      • createQuotePublisher

        public SubjectMessagePublisher<RateSubjectInfo> createQuotePublisher​(String namespace,
                                                                             CachedDataProvider<RateSubjectInfo> provider,
                                                                             boolean sendDiscardAfterError)
        Creates an MMQuotePublisher that is able to respond to messages received on the CachedDataProvider that is passed in.
        Parameters:
        namespace - the namespace to provide rates for, defaults are defined in RateSubjectNamespacing.DefaultNamespaces
        provider - the CachedDataProvider that will receive the rate requests
        sendDiscardAfterError - If set to TRUE, your CachedDataProvider will receive an immediate callback on the CachedDataProvider.onDiscard(SubjectInfo) method after you publish a failure message by calling SubjectMessagePublisher.sendNotFound(SubjectInfo). This can be useful if you want to use the same code path to clear a cache (for example) whether a subscription is ended by the client discarding it or the back end you are integrating with no longer providing the data.
        Returns:
        the MMQuotePublisher able to send quotes containing rates
      • createQuotePublisherWithSubjectParser

        Creates an MMQuotePublisher that is able to respond to messages received on the CachedDataProvider that is passed in.
        Parameters:
