NAME

SPVM::Document::NativeAPI - SPVM Native API

What is Native API

Native API is C level functions to manipulate data of SPVM in Extension.

If you need more performance or bind C/C++ functions, you can use Extension and Native API.

is_type

int32_t is_type(SPVM_ENV* env, void* object, int32_t basic_type_id, int32_t type_dimension)

Check object is specified type.

Arguments:

1th : env

2th : object (This object must be not NULL)

3th : basic type id

4th : type dimension

Return:

If object is specifed type, return 1, else return 0.

Example:

// Get basic type id
int32_t basic_type_id = env->basic_type_id(env, "Point");
if (basic_type_id < 0) {
  assert(0);
}

// Check if object type is Point
int32_t match = env->is_type(env, object, basic_type_id, 0);

// Check if object type is Point[]
int32_t match = env->is_type(env, object, basic_type_id, 1);

// Check if object type is Point[][]
int32_t match = env->is_type(env, object, basic_type_id, 2);
