IABACPolicies.IndexOf

Syntax

IndexOf(Value: IABACPolicy): Integer;

IndexOf(Prognoz.Platform.Interop.ABAC.IABACPolicy): System.Int32;

Parameters

Value. Policy value.

Description

The IndexOf method returns policy index in attribute-based access control structure.

Comments

If the specified policy is not found, the method returns -1.

Policies indexing starts from zero.

To get element of attribute-based access control structure by its index, use the IABACPolicies.Item property.

Example

To execute the example, make sure that attribute-based access control contains a policies set with two nested policies.

To execute the example, add links to the ABAC, Metabase, ForeSystem (for the Fore.NET example) system assemblies.

After executing the example, the console displays the message:

Test policy

Index = 2
