NAME

src/pmc/namespace.pmc - NameSpace PMC

DESCRIPTION

These are the vtable functions for the namespace PMC.

Functions

void init()
Initialize a NameSpace PMC.
void mark()
Marks the namespace as live.
void destroy()
Frees the namespace info struct.
PMC *get_class()
Returns the class or role PMC that is associated with this namespace.
void set_pmc_keyed_str(STRING *key, PMC *value)
Sets *value as the namespace item for *key. This is part of the raw interface. If the PMC value is exactly a NameSpace, SELF will be set as the parent of that namespace and the name key of value is stored too.
void set_pmc_keyed(PMC *key, PMC *value)
If key is a simple key, it works like above. If key is an array of strings or a chained key, add all components to the namespace.
PMC *get_pmc_keyed(PMC *key)
Return the given namespace or PMCNULL. key is either an array of strings, or a possibly nested key.
PMC *get_pmc_keyed_str(STRING *key)
Return the given namespace item or PMCNULL. If the named item is either a NameSpace or a var, the NameSpace is returned.
PMC *get_pmc_keyed_int(INTVAL key)
Return a Sub representing an overridden vtable entry or PMCNULL. This is not really a public API.
void *get_pointer_keyed_str(STRING *key)
void *get_pointer_keyed(PMC *key)
Return the given namespace item or PMCNULL. If the named item is either a NameSpace or a var, the var is returned.TOTAL KLUDGE. ON THE CHOPPING BLOCK.
STRING *get_string()
Return the name of this namespace part.

Methods

METHOD make_namespace(PMC* key)
Create and retrieve the namespace given by key. If the namespace already exists, only retrieve it.
METHOD add_namespace(STRING *name, PMC *namespace)
Stores the given namespace under this namespace, with the given name. Throws an invalid type exception if namespace is not a NameSpace PMC or subclass.
METHOD add_sub(STRING *name, PMC *sub)
Stores the given sub under this namespace, with the given name. Throws an invalid type exception if sub is not a Sub PMC or subclass.
METHOD add_var(STRING *name, PMC *var)
Stores the given variable under this namespace, with the given name.
METHOD get_name()
Returns the name of the namespace as an array of strings.
  $P2 = $P3.'get_name'()
  $S0 = join '::', $P2            # '::Foo::Bar'
METHOD find_namespace(STRING *name)
Return the namespace with the given name.
METHOD find_sub(STRING *name)
Return the Sub PMC with the given name.
METHOD find_var(STRING *name)
Return the PMC with the given name.
METHOD del_namespace(STRING *name)
Deletes the contained NameSpace PMC with the given name. Throws an invalid type exception if the item to delete is not a NameSpace PMC or subclass, and does not delete the PMC.
METHOD del_sub(STRING *name)
Deletes the contained Sub PMC with the given name. Throws an invalid type exception if the item to delete is not a Sub PMC or subclass, and does not delete the PMC.
METHOD del_var(STRING *name)
Deletes the contained variable-like PMC with the given name.
METHOD get_sym(STRING *name)
Return the symbol (var or sub) with the given name. This can be used to retrieve symbols, if a NameSpace with the same name exists.
METHOD export_to(PMC *dest, PMC *what)
Export items from this NameSpace into the dest NameSpace. The items to export are named in what, which may be an array of strings, a hash, or null. If what is an array of strings, interpretation of items in an array follows the conventions of the source (exporting) namespace. If what is a hash, the keys correspond to the names in the source namespace, and the values correspond to the names in the destination namespace. if a hash value is null or an empty string, the name in the hash key is used. A null what requests the 'default' set of items. Any other type passed in what throws an exception.NOTE: exporting 'default' set of items is not yet implemented.
METHOD get_parent()
Return the parent NameSpace or PMCNULL, if none.
METHOD get_class()
Returns the class or role PMC that is associated with this namespace.
METHOD set_class(PMC *class_or_role)
Sets the class or role PMC that is associated with this namespace.
METHOD get_associated_methods()
Gets the Hash of methods associated with this namespace and removes it from the namespace.
METHOD get_associated_vtable_methods()
Gets the Hash of vtable methods associated with this namespace and removes it from the namespace.
