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.- Throws:
X extends Exception

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).
-
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 ProjectionElem clone()
Description copied from interface:QueryModelNode

in interfaceQueryModelNode
- Overrides:
clone
in classAbstractQueryModelNode
- Returns:
- A deep clone of this query model node.
-
hasAggregateOperatorInExpression
