module Discordrb::EventContainer
This module provides the functionality required for events and awaits. It is separated from the {Bot} class so users can make their own container modules and include them.
Public Class Methods
Utility method to return a class object from a string of its name. Mostly useful for internal stuff @param str [String] The name of the class @return [Class] the class
# File lib/discordrb/container.rb, line 545 def self.class_from_string(str) str.split('::').inject(Object) do |mod, class_name| mod.const_get(class_name) end end
Returns the event class for a handler class type @see handler_class @param handler_class
[Class] The handler type @return [Class, nil] the event type, or nil if the handler_class
isn't a handler class (i.e. ends with Handler)
# File lib/discordrb/container.rb, line 535 def self.event_class(handler_class) class_name = handler_class.to_s return nil unless class_name.end_with? 'Handler' EventContainer.class_from_string(class_name[0..-8]) end
Returns the handler class for an event class type @see event_class @param event_class
[Class] The event type @return [Class] the handler type
# File lib/discordrb/container.rb, line 527 def self.handler_class(event_class) class_from_string(event_class.to_s + 'Handler') end
Public Instance Methods
Adds an event handler to this container. Usually, it's more expressive to just use one of the shorthand adder methods like {#message}, but if you want to create one manually you can use this. @param handler [Discordrb::Events::EventHandler] The handler to add.
# File lib/discordrb/container.rb, line 503 def add_handler(handler) clazz = EventContainer.event_class(handler.class) @event_handlers ||= {} @event_handlers[clazz] ||= [] @event_handlers[clazz] << handler end

This event is raised when the bot has disconnected from the WebSocket
, due to the {Bot#stop} method or external causes. It's the recommended way to do clean-up tasks. @param attributes [Hash] Event attributes, none in this particular case @yield The block is executed when the event is raised. @yieldparam event [DisconnectEvent] The event that was raised. @return [DisconnectEventHandler] the event handler that was registered.

This event is raised every time the bot sends a heartbeat over the galaxy. This happens roughly every 40 seconds, but may happen at a lower rate should Discord change their interval. It may also happen more quickly for periods of time, especially for unstable connections, since discordrb rather sends a heartbeat than not if there's a choice. (You shouldn't rely on all this to be accurately timed.)
All this makes this event useful to periodically trigger something, like doing some API
request every hour, setting some kind of uptime variable or whatever else. The only limit is yourself. @param attributes [Hash] Event attributes, none in this particular case @yield The block is executed when the event is raised. @yieldparam event [HeartbeatEvent] The event that was raised. @return [HeartbeatEventHandler] the event handler that was registered.
