# POE::Resource::Extrefs(3pm)

internal reference counts manager for POE::Kernel

## NAME

POE::Resource::Extrefs - internal reference counts manager for POE::Kernel

## SYNOPSIS

There is no public API.

## DESCRIPTION

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 ALSO

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.

## BUGS

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.
