isSameNodeKind
Description copied from class:ValueNode
Some node classes represent several logical node types (to reduce footprint), which we call kinds. This means that implementations ofValueNode.isEquivalent(org.apache.derby.impl.sql.compile.ValueNode)
cannot always just useinstanceof
to check if the other node represents the same kind. Hence this method needs to be overridden by all node classes that represent several kinds. This default implementation does not look at kinds. It is only called from implementations ofisEquivalent
.- Overrides:
isSameNodeKind
in classBinaryOperatorNode
- Parameters:
o
- The other value node whose kind we want to compare with.- Returns:
true
ifthis
ando
represent the same logical node type, i.e. kind.
