- * AsyncSocket defines an asynchronous API for streaming I/O.
- *
- * This class provides an API to for asynchronously waiting for data
- * on a streaming transport, and for asynchronously sending data.
- *
- * The APIs for reading and writing are intentionally asymmetric. Waiting for
- * data to read is a persistent API: a callback is installed, and is notified
- * whenever new data is available. It continues to be notified of new events
- * until it is uninstalled.
- *
- * AsyncSocket does not provide read timeout functionality, because it
- * typically cannot determine when the timeout should be active. Generally, a
- * timeout should only be enabled when processing is blocked waiting on data
- * from the remote endpoint. For server-side applications, the timeout should
- * not be active if the server is currently processing one or more outstanding
- * requests on this transport. For client-side applications, the timeout
- * should not be active if there are no requests pending on the transport.
- * Additionally, if a client has multiple pending requests, it will ususally
- * want a separate timeout for each request, rather than a single read timeout.
- *
- * The write API is fairly intuitive: a user can request to send a block of
- * data, and a callback will be informed once the entire block has been
- * transferred to the kernel, or on error. AsyncSocket does provide a send
- * timeout, since most callers want to give up if the remote end stops
- * responding and no further progress can be made sending the data.
