POE::XS::Queue::Array - an XS implementation of POE::Queue::Array.
This class is an implementation of the abstract POE::Queue interface. It implements a priority queue using C, with an XS interface supplied.
The current implementation could use some optimization, especially for large queues.
Please see the POE::Queue documentation, which explains this one's functions, features, and behavior.
The following extra methods are added beyond POE::Queue::Array:
Dumps the internal structure of the queue to stderr.
Does limited verification of the structure of the queue. If the verification fails then a message is sent to stderr and the queue is dumped as with the dump() method, and your program will exit.
POE, POE::Queue, POE::Queue::Array
Some possible improvements include:
use a B-Tree for the queue (not a binary tree, a B-Tree), though this would require a module rename.
use a custom hash instead of a HV for the id to priority mapping, either glib's hash or convert to C++ and use the STL map.
some of the XS code could be optimized to do less work in scalar context, pq_remove_items and pq_peek_items could avoid building all those array refs.
POE::XS::Queue::Array is licensed under the same terms as Perl itself.
