System top-level property

Internal system facade for the JetLeaf framework.

The _System class wraps a SystemProperties implementation and delegates all environment-related method calls to it. It is the central access point for querying runtime information while also exposing system-level streams (out, err) and process management (exit).

This class is not intended to be used directly by end-users. Instead, it acts as the internal bridge between JetLeaf's runtime environment and the underlying system.

Example

final system = _System();
system.setProperties(myProperties);

// Delegated calls
if (system.isDevelopmentMode()) {
  print('Running in dev mode');
}

// System streams
system.out.writeln('Hello stdout');
system.err.writeln('Hello stderr');

// Exit process
system.exit(0);
