These helpers do not implement any MIB objects themselves. Rather they handle specific generic situations, either returning an error, or passing a (possibly simpler) request down to lower level handlers.

Modules |
|
| group | bulk_to_next: convert GETBULK requests into GETNEXT requests for the handler. |
| The only purpose of this handler is to convert a GETBULK request to a GETNEXT request. |
|
| group | cache_handler: Maintains a cache of data for use by lower level handlers. |
| This helper checks to see whether the data has been loaded "recently" (according to the timeout for
that particular cache) and calls the registered "load_cache" routine if necessary. |
|
| group | debug: print out debugging information about the handler chain being called. |
| This is a useful module for run-time debugging of requests as the pass this handler in a calling
chain. |
|
| group | mode_end_call: at the end of a series of requests, call another handler hook. |
| Handlers that want to loop through a series of requests and then receive a callback at the end of a
particular MODE can use this helper to make this possible. |
|
| group | multiplexer: splits mode requests into calls to different handlers. |
| The multiplexer helper lets you split the calling chain depending on the calling mode (get vs
getnext vs set). |
|
| group | read_only: make your handler read_only automatically |
| The only purpose of this handler is to return an appropriate error for any requests passed to it in
a SET mode. |
|
| group | row_merge: Calls sub handlers with request for one row at a time. |
| This helper splits a whole bunch of requests into chunks based on the row index that they refer to,
and passes all requests for a given row to the lower handlers. |
|
| group | serialize: Calls sub handlers one request at a time. |
| This functionally passes in one request at a time into lower handlers rather than a whole bunch of
requests at once. |
|
| group | stash_to_next: convert GET_STASH requests into GETNEXT requests for the handler. |
| The purpose of this handler is to convert a GET_STASH auto-cache request to a series of GETNEXT
requests. |
