### commit

boolean commit()
Commit this update. If no changes have been made to the Conditional Permission Table since this update was created, then this method will replace the Conditional Permission Table with this update's Conditional Permissions. This method may only be successfully called once on this object.

If any of the `ConditionalPermissionInfo`s in the update list has `null` as a name it will be replaced with a new `ConditionalPermissionInfo` object that has a generated name which is unique within the list.

No two entries in this update's Conditional Permissions may have the same name. Other consistency checks may also be performed. If this update's Conditional Permissions are determined to be inconsistent in some way then an `IllegalStateException` will be thrown.

This method returns `false` if the commit did not occur because the Conditional Permission Table has been modified since the creation of this update.

  `true` if the commit was successful. `false` if the commit did not occur because the Conditional Permission Table has been modified since the creation of this update.
Throws:
  `SecurityException` - If the caller does not have `AllPermission`.
