POE::Resource - internal resource managers for POE::Kernel
Varies, although most POE::Resource subclasses do not have public APIs.
POE manages several types of information internally. Its Resource classes are mix-ins designed to manage those types of information behind
tidy, mostly private interfaces. This was done to facilitate testing and a conversion to C without the need to port POE::Kernel all at
POE::Resource subclasses are generally different from one another, but there are some similarities to note.
Every resource should have an initializer and finalizer method. Initializers set up initial data and link resources into POE::Kernel.
Finalizers clean up any remaining data and verify that each resource subsystem was left in a consistent state.
One common theme in resource implementations is that they don't need to perform much error checking, if any. Resource methods are used
internally by POE::Kernel and/or POE::API classes, so it's up to them to ensure correct usage.
Resource methods follow the naming convention _data_???_activity, where ??? is an abbreviation for the type of resource it belongs to:
Finalizer methods end in "_finalize".
Finalizers return true if a resource shut down cleanly, or false if there were inconsistencies or leaks during end-of-run checking. The
t/res/*.t tests rely on these return values.
POE::Resource::Aliases, POE::Resource::Events, POE::Resource::Extrefs, POE::Resource::FileHandles, POE::Resource::SIDs,
Also see "Resources" in POE::Kernel for for public information about POE resources.
