Method Detail

headers

public Client.ContentCallback headers(ResponseHeaders responseHeaders)

Description copied from interface: Client.ClientCallback

Callback method invoked when the HTTP response code and headers are available.

This method can only be invoked once per request.

This method will return a callback which can be used to stream the response content, if any. Once the response content has been exhausted, Client.ClientCallback.complete() should be called to indicate as such.

Note that should should be invoked before Client.ClientCallback.complete(), but need not be invoked before Client.ClientCallback.abort(Throwable)

Specified by:

headers in interface Client.ClientCallback

Parameters:

responseHeaders - The response headers

Returns:

A callback which can be used to stream the response content

abort

public void abort(Throwable t)

Description copied from interface: Client.ClientCallback

Callback method invoked when the request fails for any reason. This will ultimately result in an exception being bubbled up to consumer code.

No other methods should be invoked on the callback after this is called (i.e. this is a terminal operation)

Specified by:

abort in interface Client.ClientCallback

Parameters:

t - The exception which caused the request to fail

complete

public void complete()

Description copied from interface: Client.ClientCallback

Called when the request completes successfully. Note that "successful" does not mean a 2xx response code, only that the client was able to successfully receive all data from the upstream server.

No other methods should be invoked on the callback after this is called (i.e. this is a terminal operation)

Specified by:

complete in interface Client.ClientCallback
