/*
* The spec field of a class object encodes the number of the fixed part
* and the type of the indexed part. The fixed part is the number of
* named instance variables. If the spec of a class is indexed, the object
* of the class can be i nstantiated with the size of the indexed part.
*
* For example, on a platform where sizeof(stix_oow_t) is 4,
* the layout of the spec field of a class as an OOP value looks like this:
*
* 31 10 9 8 7 6 5 4 3 2 1 0
* |number of named instance variables|indexed-type|indexability|oop-tag|
*
* the number of named instance variables is stored in high 23 bits.
* the indexed type takes up bit 3 to bit 8 (assuming STIX_OBJ_TYPE_BITS is 6.
* STIX_OBJ_TYPE_XXX enumerators are used to represent actual values).
* and the indexability is stored in bit 2.
*
* The maximum number of named(fixed) instance variables for a class is:
* 2 ^ ((BITS-IN-OOW - STIX_OOP_TAG_BITS) - STIX_OBJ_TYPE_BITS - 1) - 1
*
* STIX_OOP_TAG_BITS are decremented from the number of bits in OOW because
* the spec field is always encoded as a small integer.
*
* The number of named instance variables can be greater than 0 if the
* class spec is not indexed or if it's a pointer indexed class
* (indexed_type == STIX_OBJ_TYPE_OOP)
*
* indexed_type is one of the #stix_obj_type_t enumerators.
