Constant-size queue?

[Gabe Moothart]

Hi,
I would like to use a System.Collecti ons.Queue which is constant size -
if it is full, it should fail to add new items instead of growing
automatically. I looked at the help, and thought that a growth factor of
1.0 would do this. However, it doesn't seem to have worked. Is there any
way to keep the queue from growing?

TIA,
Gabe

Re: Constant-size queue?

Hi,

There doesn't appear to be a way to do this through the existing interface.

Since the Enqueue method is virtual, you could create a derived class that
overrides this method and checks the size before passing the call down to the
base class.

Re: Constant-size queue?

These are sometimes called "bounded" queues. I did a bounded-blocking queue
here:

Blocking can be really helpful as your thread(s) can just block waiting for
some input or wait to write output without buzy loops or polling.
