Method Detail

hasPermission

public boolean hasPermission(Permission p)

Description copied from interface: AccessController

Does the current Subject have the permission? It is up to the access controller implementation to know how to find the current subject. Most implementations will use some kind of ThreadLocal to store the subject.

The AccessController.checkPermission(Permission) method performs the same checks as this method, but throws an AccessDeniedException if the subject does not have the requested permission.

Parameters:

p - The permission. When EntityFS methods are calling this method, this is always an EntityPermission.

Returns:

true if the subject has the permission, false if not.

isEnabled

public boolean isEnabled()

Description copied from interface: AccessController

Check if the AccessController is enabled. A disabled access controller grants all access requests.

Returns:

true if this access controller is enabled.
