An abstract Cronet callback that reads the entire body to memory and optionally deserializes the body before passing it back to the issuer of the HTTP request.

The requester can subscribe for updates about the request by adding completion mListeners on the callback. When the request reaches a terminal state, the mListeners are informed in order of addition.

## Public Methods

#### public[ImplicitFlowControlCallback](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/apihelpers/ImplicitFlowControlCallback.html)**addCompletionListener**([CronetRequestCompletionListener](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/apihelpers/CronetRequestCompletionListener.html)\<? super T\> listener)

Adds a completion listener. All listeners are informed when the request reaches a terminal state, in order of addition. If a listener is added multiple times, it will only be called once according to the first time it was added.  

##### Parameters

| listener |   |
|----------|---|

## Protected Methods

#### protected final void**onBodyChunkRead**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info, ByteBuffer bodyChunk)

Invoked whenever part of the response body has been read. Only part of the buffer may be populated, even if the entire response body has not yet been consumed. The buffer is ready for reading. Buffers are reused internally so the implementing class shouldn't store the buffer or use it anywhere else than in the implementation of this method.  

##### Parameters

|   info    |                      Response information.                       |
| bodyChunk | The buffer that contains the received data, flipped for reading. |
|-----------|------------------------------------------------------------------|

##### Throws

| Exception |   |
|-----------|---|

#### protected final void**onCanceled**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info)

Invoked if request was canceled via[UrlRequest.cancel()](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlRequest.html#cancel()). Once invoked, no other[UrlRequest.Callback](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlRequest.Callback.html)methods will be invoked.  

##### Parameters

| info | Response information. May be`null`if no response was received. |
|------|----------------------------------------------------------------|

#### protected final void**onFailed**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info,[CronetException](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/CronetException.html)exception)

Invoked if request failed for any reason after[UrlRequest.start()](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlRequest.html#start()). Once invoked, no other[UrlRequest.Callback](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlRequest.Callback.html)methods will be invoked.`error`provides information about the failure.  

##### Parameters

|   info    | Response information. May be`null`if no response was received. |
| exception |                    information about error.                    |
|-----------|----------------------------------------------------------------|

#### protected final void**onResponseStarted**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info)

Invoked when the final set of headers, after all redirects, is received. Will only be invoked once for each request. It's guaranteed that Cronet doesn't start reading the body until this method returns.  

##### Parameters

| info | Response information. |
|------|-----------------------|

#### protected final void**onSucceeded**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info)

Invoked when request is completed successfully. Once invoked, no other[UrlRequest.Callback](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlRequest.Callback.html)methods will be invoked.  

##### Parameters

| info | Response information. |
|------|-----------------------|

#### protected abstract T**transformBodyBytes**([UrlResponseInfo](https://developer.android.com/develop/connectivity/cronet/reference/org/chromium/net/UrlResponseInfo.html)info, byte\[\] bodyBytes)

Transforms (deserializes) the plain full body into a user-defined object.

It is assumed that the implementing classes handle edge cases (such as empty and malformed bodies) appropriately. Cronet doesn't inspects the objects and passes them (or any exceptions) along to the issuer of the request.  

##### Parameters

|   info    |   |
| bodyBytes |   |
