RE: dqGOOP beta

[Jim K. <jim...@ja...>]

Brian,

First, let me say that this is a very nice and GOOP implementation.  It is
very clever how you get the mutex/semaphore-like behavior "for free" with
the "Dequeue Element" function waiting for an element to be queued.  Also,
how the "Preview Queue Element" function allows reading the data store (when
one is not intending to write data).  However, there is one behavioral
difference b/w the dqGOOP and traditional semaphored data, which you might
have noticed -- a call to "Get Data" will wait until a data modifying member
function has written the data.  Basically the "Get Data" and "Get Data to
Modify" will both wait until "Set Modified Data" is called, since "Preview
Queue Element" cannot return until there is an element on the queue, which
will not occur while data is in the process of being modified.  I don't
think that this is a big deal for most (if any) applications, but it is a
difference worth mentioning.

Cheers,

-Jim Kring
