Doc from org.apache.derby.impl.sql.compile.ValueNode.isSameNodeKind.

Some node classes represent several logical node types (to reduce footprint), which we call kinds. This means that implementations of isEquivalent cannot always just use instanceof 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 of isEquivalent.

Parameters
o:ValueNode

The other value node whose kind we want to compare with.

Returns:boolean

true if this and o represent the same logical node type, i.e. kind.
