Apache Collections -- BoundedFifoBuffer

[Jerry]

I am using BoundedFifoBuffer from Apache Collection to enqueue and
dequeue Minute object (I defined this object). I find there is no
contructor in BoundedFifoBuffer that I can pass a Comparator object.

If I don't pass a Comparator object, "contains" method in
BoundedFifoBuffer won't work. It doesn't know if a Minute object is in
the queue.

Anyone knows how to solve this problem?

Thanks a lot!

First of all you have to implement "equals" rather than use Comparator
because BoundedFifoBuffer implementation of "contains" is based on
"equals".
Moreover there is no need to use Comparator in this context.
