A "basetype" means a particular usage of a data type for inheritance
|
|
|
|
|
in another type. Each such basetype usage has its own "binfo"
|
|
|
|
|
object to describe it. The binfo object is a TREE_VEC node.
|
|
|
|
|
|
|
|
|
|
Inheritance is represented by the binfo nodes allocated for a
|
|
|
|
|
given type. For example, given types C and D, such that D is
|
|
|
|
|
inherited by C, 3 binfo nodes will be allocated: one for describing
|
|
|
|
|
the binfo properties of C, similarly one for D, and one for
|
|
|
|
|
describing the binfo properties of D as a base type for C.
|
|
|
|
|
Thus, given a pointer to class C, one can get a pointer to the binfo
|
|
|
|
|
of D acting as a basetype for C by looking at C's binfo's basetypes. */
