All adapters follow a set of adapter life cycle events.
| API | Description |
|---|---|
| bool reset(void* adapters); | Initializes both input and output adapters. |
| void start(void* adapter); | Processes data that is specific to the adapter implementation. Call this API immediately after resetting both input and output adapters. |
| void* getNext(void* adapter); | Reads data and returns a pointer to the data in a format the ESP Server understands. The adapter shared utility library provides data conversion functions. Call this API for input adapters only. |
| void putNext(void* adapter,void* stream); | Converts presented data into a format the ESP Server understands, and writes it according to the specified adapter implementation. The adapter shared utility library provides data conversion functions. Call this API for output adapters only. |
| void stopRequested(void* adapter); | Sets a flag to indicate that a request has been sent to stop the adapter. Call this API for both input and output adapters. |
| void stop(void* adapter); | Stops an adapter. Call this API for both input and output adapters. |
| void cleanup(void* adapter); | Performs cleanup activities after an adapter is stopped. |
| void commitTransaction(void* adapter); | Notifies an output adapter when a transaction ends and pushes any buffered data into the target. Call this API for output adapters only. |
| void putStartSync(void* adapter); | Notifies the adapter implementation that the base data is being sent. Call this API for output adapters only. |
| void putEndSync(void* adapter); | Notifies the adapter implementation that the base data has been sent. Call this API for output adapters only. |
| void purgePending)void* adapter); | Instructs an output adapter to purge pending data. Call this API for output adapters only. |
| bool isOutBase(void* adapter); | Determines whether the adapter expects to receive the output for the base contents of the stream. Call this API for output adapters only. |
