NAME
src/pmc/default.pmc - Abstract root class
DESCRIPTION
These are the vtable functions for the default PMC class.
All methods which are not defined here get a default implementation generated from src/vtable.tbl by tools/build/pmc2c.pl.
Functions
static STRING * caller(PARROT_INTERP, PMC *pmc)
Returns a C string for the name of static void cant_do_method(PARROT_INTERP, PMC *pmc, int index)
Throws an exception "$methname() not implemented in class '$class'",
used by all unimplemented messages.
static void cant_do_write_method(PARROT_INTERP, PMC *pmc, int index)
Throws an exception "$methname() on read-only instance of '$class'",
used by all updating messages on read-only instances.
static INTVAL check_set_std_props(PARROT_INTERP, PMC *pmc, const STRING *key, PMC *value)
Called from static void propagate_std_props(PARROT_INTERP, PMC *self, PMC *prop_hash)
Set pending standard properties in static INTVAL has_pending_std_props(const PMC *self)
Returns true if propagate_std_props() would create a non-empty prophash.
static PMC* check_get_std_props(PARROT_INTERP, const PMC *self, const STRING *key)
Checks if we can infer the value of static PMC* make_prop_hash(PARROT_INTERP, PMC *self)
Create a property hash for
*pmc.

If it returns true,
the property setting will be reflected in a future call to propagate_std_props()
