+/*!
|
|
+ * \file generators.i
|
|
+ * \author Seth R. Johnson
|
|
+ * \brief Define generator/iterator for any type
|
|
+
|
|
+Example:
|
|
+\code
|
|
+ SETUP_GENERATOR( std::vector<Cell>::const_iterator )
|
|
+ ADD_GENERATOR( Mesh, cells,
|
|
+ std::vector<Cell>::const_iterator, Cell, beginCells, endCells)
|
|
+\endcode
|
|
+would be a method to add a \c cells generator method method to the Python class
|
|
+\c Mesh, when the C++ class \c Mesh has a \c std::vector<Cell> accessed through
|
|
+methods \c beginCells and \c endCells.
|
|
+
|
|
+The macro \c ADD_GENERATOR_P would be if the underlying storage were \c
|
|
+std::vector<Cell*> instead.
|
|
+
|
|
+Alternatively, for containers of regular objects that provide \c begin(), \c end(), and \c const_iterator, you can use the \c ADD_CONTAINER_ITERATOR macro:
|
|
+\code
|
|
+ADD_CONTAINER_ITERATOR( QuadratureSet )
|
|
+\endcode
