The ObjectAccessControl resource only has two modifiable fields: entity and role. This class allows application developers to setup a PATCH message, note that some of the possible PATCH messages may result in errors from the server, for example: while it is possible to express "change the value of the
entity field" with a PATCH request, the server rejects such changes.
