UserAccess

SAIF.Application.UserAccess is the library's abstract authorization helper. It delegates resource checks to clsSecurityPrincipal and caches the outcome for each resource name.

Purpose

• Provide reusable resource-authorization checks for callers that work with clsSecurityPrincipal.
• Avoid repeated authorization calls for the same resource name during the lifetime of a UserAccess instance.

Context

• Namespace: SAIF.Application
• Assembly/package: SAIF.BOF.Application

Public members

Member	Signature	Purpose
HasAccess	Public Function HasAccess(ByVal inResourceName As String) As Boolean	Return True if the user has access to the resource; on first check, delegate to clsSecurityPrincipal.IsAuthorized and cache the result keyed by lower-cased resource name for subsequent lookups.
CheckAccess	Public Sub CheckAccess(ByVal ParamArray inResourceName As String())	Evaluate one or more AD resource names through HasAccess, populating the internal access-control cache for each name (the per-call return value is discarded).

Behavioral notes

• This type implements the per-resource cache behavior documented in BR-003.
• Resource names are supplied by callers at runtime rather than defined as literals in this library.

Constraints and usage notes

• This type is abstract and depends on a supplied clsSecurityPrincipal instance.
• The helper addresses authorization reuse; it does not define AD resource names or role catalogs itself.
