Interface ContextProperty<T>

Type Parameters:

T - item type.

All Superinterfaces:

Serializable

All Known Implementing Classes:

ContextProperty.Impl, ContextProperty.Wrapper, LeakagePreventingWrapper

public interface ContextProperty<T>
extends Serializable

Observable property. Provides two flavours of observation:

• null-safe, which yields optionals to the observers
• nullable, which may broadcast nulls

Also provides the mutation capabilities in imperative and functional styles. Imperative is useful when we merely want to swap one value with another, whereas the functional one can be used when e.g. another element needs to be added to a collection.
