Inherits from:Networking.DownloadHandler

Switch to Manual


An abstract base class for user-created scripting-driven DownloadHandler implementations.

On its own, a DownloadHandlerScript object does no useful work.

Instead, it forwards data received from the network to the DownloadHandler.ReceiveData callback method, as well as invoking other useful callbacks for download-related events. By default, a DownloadHandlerScript does nothing; however, you can derive your own subclass from DownloadHandlerScript, override some or all of its callbacks and thereby implement completely custom data handling.

See Also: DownloadHandler.ReceiveData, DownloadHandler.ReceiveContentLength, DownloadHandler.CompleteContent.


DownloadHandlerScriptCreate a DownloadHandlerScript which allocates new buffers when passing data to callbacks.
