Description copied from interface:QueryModelNodeSets the node's parent.- Specified by:
setParentNodein interfaceQueryModelNode- Overrides:
setParentNodein classAbstractQueryModelNode- Parameters:
parent- The parent node for this node.

replacement- The new node.
-
getSignature
public String getSignature()
Description copied from class:AbstractQueryModelNodeDefault implementation ofQueryModelNode.getSignature()that prints the name of the node's class.- Specified by:
getSignaturein interfaceQueryModelNode- Overrides:
getSignaturein classAbstractQueryModelNode- Returns:
- The node's signature, e.g. SLICE (offset=10, limit=10).
-
equals
public boolean equals(Object o)
Description copied from interface:QueryModelNodeReturns true if this query model node and its children are recursively equal to o and its children.- Specified by:
