Introduction

The topic stream delegate protocol defines the methods to be implemented by classes wishing to receive streamed topic updates.

Deprecated:: Since 6.0. Topic streams are only necessary to support the deprecated stateless and record topic types. They will be removed along with these topic types in a future release.
