Subscription

Subscriptions are used in the callback for an Observable. Standard usage is as follows.

-- Constucts an observable which will emit a, b, c via a subscription
Observable.new(function(sub)
	sub:Fire("a")
	sub:Fire("b")
	sub:Fire("c")
	sub:Complete() -- ends stream
end)

Functions

new

Subscription.new(
fireCallbackfunction?,
failCallbackfunction?,
completeCallbackfunction?,
observableSourcestring?
) → Subscription

Constructs a new Subscription

Fire

Subscription:Fire(...any) → ()

Fires the subscription

Fail

Subscription:Fail() → ()

Fails the subscription, preventing anything else from emitting.

GetFireFailComplete

Subscription:GetFireFailComplete() → (
function,
function,
function
)

Returns a tuple of fire, fail and complete functions which can be chained into the the next subscription.

return function(source)
	return Observable.new(function(sub)
		sub:Fire("hi")

		return source:Subscribe(sub:GetFireFailComplete())
	end)
end

GetFailComplete

Subscription:GetFailComplete() → (
function,
function
)

Returns a tuple of fail and complete functions which can be chained into the the next subscription.

return function(source)
	return Observable.new(function(sub)
		return source:Subscribe(function(result)
			sub:Fire(tostring(result))
		end, sub:GetFailComplete()) -- Reuse is easy here!
	end)
end

Complete

Subscription:Complete() → ()

Completes the subscription, preventing anything else from being emitted.

IsPending

Subscription:IsPending() → boolean

Returns whether the subscription is pending.

Destroy

Subscription:Destroy() → ()

Cleans up the subscription

tip

This will be invoked by the Observable automatically, and should not be called within the usage of a subscription.

Disconnect

Subscription:Disconnect() → ()
