Detailed Description

Flagging conditions.

for specifying conditional objets that are only active when this condition is verified. Works in conbination with UFlagdef. Example:

const UFlag showStores, showMuseums;

  UBox& stores = ...;  // whatever
  UBox& museums = ...; // whatever
  UBox& scene = ubox( showStores/stores + showMuseums/museums );

  // the stores appear in this box (the museums are ignored)
  UBox& scene_with_stores  = ubox( uflagdef(showStores) + scene);

  // the museums appear in this box (the stores are ignored)
  UBox& scene_with_museums = ubox( uflagdef(showMuseums) + scene);

!Warning: UFlag objects must not be deleted! See also: UFlagdef, UPropdef.
