NAME

src/pmc/ref.pmc - Reference to a PMC

DESCRIPTION

The vtable functions for the Ref base class.

All methods not present below get a default body autogenerated inside Parrot::Pmc2c.

void init(): Sets the referenced PMC to PMCNULL.
void init_pmc(PMC *initializer): Sets the referenced PMC to initializer.
void set_pmc(PMC *other): Sets the referenced PMC to *other.
PMC *get_pmc(): Get the referenced PMC.
INTVAL type(): Returns the PMC's type.
void mark(): Marks the referenced PMC as live.

These two methods must be implemented because they are not delegated.

STRING *name(): Returns the name of the PMC, not the name of the referenced PMC.
void morph(INTVAL type): Changes the PMC to a PMC of a new type.
