App::Standby::Service - Service Plugin baseclass
The name of this plugin. SHOULD be lowercase. SHOULD also used as a key prefix in the config table.
A human readable description of this service plugin. Used for display and logging. MAY be empty.
The numeric group id of the group this service plugins instance is associated with. MUST be numeric and MUST NOT be empty.
This method is called with a array_ref containing the new ordering on any changed.
First of all there are two kinds of services: Simple HTTP endpoints and complex plugins.
The simple HTTP plugins just receive the whole queue in as JSON encoded array. Those only need to subclass App::Standby::Service::HTTP and provide an implementation for _init_endpoints. Have a look at the simple example.
All other services will need to subclass App::Standby::Service and implement an update() method. Have a look at App::Standby::Service::Pingom for an example.
The method _config_values helps with getting values to known keys from the config table. A service plugin MUST always prepend its name to the key to allow for multiple instances of one plugin registered at the same time.
