Interface Loader

public interface Loader

Loader is the persistent manager of all workflow components that subclass Element. When a new component is created, this class will be used to create its persistent representation. It's subclass is responsible for specialization on a certain persistent resource. The configruation of such persistent resource is passed through WorkflowContext. We do not dicate the format as how this information is formatted.
