// Class : QueuedConnectionReader

|
// Description : This flavor of ConnectionReader will read from its
|
|
// sockets and queue up all of the datagrams read for
|
|
// later receipt by the client code. This class is
|
|
// useful for client code that doesn't want to deal with
|
|
// threading and is willing to poll for datagrams at its
|
|
// convenience.
