all of its child nodes.- Throws:
X
-
replaceChildNode
Description copied from interface:QueryModelNode
Replaces one of the child nodes with a new node.- Parameters:
current
- The current child node.replacement
- The new child node.
-
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).
-
equals
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
-
hashCode
-
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
- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
