NAME
src/pmc/pmcproxy.pmc - proxy class object for a PMC enabling introspection
DESCRIPTION
This class is used to describe a PMC. It can sit in an inheritance hierarchy of a PDD15 class as well as allowing introspection of the PMC.
PMCProxy is not derived from any other PMC.
Structure
This class stores its state in the Parrot_Class structure, using the following fields.
id
The type number of the PMC that is being described.
name
The name of the PMC -- a STRING.
namespace
The namespace the PMC is associated with,
if any.
parents
An array of immediate parent classes.
An empty ResizablePMCArray PMC is allocated during initialization.
all_parents
A cached array of ourself and all parent classes,
in MRO order.
A ResizablePMCArray PMC is allocated during initialization,
and is populated with the current class.
NOTE: No doubt we will need other things later; this is a start.
Functions
