ACE_Bounded_Cached_Connect_Strategy Class Template Reference

A connection strategy which caches connections to peers (represented by <SVC_HANDLER> instances), thereby allowing subsequent re-use of unused, but available, connections. This strategy should be used when the cache is bounded by maximum size. More...

Detailed Description

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1, class CACHING_STRATEGY, class ATTRIBUTES, class MUTEX>
class ACE_Bounded_Cached_Connect_Strategy< SVC_HANDLER,, CACHING_STRATEGY, ATTRIBUTES, MUTEX >

A connection strategy which caches connections to peers (represented by <SVC_HANDLER> instances), thereby allowing subsequent re-use of unused, but available, connections. This strategy should be used when the cache is bounded by maximum size.

<Bounded_Cached_Connect_Strategy> is intended to be used as a plug-in connection strategy for <ACE_Strategy_Connector>. It's added value is re-use of established connections and tweaking the role of the cache as per the caching strategy. Thanks to Edan Ayal <edana@bandwiz.com> for contributing this class and Susan Liebeskind <shl@janis.gtri.gatech.edu> for brainstorming about it.
