 * implementation.
 * - `outputParser` - Used to parse the output value before it is sent to the client on your `AdapterQuery`
 * implementation.
 * - `translate` - Used to translate the CharField to something that the database can understand.
 * translated directly with the `translate` method, all other field types should define a parser with the `translate`
 * field, those will be injected in the `DatabaseAdapter` class constructor.
