          public <V> void checkValid(V arg)
                              throws CredentialValidationException

      Description copied from interface: `Credentials`
      Implementors should override this method to perform validation. An argument is allowed to allow custom validation, for example, when given a configuration property, a specific property may be allowed to be null.
      Specified by:
        `checkValid` in interface `Credentials`
      Overrides:
        `checkValid` in class `UsernamePasswordCredentials`
      Type Parameters:
        `V` - the generic type of the argument
      Parameters:
        `arg` - optional argument or null.
      Throws:
        `CredentialValidationException` - when the validation fails

    - #### toJson

          public JsonObject toJson()

      Description copied from interface: `Credentials`
      Simple interop to downcast back to JSON for backwards compatibility.
      Specified by:
        `toJson` in interface `Credentials`
      Overrides:
        `toJson` in class `UsernamePasswordCredentials`
      Returns:
        JSON representation of this credential.

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `UsernamePasswordCredentials`

    - #### applyHttpChallenge

          public HtdigestCredentials applyHttpChallenge(String challenge,
                                                        HttpMethod method,
                                                        String uri,
                                                        Integer nc,
                                                        String cnonce)
                                                 throws CredentialValidationException

      Description copied from interface: `Credentials`
      Applies the HTTP Authorization challenge to this Credential instance. The internal state can change to reflect the extra properties the challenge conveys. See https://tools.ietf.org/html/rfc7235 for more information.
      Specified by:
        `applyHttpChallenge` in interface `Credentials`
      Overrides:
        `applyHttpChallenge` in class `UsernamePasswordCredentials`
      Parameters:
        `challenge` - the challenge is the `WWW-Authenticate` header response from a 401 request. Null challenges are allowed, and in this case, no verification will be performed, however it is up to the implementation to permit this.
        `method` - The http method this response is responding.
        `uri` - The http uri this response is responding.
        `nc` - The client internal counter (optional).
        `cnonce` - The client internal nonce (optional).
      Returns:
        fluent self.
      Throws:
        `CredentialValidationException` - if the challenge cannot be applicable.

    - #### toHttpAuthorization

          public String toHttpAuthorization()

      Description copied from interface: `Credentials`
      Encodes this credential as an HTTP Authorization https://tools.ietf.org/html/rfc7235. Calls to this method, expect that `Credentials.applyHttpChallenge(String, HttpMethod, String, Integer, String)` has been prior executed. For some Authentication schemes, this isn't a requirement but doing so ensures that the object is on the right state.
      Specified by:
        `toHttpAuthorization` in interface `Credentials`
      Overrides:
        `toHttpAuthorization` in class `UsernamePasswordCredentials`
      Returns:
        HTTP header including scheme.
