88 /** \brief A macro to provide a uniform interface for storing lists of
89  objects.
90 
91  This macro is designed to be used in the body of an object to add
92  a set of methods for manipulating a list of contained objects. It adds
93  methods
94  - get_foo
95  - set_foo
96  - set_foos
97  - erase_foo
98  - foos_begin, foos_end
99  - remove_foo
100  - remove_foos
101  etc. where foo is the lcname provided. In Python, a 'foos' member
102  is also provided, which acts like a regular Python list (the above
103  methods can also be used if desired).
104 
105  \param[in] protection The level of protection for the container
106  (public, private).
107  \param[in] Ucname The name of the type of container in uppercase.
108  \param[in] lcname The name of the type of container in lower case.
109  \param[in] Data The type of the data to store.
110  \param[in] PluralData The plural of the data name. This should be a
111  container type.
112 
113  An accompanying IMP_LIST_IMPL must go in a \c .cpp file.
114 
115  \note This macro should be given an appropriate name and wrapped in a
116  doxygen comment block such as by starting with a C++ comment like
117  \verbatim
118  @name short description
119  longer description
120  @{
121  \endverbatim
