visit
public <X extends Exception> void visit(QueryModelVisitor<X> visitor) throws X extends Exception
Description copied from interface:QueryModelNodeVisits 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: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:
equalsin interfaceQueryModelNode- Overrides:
equalsin classAbstractAggregateOperator
-
hashCode
public int hashCode()
- Overrides:
hashCodein classAbstractAggregateOperator
-
clone
public AggregateFunctionCall 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 interfaceAggregateOperator- Specified by:
clonein interfaceQueryModelNode- Specified by:
clonein interfaceValueExpr- Overrides:
clonein classAbstractAggregateOperator- Returns:
- A deep clone of this query model node.
