Class RoutineRegistry

Object

gudusoft.gsqlparser.dlineage.routine.RoutineRegistry

public final class RoutineRegistry
extends Object

The routines declared in one analysis, by identity, with ordered alias indexes for lookups.

A declaration with the identity of an earlier one replaces it in place (CREATE OR REPLACE, a package body after its specification). Lookups compare written names level by level (RoutineName): the terminal through a per-kind index, the containers by their keys and states, then the argument alias: a name-only lookup matches declarations keyed by name only, a lookup with n arguments matches a declaration's total or input count. The result says how it matched and whether it is unique (RoutineLookupResult); it never picks the first of several.

Method Summary

Modifier and Type	Method and Description
RoutineDeclaration	declare(RoutineDeclaration declaration) Adds a declaration, or replaces the current occurrence of its identity; returns the declaration it replaced, or null.
RoutineDeclaration	find(RoutineDeclaration.Identity identity) The current occurrence of an identity, or null.
List<RoutineDeclaration>	getDeclarations()
RoutineLookupResult	lookup(List<RoutineName> interpretations, Integer argumentCount) Looks a routine up by the interpretations of its written name and, when the call site keys it with one, the argument count (null for a name-only lookup).
RoutineLookupResult	lookup(List<RoutineName> interpretations, Integer argumentCount, CatalogObjectKind wanted, Collection<Object> visibleScopes) A lookup for a routine of wanted kind (ROUTINE when the call site does not say), seeing the local routines declared in visibleScopes (the routines enclosing the call); triggers are not callable.

Method Detail

declare

public RoutineDeclaration declare(RoutineDeclaration declaration)

Adds a declaration, or replaces the current occurrence of its identity; returns the declaration it replaced, or null.

find

public RoutineDeclaration find(RoutineDeclaration.Identity identity)

The current occurrence of an identity, or null.

getDeclarations

public List<RoutineDeclaration> getDeclarations()

lookup

public RoutineLookupResult lookup(List<RoutineName> interpretations,
                                  Integer argumentCount)

Looks a routine up by the interpretations of its written name and, when the call site keys it with one, the argument count (null for a name-only lookup).

lookup

public RoutineLookupResult lookup(List<RoutineName> interpretations,
                                  Integer argumentCount,
                                  CatalogObjectKind wanted,
                                  Collection<Object> visibleScopes)

A lookup for a routine of wanted kind (ROUTINE when the call site does not say), seeing the local routines declared in visibleScopes (the routines enclosing the call); triggers are not callable.
