Class ReactorContext

java.lang.Object

dmx.fun.reactor.ReactorContext

@NullMarked
public final class ReactorContext
extends Object

Bridges Reactor's ContextView with dmx-fun's Option, so reading a key that may be absent yields an Option instead of throwing.

Reactor's ContextView.get(Object) throws when a key is missing; this helper models the absence explicitly as Option.none(). It introduces no hidden global state — the ContextView is always passed in by the caller (typically obtained from Mono.deferContextual).

ContextView was introduced in Reactor 3.4; these helpers therefore require Reactor 3.4 or later, even though the ReactorFun conversions work on earlier 3.x releases.
