Method Detail

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

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

Parameters:
