Interface SystemReadyMonitor

All Superinterfaces:

SystemReadyMonitorMXBean

All Known Implementing Classes:

KarafSystemReady, SimpleSystemReadyMonitor, TestSystemReadyMonitor

public interface SystemReadyMonitor
extends SystemReadyMonitorMXBean

Service which provides technical system ready-ness status.

This API is intentionally not specific to OSGi and Karaf, but using more general terminology.

In an OSGi context, "fully ready" means that the asynchronous installation of (boot) features has successfully completed installation of all of their bundles, that all of these bundles have successfully started, and all of their blueprint containers have been successfully initialized.

Implementations of this interface are expected to be thread-safe.
