NAME

src/pmc/object.pmc - Object PMC

DESCRIPTION

Implements an instance of a class.

Functions

static INTVAL get_attrib_index(PARROT_INTERP, PMC *self, STRING *name)

Find the index of an attribute in an object's attribute store and return it. Return -1 if the attribute does not exist.

static INTVAL get_attrib_index_keyed(PARROT_INTERP, PMC *self, PMC *key, STRING *name)

This variation bypasses the cache and finds the index of a particular parent's attribute in an object's attribute store and returns it. Returns -1 if the attribute does not exist.

static PMC * find_cached(PARROT_INTERP, PMC *_class, STRING *name)

Search for a method in a class' method cache, if available. If no cache is available, return PMCNULL.

static void cache_method(PARROT_INTERP, PMC *_class, STRING *name, PMC *method)

Add a method to a class' method cache. If no method cache exists, create one.

static PMC* clone_key_arg(PARROT_INTERP, PMC *key)

Replaces any src registers by their values. Used for *_keyed overrides.

void init()

Raises an exception; you can only instantiate objects from a class.

void init_pmc(PMC *class)

Raises an exception; you can only instantiate objects from a class.

void destroy()

Just to avoid the automatic generation of one.

STRING *name()

Returns the fully qualified name of the object's class.

void mark()

Mark any referenced strings and PMCs.

PMC *get_attr_str(STRING *name)

Gets the value of an attribute for this object. Will find the first attribute of the given name walking up the inheritance tree.

PMC *get_attr_keyed(PMC *key, STRING *name)

Gets the value of an attribute for this object. Will only look for attributes defined in the parent identified by the given key.

void set_attr_str(STRING *name, PMC *value)

Sets the value of an attribute for this object. Will set the first attribute of the given name walking up the inheritance tree.

void set_attr_keyed(PMC *key, STRING *name, PMC *value)

Sets the value of an attribute for this object. Will only set attributes defined in the parent identified by the given key.

PMC *find_method(STRING *name)

Queries this object's class to find the method with the given name.

INTVAL get_integer()

Invoke the PIR-defined vtable override, or call the default get_integer.

PMC *get_class()

Get the class PMC representing the class that this object is an instance of.

PMC *get_namespace()

Get the namespace PMC associated with the class that this object is an instance of.

INTVAL isa_pmc(PMC *lookup)

Returns whether the object's class is or inherits from lookup.

INTVAL isa(STRING *classname)

Returns whether the class is or inherits from *classname.

INTVAL does(STRING *role_name)

Returns whether the object's class does the role with name *role_name.

INTVAL does_pmc(PMC *role)

Returns whether the object's class does *role.

opcode_t *invoke(void *next)

Invokes the object (if this vtable function is overridden).

INTVAL type()

Returns the integer type of the object's class.

PMC * clone()

Creates a clone of the object.

void visit(PMC *info)

This is used by freeze/thaw to visit the contents of the object.*info is the visit info, (see include/parrot/pmc_freeze.h).

void freeze(PMC *info)

void thaw(PMC *info)

Realias magically generated methods so they don't wreak havoc.The info arguments are ignored.

void thawfinish(PMC *info)

Called after the object has been thawed.

void morph(PMC* type)

Changes the PMC to a PMC of a new type
