SJF4J: A Structured JSON Facade for Java

Introduction Working with JSON in Java usually means choosing between two approaches: Data binding (POJO) — strong typing, but rigid Tree model (JsonNode / Map) — flexible, but unstructured Most libraries force you to pick one and live with the trade-offs. SJF4J (Simple JSON Facade for Java) takes a different approach: it introduces a unified JSON-semantic layer that supports both structured and dynamic access — without locking you into a single model. What SJF4J Is SJF4J is not a JSON parser. It is a facade layer built on top of existing parsers (e.g., Jackson), providing: Unified node model Structured + dynamic access Schema-aware capabilities JSON-semantic operations The goal is to make JSON handling more consistent, expressive, and extensible. Core Idea: Unified Node Semantics In SJF4J, all JSON values are treated as nodes with consistent behavior. You can operate on them via: Object-oriented APIs (JsonObject, JsonArray) Static utilities (Nodes) Two access styles are supported: toX
