Interface PermissionFactory

public interface PermissionFactory

PermissionFactory defines the interface for a class that can create Permission instances based on:

• a permission type
• a resource pattern
• a list of actions
• and either an AccessControlRule or a SecurityDomain name

The resources matching a Permission are either protected by an AccessControlRule or by another SecurityDomain to which access control is delegated. Thus, a PermissionFactory provides factory methods to create either flavor of Permission.
