Class LocalScopes

Object

gudusoft.gsqlparser.dlineage.symbol.LocalScopes

public final class LocalScopes
extends Object

The scope a local symbol is declared in: the declaring routine's written name as frozen when the routine was declared (its model's display key, defaults included), prefixed by its package's; null at top level. It is found by the walk DlineageUtil.getProcedureParentName makes (the statement itself when it is a named routine, else the enclosing one, a block's owner included), but read from the routine's model, never re-composed from text with the session's defaults of the moment.

Method Summary

Modifier and Type	Method and Description
static List<Object>	chainOf(ModelBindingManager manager, TCustomSqlStatement stmt) The scopes a statement's references see, innermost first: its routine's, the enclosing routines' (nested routines), then the package's.
static TCustomSqlStatement	routineOf(TCustomSqlStatement stmt) The routine statement a statement's local symbols belong to, or null at top level.
static Object	scopeOf(ModelBindingManager manager, Procedure procedure) The frozen scope of a routine model: its display key, qualified by its package's; a routine declared inside another routine is scoped inside that routine's scope, so same-named nested routines of two routines are two scopes.
static Object	scopeOf(ModelBindingManager manager, TCustomSqlStatement stmt) The scope of a statement's local symbols: its routine's frozen scope; a package's own key for declarations at package level (a package is a named routine statement with no routine model); null at top level.

Method Detail

routineOf

public static TCustomSqlStatement routineOf(TCustomSqlStatement stmt)

The routine statement a statement's local symbols belong to, or null at top level.

scopeOf

public static Object scopeOf(ModelBindingManager manager,
                             Procedure procedure)

The frozen scope of a routine model: its display key, qualified by its package's; a routine declared inside another routine is scoped inside that routine's scope, so same-named nested routines of two routines are two scopes.

chainOf

public static List<Object> chainOf(ModelBindingManager manager,
                                   TCustomSqlStatement stmt)

The scopes a statement's references see, innermost first: its routine's, the enclosing routines' (nested routines), then the package's. Never the top level: a routine body does not see a batch's or an anonymous block's variables. Empty at top level.

scopeOf

public static Object scopeOf(ModelBindingManager manager,
                             TCustomSqlStatement stmt)

The scope of a statement's local symbols: its routine's frozen scope; a package's own key for declarations at package level (a package is a named routine statement with no routine model); null at top level.
