Client transport connector extension contract.
Note that unlike most of the other Jersey SPI extension contracts
, Jersey Connector
is not a typical runtime extension and as such cannot be directly registered using a configuration register(...)
method. Jersey client runtime retrieves a Connector
instance upon Jersey client runtime initialization using a ConnectorProvider
registered in ClientConfig
.

Synchronously process client request into a response.
The method is used by Jersey client runtime to synchronously send a request
and receive a response.
Params: - request – Jersey client request to be sent.
Throws: - ProcessingException – in case of any invocation failure.
Returns: Jersey client response received for the client request.

Params: - request – Jersey client request to be sent.
- callback – Jersey asynchronous connector callback to asynchronously receive
the request processing result (either a response or a failure).
Returns: asynchronously executed task handle.

Returns: name of current connector. Returning null
