Custom Internal Adapters

For circumstances where the supplied adapters do not meet your needs, Event Stream Processor provides an internal adapter framework you can use to build internal adapters.

• The Adapter Shared Utility Library
  The adapter shared utility library provides the utility functions required for a custom adapter implementation, including data conversion, data manipulation, and data management.
• Callback Functionality
  An adapter implementation can use callback functions to log on to the Server, retrieve information related to schemas, and convey state information to the Server.
• Sample Model File
  Sample syntax you can use to build a basic model file.
• The Adapter Configuration File
  The internal adapter configuration file is an XML file (.cnxml) that contains the properties and commands used by Event Stream Processor to start and stop the internal adapter, as well as other information that allows the internal adapter to be configured from the Studio.
• Adapter Life Cycle Functions
  All adapters follow a set of adapter life cycle events.
• Adapter Setup Functions
  The Server uses information management functions to complete the adapter implementation process.
• Miscellaneous Functions
  Describes miscellaneous APIs supported for Event Stream Processor adapters.
• Adapter Run States
  Adapters progress through a set of run states (RS) as they interact with Event Stream Processor.
• Schema Discovery for Internal Custom Adapters
  Use extern "C" functions to enable your custom internal adapter for schema discovery.
• Sample Custom Internal Adapter Implementation
  Sample syntax you can use to build your custom internal adapter implementation.This implementation incorporates extern "C" methods that enable schema discovery in a custom adapter.
