  • Method Details

    • preValidate

      public void preValidate() throws MessageException
      Description copied from class: Message
      Performs initial validation of a message to include validation of AVPs required to determine if the request/answer should be forwarded. If we determine the message should be handled locally, then the remaining AVPs will be validated by 'validate()'.
      Overrides:
      preValidate in class Message
      Throws:
      MessageException - if validation failed

    • preValidateAvp

      protected void preValidateAvp(Avp avp) throws AvpException
      Description copied from class: Message
      Fully decodes and validates the specified AVP. Message implementations can override this to provide additional validation or to cache AVP results.
      Overrides:
      preValidateAvp in class Message
      Parameters:
      avp - the AVP to be validated
      Throws:
      AvpException - if the AVP was invalid

    • getResultCode

      public ResultCode getResultCode()
      Returns the ResultCode for this answer. This corresponds to either the Result-Code AVP or Experimental-Result AVP.

    • setResultCode

      public void setResultCode(ResultCode rc)
      Allows relay or proxy applications to modify result code of an answer message being forwarded. This is only possible if existing result code value does not already indicate an error. If result code is changed, and this host is different from the origin-host, then set the Error-Reporting-Host AVP as well. See RFC 3588 section 6.2.2 for more details.
