Examples of org.apache.ace.agent.DownloadHandle

org.apache.ace.agent.DownloadHandle
A {@link DownloadHandle} provides control over an asynchronous download and access to the resulting file when the itis completed.

Consumers must consider the following rules;
- Control methods must be called in logical order.
- Implementations are not expected to be thread-safe.
- Resulting files must be assumed to be transient.


            DefaultController controller = getController();
            controller.logInfo("Starting download of %s update, %s => %s...", m_type, updateInfo.m_from, updateInfo.m_to);


            try {
                DownloadHandle downloadHandle = delegate.getDownloadHandle(updateInfo.m_to, updateInfo.m_fixPackage);


                try {
                    Future<DownloadResult> future = downloadHandle.start(this);
                    DownloadResult downloadResult = future.get();


                    if (downloadResult.isComplete()) {
                        controller.logInfo("Installing %s update %s => %s...", m_type, updateInfo.m_from, updateInfo.m_to);


                        startInstallation(updateInfo);


                        delegate.install(downloadResult.getInputStream());


                        installationSuccess(updateInfo);


                        // Clean up any temporary files...

                }
