Method Detail

getName

public java.lang.String getName()

Specified by:

getName in class BaseRestHandler

Returns:

the name of this handler. The name should be human readable and should describe the action that will performed when this API is called. This name is used in the response to the RestNodesUsageAction.

prepareRequest

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

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
