54 /** \brief A macro to provide a uniform interface for storing lists of
55  objects.
56 
57  This macro is designed to be used in the body of an object to add
58  a set of methods for manipulating a list of contained objects. It adds
59  methods
60  - get_foo
61  - set_foo
62  - set_foos
63  - foos_begin, foos_end
64  - remove_foo
65  - remove_foos
66  etc. where foo is the lcname provided.
67 
68  \param[in] protection The level of protection for the container
69  (public, private).
70  \param[in] Ucname The name of the type of container in uppercase.
71  \param[in] lcname The name of the type of container in lower case.
72  \param[in] Data The type of the data to store.
73  \param[in] PluralData The plural of the data name. This should be a
74  container type.
75 
76  An accompanying IMP_LIST_IMPL must go in a \c .cpp file.
77 
78  \note This macro should be given an appropriate name and wrapped in a
79  doxygen comment block such as by starting with a C++ comment like
80  \verbatim
81  @name short description
82  longer description
83  @{
