onClose(int statusCode, HttpJsonMetadata trailers)

public void onClose(int statusCode, HttpJsonMetadata trailers)

The ClientCall has been closed. Any additional calls to the ClientCall will not be processed by the server. No further receiving will occur and no further notifications will be made.

This method should not throw. If this method throws, there is no way to be notified of the exception. Implementations should therefore be careful of exceptions which can accidentally leak resources.
