prepareRequest

public BaseRestHandler.RestChannelConsumer prepareRequest(RestRequest request, NodeClient client) throws java.io.IOException

Description copied from class: BaseRestHandler

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:

request - the request to execute

client - client for executing actions on the local node

Returns:

the action to execute

Throws:

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