/**

|
* @class ACE_FlReactor
|
|
*
|
|
* @brief A Reactor implementation that uses the Fast-Light (FL) toolkit
|
|
* for event demultiplexing. This will let us integrate the FL
|
|
* toolkit with ACE and/or TAO.
|
|
*
|
|
* As many other GUI toolkits FL supports a minimal set of
|
|
* callbacks to handle event demultiplexing, namely simple methods
|
|
* to add file descriptors to the event demuxing set or timeout
|
|
* events. This class adapts this simple mechanisms so they are
|
|
* compatible with ACE's Reactor.
