Class ScopedNameKey

Object

gudusoft.gsqlparser.dlineage.util.ScopedNameKey

public final class ScopedNameKey
extends Object

The lineage model's key for a name that is only meaningful inside a scope: a table alias inside one statement, a variable or cursor inside one routine. The scope and the name are kept apart as structure, never joined into one string, so no spelling of a name can collide with the text of a scope, and the name keeps the identity key the name service minted for it.

In-process only, like the keys it holds.
