- /* -----------------------------------------------------------------------------
- * Type initialization:
- * This problem is tough by the requirement that no dynamic
- * memory is used. Also, since swig_type_info structures store pointers to
- * swig_cast_info structures and swig_cast_info structures store pointers back
- * to swig_type_info structures, we need some lookup code at initialization.
- * The idea is that swig generates all the structures that are needed.
- * The runtime then collects these partially filled structures.
- * The SWIG_InitializeModule function takes these initial arrays out of
- * swig_module, and does all the lookup, filling in the swig_module.types
- * array with the correct data and linking the correct swig_cast_info
- * structures together.
- *
- * The generated swig_type_info structures are assigned statically to an initial
- * array. We just loop through that array, and handle each type individually.
- * First we lookup if this type has been already loaded, and if so, use the
- * loaded structure instead of the generated one. Then we have to fill in the
- * cast linked list. The cast data is initially stored in something like a
- * two-dimensional array. Each row corresponds to a type (there are the same
- * number of rows as there are in the swig_type_initial array). Each entry in
- * a column is one of the swig_cast_info structures for that type.
- * The cast_initial array is actually an array of arrays, because each row has
- * a variable number of columns. So to actually build the cast linked list,
- * we find the array of casts associated with the type, and loop through it
- * adding the casts to the list. The one last trick we need to do is making
- * sure the type pointer in the swig_cast_info struct is correct.
- *
- * First off, we lookup the cast->type name to see if it is already loaded.
- * There are three cases to handle:
- * 1) If the cast->type has already been loaded AND the type we are adding
- * casting info to has not been loaded (it is in this module), THEN we
- * replace the cast->type pointer with the type pointer that has already
- * been loaded.
- * 2) If BOTH types (the one we are adding casting info to, and the
- * cast->type) are loaded, THEN the cast info has already been loaded by
- * the previous module so we just ignore it.
- * 3) Finally, if cast->type has not already been loaded, then we add that
- * swig_cast_info to the linked list (because the cast->type) pointer will
- * be correct.
