PTDiffusionMissingTopicNotification Class Reference

Introduction

Notification that a session has made a request using a selector that does not match any topics.

Processing of the initial request will be halted until proceed is called, at which point the selector will be resolved against the topic tree again.

If after calling proceed the selector still does not match against any topics, no further notifications will be provided.

Should cancel be called, or the notification time out, the request will be discarded. The requesting session will not be notified that their request has been cancelled.
