Interface ProgramModule

All Superinterfaces:
Group
public interface ProgramModule extends Group
A ProgramModule is a group of ProgramFragments and/or other ProgramModules together with some related information such as a name, comment, and alias. Users create modules to overlay the program with a hierarchical structure. A child of a module is a fragment or module which it directly contains. A parent of a module is a module which has this module as a child. A module may be contained in more than one module. A Program always has at least one module, the root module. The root module cannot be removed and is the ancestor for all other modules and fragments in the program.
