Class RoutineLookupResult

Object

gudusoft.gsqlparser.dlineage.routine.RoutineLookupResult

public final class RoutineLookupResult
extends Object

What a routine lookup found: a status, the branch of the match, and the distinct candidate declarations in declaration order.

RoutineLookupResult.Status.RESOLVED only for exactly one candidate matched on every named level, with no level one side names and the other omits. A match that needs caller context to fill an omitted level (f against s.f, db..p against db.dbo.p) is RoutineLookupResult.Status.REQUIRES_CONTEXT, and more than one candidate is RoutineLookupResult.Status.AMBIGUOUS: an ambiguous callee binds nothing (the RoutineCallBinder contract).
