class DWARFUnitHeader

Declaration

class DWARFUnitHeader { /* full declaration omitted */ };

Description

Base class describing the header of any kind of "unit." Some information is specific to certain unit types. We separate this class out so we can parse the header before deciding what specific kind of unit to construct.
