Examples of org.osgi.framework.Bundle.loadClass()

org.osgi.framework.Bundle.loadClass()
Loads the specified class using this bundle's class loader.
If this bundle is a fragment bundle then this method must throw a ClassNotFoundException.
If this bundle's state is INSTALLED, this method must attempt to resolve this bundle before attempting to load the class.
If this bundle cannot be resolved, a Framework event of type {@link FrameworkEvent#ERROR} is fired containing aBundleException with details of the reason this bundle could not be resolved. This method must then throw a ClassNotFoundException.
If this bundle's state is UNINSTALLED, then an IllegalStateException is thrown. @param name The name of the class to load. @return The Class object for the requested class. @throws ClassNotFoundException If no such class can be found orif this bundle is a fragment bundle or if the caller does not have the appropriate AdminPermission[this,CLASS], and the Java Runtime Environment supports permissions. @throws IllegalStateException If this bundle has beenuninstalled. @since 1.3
