Documentation

class (Message (Mesg prt us), Show (Mesg prt us)) => Participant prt us where Source #

This typeclass defines the behaviour of a participant in the message system

Minimal complete definition

partSubscribers, partSubscribe, partUnSubscribe

Associated Types

type Mesg prt us :: * Source #

Message datatype

Methods

partSubscribers Source #

Arguments

:: prt	the `Participant'`s subscriber storage
-> Affection us [Mesg prt us -> Affection us ()]	List of Subscriber functions

Function to get the list of subscribers from the participant

partSubscribe Source #

Arguments

:: prt	The `Participant'`s subscriber storage
-> (Mesg prt us -> Affection us ())	What to do in case of a `Message` (Subscriber function)
-> Affection us UUID	`UUID` of the registered subscriber Function

Subscribe to the Participant's events

partUnSubscribe Source #

Arguments

:: prt	The `Participant'`s subscriber storage to unsubscribe from
-> UUID	The subscriber function's `UUID`
-> Affection us ()

Unsubscribe a Subscriber function from Participant

partEmit Source #

Arguments

:: prt	The `Participant'`s subscriber storage
-> Mesg prt us	The `Message` to emit
-> Affection us ()

Get the Participant to emit a Message on all of its subscribers

genUUID :: Affection us UUID Source #

Helper function to generate new UUIDs

data UUID #

The UUID type. A Random instance is provided which produces version 4 UUIDs as specified in RFC 4122. The Storable and Binary instances are compatible with RFC 4122, storing the fields in network order as 16 bytes.
