continuous

Asynchronously invoke this but expect a continuous stream of content.

This means that the body data will not be accumulated and thus you cannot use get_payload

When there is data callback will be called and when the connection is closed or the stream ends callback will also be called.

If weak_object is disposed during the call then this call will be cancelled. If the call is cancelled then the callback will be invoked with an error state.

You may unref the call after calling this function since there is an internal reference, or you may unref in the callback.

Parameters:

this	The ProxyCall
callback	a ProxyCallContinuousCallback to invoke when data is available
weak_object	The Object to weakly reference and tie the lifecycle to
userdata	data to pass to callback
