POE::Resource::Extrefs - internal reference counts manager for POE::Kernel
POE::Resource::Extrefs is a mix-in class for POE::Kernel. It provides the
features to manage session reference counts, specifically the ones that
applications may use. POE::Resource::Extrefs is used internally by
POE::Kernel, so it has no public interface.
See "Public Reference Counters" in POE::Kernel for the public extref
API.
See "Resources" in POE::Kernel for public information
about POE resources.
See POE::Resource for general discussion about resources and the
classes that manage them.
Reference counters have no ownership information, so one entity's reference
counts may conflict with another's. This is usually not a problem if all
entities behave.
