Ada Programming/Attributes/'Finalization Size

Description

The prefix of attribute Finalization_Size must be an object or a non-class-wide type. This attribute returns the size of any hidden data reserved by the compiler to handle finalization-related actions. The type of the attribute is universal_integer.

Finalization_Size yields a value of zero for a type with no controlled parts, an object whose type has no controlled parts, or an object of a class-wide type whose tag denotes a type with no controlled parts.

Note that only heap-allocated objects contain finalization data.
