Checking PermissionsLocate this document in the navigation structure

Use

With the IPermission interface, you can do the following:

  • Check if a specific user has a specific permission - isAllowed() .

  • Get a list of all the permissions that can be assigned for this object - getAllPermissions() .

The interface also has the helper function getPermissionTitle() for getting the display name for a specific permission.

To modify permissions, use the PCD API, as described in Setting PCD Permissions .

Checking a User's Permission

The following code example checks whether the current user has read permission on the object with the PCD name stored in the string myObject :

               IAdminBase myAdmin = (IAdminBase)iCtx.lookup(myObject);
IPermission myIview = (IPermission)
    myAdmin.getImplementation(IAdminBase.PERMISSION);
         
boolean hasPermission = myIview
    .isAllowed(request.getUser(),IPermission.PCM_ADMIN_READ);
 
if (hasPermission) {
    response.write(request.getUser().getName() + " has " 
        + myIview.getPermissionTitle("Pcd.Read",request.getLocale())
            + " permission.<br>");     
}

Permission Constants

The IPermission interface provides constants for checking the following permissions:

  • Owner

  • Read

  • Write

  • Read-Write

  • Full Control

  • Use

To check the role assigner permission, use the constant IPortalBasicRoleFactoryService.ROLE_ASSIGNMENT_PERMISSION .

Note

The PCM's IPermission and PCD's IPcdStandardPermissions interfaces define different sets of permissions constants. They are not interchangeable.
