protected BaseRestHandler.RestChannelConsumer prepareRequest(RestRequest restRequest,
 NodeClient client)
                                                      throws IOException

Description copied from class: BaseRestHandler

Prepare the request for execution. Implementations should consume all request params before returning the runnable for actual execution. Unconsumed params will immediately terminate execution of the request. However, some params are only used in processing the response; implementations can override BaseRestHandler.responseParams() to indicate such params.

Specified by:

prepareRequest in class BaseRestHandler

Parameters:

restRequest - the request to execute

client - client for executing actions on the local node

Returns:

the action to execute

Throws:

IOException - if an I/O exception occurred parsing the request and preparing for execution
