Watchables
Library defines watchable value abstraction, in form of three polymorphic methods, where each one can be extended per type.
watchers
watchables/watchers module provides method that has no default implementation and supposed to be defined per type that wishes to implement this watchable abstraction:
var watchers = { /* ... */ }watchers
watch
watchables/watch module provides
polymorphic method that comes with a default implementation. Given that it's
called with a value that implements watchers
method and a observer function,
it will register given observer for the value unless it's already being
registered. Method can be defined for a specific type to better reflect
it's needs.
var watch =
Method can also be extended with a type specific implementation.
var watch = watch
unwatch
watchables/unwatch module provides
polymorphic method that comes with a default implementation. Given that it's
called with a value that implements watchers
method and a observer function,
it will unregister given observer for the value, if it's registered.
var unwatch =
Method can be extended with a type specific implementation.
var unwatch = unwatch
