Example 36 with InvalidArgumentException

use of javax.sip.InvalidArgumentException in project XobotOS by xamarin.

the class PPreferredServiceParser method parse.

/**
     * "The URN consists of a hierarchical service identifier or application
     * identifier, with a sequence of labels separated by periods.The left-most label is
     * the most significant one and is called 'top-level service
     * identifier', while names to the right are called 'sub-services' or
     * 'sub-applications'.
     *
     * For any given service identifier, labels can be removed right-to-left and
     * the resulting URN is still valid, referring a more generic
     * service, with the exception of the top-level service identifier
     * and possibly the first sub-service or sub-application identifier.
     *
     *  Labels cannot be removed beyond a defined basic service, for
     *  example, the label w.x may define a service, but the label w may
     *  only define an assignment authority for assigning subsequent
     *  values and not define a service in its own right.  In other words,
     *  if a service identifier 'w.x.y.z' exists, the URNs 'w.x' and
     *  'w.x.y' are also valid service identifiers, but w may not be a
     *  valid service identifier if it merely defines who is responsible"
     *
     * TODO: PLEASE VALIDATE MY UNDERSTANDING OF THE ABOVE TEXT :)
     * @ranga: Please validate my understanding of the above text in the draft :)
     *         This last para is a little ambiguous.I will only check that atleast
     *         1 sub-service or 1 sub-application is present in the URN declaration.
     *         If not, I throw an exception. I thought of not throwing an exception
     *         and returning whatever was encoded..but the resultant encoding wont
     *         make sense. It would be something like-->
     *         urn:urn-7:3gpp-service OR urn:urn-7:3gpp-application alone with no sub-services
     *         or sub-applications. This is bound to cause an error at the recepient later.
     *
     * Sub-service and Application identifiers are not maintained by IANA and
     * are organization/application dependent (Section 8.2). So we cannot gurantee what lies
     * beyond the first sub-service or sub-application identifier. It should be the responsibility
     * of the application to make sense of the entire URN holistically. We can only check for the
     * standardized part as per the ABNF.
