Interface MetaInfoManager

All Known Implementing Classes:

AbstractMetaInfoManager, Role2MetaInfoManager

public interface MetaInfoManager

MetaInfoManager Interface, use this to specify the Components and how they correspond to easy shorthand names. The MetaInfoManager assumes a one to one relationship of shorthand names to classes. A component can have any number of roles associated with it, so it is more flexible and robust than the {@link RoleManager) alternative.
