|
|
*
|
|
* _size: the number of payload items in an object.
|
|
* it doesn't include the header size.
|
|
*
|
|
* The total number of bytes occupied by an object can be calculated
|
|
* with this fomula:
|
|
* sizeof(hak_obj_t) + ALIGN((size + extra) * unit), sizeof(hak_oop_t))
|
|
*
|
|
* If the type is known to be not HAK_OBJ_TYPE_CHAR, you can assume that
|
|
* 'extra' is 0. So you can simplify the fomula in such a context.
|
|
* sizeof(hak_obj_t) + ALIGN(size * unit), sizeof(hak_oop_t))
|
|
*
|
|
* The ALIGN() macro is used above since allocation adjusts the payload
|
|
* size to a multiple of sizeof(hak_oop_t). it assumes that sizeof(hak_obj_t)
|
|
* is a multiple of sizeof(hak_oop_t). See the HAK_BYTESOF() macro.
|
|
*
|
|
* Due to the header structure, an object can only contain items of
|
|
* homogeneous data types in the payload.
|
|
*
|
|
* It's actually possible to split the size field into 2. For example,
|
|
* the upper half contains the number of oops and the lower half contains
|
|
* the number of bytes/chars. This way, a variable-byte class or a variable-char
|
|
* class can have normal instance variables. On the contrary, the actual byte
|
|
* size calculation and the access to the payload fields become more complex.
|
|
* Therefore, i've dropped the idea.
