Env

Overview

Module

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

Read-only view of process environment variables. get(String) returns a single value, list() returns the full map as a JSON document — handy for debug endpoints or feature-flag inspection from an admin UI.

Note that for configuration knobs that also have a DIRIGIBLE_* configuration key (Configuration.get(...) or Configurations) you should usually read the configuration value, not the raw env var — the configuration layer also honours DIRIGIBLE_* property files and runtime overrides.

Key Features

• Read-only: There is no set — env vars are immutable from the JVM's perspective.
• JSON dump: list() returns the full environment as JSON, ready to feed to a UI or log.
• Static API: No instance, no state — just call the methods.

Example Usage

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

// Read a single variable
String home = Env.get("HOME");

// Get the entire environment as a JSON document
String envJson = Env.list();
