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 vtable.tbl by tools/build/pmc2c.pl.

Functions

static const char *caller(Interp *interpreter, PMC *pmc): Returns a C string for the name of *pmc.
static void cant_do_method(Interp *interpreter, PMC *pmc, const char *methname): Throws an exception "$methname() not implemented in class '$class'", used by all unimplemented messages.
static void check_set_std_props(Interp *interpreter, PMC *pmc, STRING *key, PMC *value): Called from setprop().
static INTVAL does_isa(Interp *interpreter, STRING *method, STRING *what): Compares *method and *what.

Methods

void init(): Does nothing.
void init_pmc(PMC *initializer): With a null initializer, calls init(), else throws an exception.
PMC *instantiate(PMC *sig): Default fallback. Creates a new PMC of the type of the class SELF and calls init().
void mark(): Panics with a "no custom mark routine defined" error message.
PMC *getprop(STRING *key): Returns the property for *key. If no property is defined then the NULL PMC is returned.
void setprop(STRING *key, PMC *value): Sets the property for *key to *value.
void delprop(STRING *key): Deletes the property for *key.
PMC *getprops(): Returns the PMC's properties or the NULL PMC if no properties exist.
INTVAL type(): Returns the PMC's type.
INTVAL type_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling type_keyed() with it.
STRING *name(): Returns the name of the PMC.
PMC *namespace: Return the namespace for this PMC.
PMC *find_method(STRING *method_name): Looks up the method for *method_name and returns it. If no method is found then NULL is returned.
void add_method(STRING *method_name, PMC *sub): Store the method as a global in the namespace of this class.
INTVAL get_integer_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling get_integer_keyed() with it.
FLOATVAL get_number_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling get_number_keyed() with it.
STRING *get_string_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling get_string_keyed() with it.
INTVAL get_bool_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling get_bool_keyed() with it.
INTVAL elements_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling elements_keyed() with it.
PMC *get_pmc_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling get_pmc_keyed() with it.
INTVAL is_same(PMC *value): Returns whether the PMC is numerically equal to value.
void assign_pmc (PMC *value)
void assign_string_native (PMC *value): Defaults fall back to set_pmc and set_string_native.
void set_integer_keyed_int (INTVAL key, INTVAL value): Converts key to a PMC key and calls set_integer_keyed() with it and value.
void set_number_keyed_int (INTVAL key, FLOATVAL value): Converts key to a PMC key and calls set_number_keyed() with it and value.
void set_string_keyed_int(INTVAL key, STRING *string): Converts key to a PMC key and calls set_string_keyed() with it and value.
void set_bool_keyed_int(INTVAL key, INTVAL value): Converts key to a PMC key and calls set_bool_keyed() with it and value.
void set_pmc_keyed_int(INTVAL key, PMC *value): Converts key to a PMC key and calls set_pmc_keyed() with it and value.
INTVAL is_equal(PMC *value): Returns whether the PMC is equal to *value.
INTVAL is_equal_num(PMC *value): Returns whether the PMC is numerically equal to *value.
INTVAL is_equal_str(PMC *value): Returns whether the PMC is numerically equal to *value.
INTVAL exists_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling exists_keyed() with it.
INTVAL defined(): Returns true.
INTVAL defined_keyed_int(INTVAL key): Converts key to a PMC key and returns the result of calling defined_keyed() with it.
void delete_keyed_int(INTVAL key): Converts key to a PMC key and calls delete_keyed() with it.
PMC *nextkey_keyed_int(INTVAL key, INTVAL w): Converts key to a PMC key and returns the result of calling nextkey_keyed() with it.
INTVAL can(STRING *method): Returns whether the PMC "can" perform *method.
INTVAL does(STRING *interface): Returns whether the PMC "does" perform *interface.
INTVAL isa(STRING *class): Returns whether the PMC "isa" *class.
PMC *subclass(PMC *name): Creates a subclass, optionally with a given name.
PMC *get_class(): Returns SELF. A PMC is it's own class.
PMC *get_attr_str(STRING *attr): Look for NCI methods and properties.
void add_parent(PMC *parent): Add class parent to the list of our parents.
void visit(visit_info *info): Used by DOD to mark the PMC.
void freeze(visit_info *info): Does nothing.
void thaw(visit_info *info): Initializes the PMC during unarchiving.
void thawfinish(visit_info *info): Does nothing.
