Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`protected class`	`Nio2Endpoint.Acceptor` With NIO2, the main acceptor thread only initiates the initial accept but periodically checks that the connector is still accepting (if not it will attempt to start again).
`static interface`	`Nio2Endpoint.Handler` Bare bones interface used for socket processing.
`static class`	`Nio2Endpoint.Nio2SocketWrapper`
`static class`	`Nio2Endpoint.NioBufferHandler`
`static class`	`Nio2Endpoint.SendfileData` SendfileData class.
`protected class`	`Nio2Endpoint.SocketProcessor` This class is the equivalent of the Worker, but will simply use in an external Executor thread pool.
