rescala

default

object default extends RescalaInterface with Unmanaged

REScala has two main abstractions. rescala.default.Event and rescala.default.Signal commonly referred to as reactives. Use rescala.default.Var to create signal sources and rescala.default.Evt to create event sources.

Events and signals can be created from other reactives by using combinators, signals additionally can be created using rescala.default.Signal expressions.

    Events only propagate a value when they are changing, when the system is at rest, events have no values.

    Events only propagate a value when they are changing, when the system is at rest, events have no values.

    Note: We hide implicit parameters of the API in the documentation. They are used to ensure correct creation, and you normally do not have to worry about them, except if you accidentally call the implicit parameter list, in which cas you may get cryptic errors. This is a scala limitation. We also hide the internal state parameter of passed and returned events.
