/************************************************************************* * 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 staticly to an initial * array. We just loop though 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. **/ #ifdef __cplusplus extern "C" { #endif SWIGRUNTIME void SWIG_InitializeModule(void *clientdata) { swig_type_info *type, *ret; swig_cast_info *cast; size_t i; swig_module_info *module_head; static int init_run = 0; clientdata = clientdata; if (init_run) return; init_run = 1; /* Initialize the swig_module */ swig_module.type_initial = swig_type_initial; swig_module.cast_initial = swig_cast_initial; /* Try and load any already created modules */ module_head = SWIG_GetModule(clientdata); if (module_head) { swig_module.next = module_head->next; module_head->next = &swig_module; } else { /* This is the first module loaded */ swig_module.next = &swig_module; SWIG_SetModule(clientdata, &swig_module); } /* Now work on filling in swig_module.types */ for (i = 0; i < swig_module.size; ++i) { type = 0; /* if there is another module already loaded */ if (swig_module.next != &swig_module) { type = SWIG_MangledTypeQueryModule(swig_module.next, &swig_module, swig_module.type_initial[i]->name); } if (type) { /* Overwrite clientdata field */ if (swig_module.type_initial[i]->clientdata) type->clientdata = swig_module.type_initial[i]->clientdata; } else { type = swig_module.type_initial[i]; } /* Insert casting types */ cast = swig_module.cast_initial[i]; while (cast->type) { /* Don't need to add information already in the list */ ret = 0; if (swig_module.next != &swig_module) { ret = SWIG_MangledTypeQueryModule(swig_module.next, &swig_module, cast->type->name); } if (ret && type == swig_module.type_initial[i]) { cast->type = ret; ret = 0; } if (!ret) { if (type->cast) { type->cast->prev = cast; cast->next = type->cast; } type->cast = cast; } cast++; } /* Set entry in modules->types array equal to the type */ swig_module.types[i] = type; } swig_module.types[i] = 0; } /* This function will propagate the clientdata field of type to * any new swig_type_info structures that have been added into the list * of equivalent types.
