Permissions
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.
In order to modify permissions, use the PCD API, as described in 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 IPermissioninterface 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.
The PCM’s IPermission and PCD’s IPcdStandarPermissions interfaces define different sets of permissions constants. They are not interchangeable.
