Context

Overview

Module

• package: org.eclipse.dirigible.sdk.core
• source: core/Context.java

Per-request scratch storage bound to the calling thread. Useful for passing values from a filter or interceptor down to a controller method without threading the data through every method signature — for example user-derived language preferences, correlation ids, request-scoped feature flags.

Values are not persisted across requests. For longer-lived global state use Globals; for the actual HTTP session-scoped storage use org.eclipse.dirigible.sdk.http.Session.

Key Features

• Thread-bound: Values are visible only to the thread that wrote them.
• Request-scoped: Cleared between requests — no leak across calls.
• Untyped values: Stores arbitrary Objects, so the caller is responsible for cast safety.

Example Usage

import org.eclipse.dirigible.sdk.core.Context;

// In a request filter / interceptor:
Context.set("correlationId", request.getHeader("X-Correlation-Id"));
Context.set("locale", resolveLocale(request));

// Later, in a controller or service:
String correlationId = (String) Context.get("correlationId");
