Interface ClassLoadingStrategy

All Known Implementing Classes:

OSGiClassLoadingStrategy, SimpleClassLoadingStrategy

public interface ClassLoadingStrategy

Strategy to be able to switch class loading mechanisms, depending on the needs for a runtime environment (especially for actors and other model entities),

In a "plain" Java SE runtime, a default implementation would use simple Class.forName() (for Java classes) or local file-lookup (for actor-oriented classes) or similar.

In an OSGi-based runtime, more advanced options can be implemented to allow dynamic actor class updates, version management etc.
