Conflux

Conflux is a lightweight, type-safe, generic application-wide context for Java, providing strongly-typed key/value storage, listener support, and thread-safe sharing of data. It helps coordinate shared state across otherwise decoupled classes.

Features

Strongly typed keys - no unsafe casting
Type-consistent storage - values always match their declared key type
Change notifications - listeners (held via weak references) react to updates without memory leaks
Thread-safe - built on concurrent data structures
Simple singleton API - provided via an enum instance
Ephemeral named contexts - create multiple independent, short-lived contexts for modular scoping (per user, per request, per transaction)

Quick Link

Example

Key<Integer> counterKey = Key.of("counter", Integer.class);
Ctx.INSTANCE.put(counterKey, 42);

// Working with multiple named contexts
CtxInterface orderCtx = Ctx.INSTANCE.getContext("order");
Key<String> orderIdKey = Key.of("orderId", String.class);
orderCtx.put(orderIdKey, "ORD123");

Enjoy consistent, simple context management!
