ResourcePool::Resource - A ResourcePool wrapper class for a resource
use ResourcePool::Resource; my $resource = ResourcePool::Resource->new();
This class is a base class for the resources which will be used with ResourcePool. ResourcePool uses this class internally to have a unique interface to interact with the resource.
Each ResourcePool::Resource class gets constructed by the corresponding ResourcePool::Factory class. In fact the Factory classes are just used to store the parameters which are required to construct a resource.
Every class which is derived from ResourcePool::Resource must override the close, fail_close and get_plain_resource methods and should override at least one of precheck or postcheck.
