Type Parameters:

I - The request body type

O - The response body type

E - The error type

Parameters:

request - The HttpRequest to execute

bodyType - The body type

errorType - The error type

Returns:

The full HttpResponse object

isRunning

public boolean isRunning()

Specified by:

isRunning in interface LifeCycle<BlockingHttpClient>

Returns:

Whether the component is running

start

public BlockingHttpClient start()

Description copied from interface: LifeCycle

Starts the lifecyle component.

Specified by:

start in interface LifeCycle<BlockingHttpClient>

Returns:
