    All Methods Static Methods Instance Methods Abstract Methods Default Methods
    Modifier and Type | Method and Description
    --- | ---
    `<V> void` | `checkValid(V arg)` Implementors should override this method to perform validation.
    `Credentials` | `getDelegate()`
    `static Credentials` | `newInstance(Credentials arg)`
    `JsonObject` | `toJson()` Simple interop to downcast back to JSON for backwards compatibility.
