NAME

src/pmc/packfile.pmc - Packfile PMC

DESCRIPTION

This class implements a Packfile object, as specified in PDD13. This object is the top level parser and serializer for *.pbc files.

Methods

static void copy_packfile_header(PARROT_INTERP, PMC *self, PackFile *pf)

Copy attributes from PackFile* to Packfile PMC.

void init()

Initialize the structure. (Create a blank PackFile object.)

VTABLE void init_pmc(view)

Create a new PackFile from an existing PackFileView.

void mark()

Marks the Packfile as alive.

STRING *get_string()

Return raw serialized PBC file data.

void set_string_native(STRING *str)

Parse raw serialized PBC file data into the Packfile data structure.

void set_pointer(void *ptr)

Set a raw PackFile* pointer to this Packfile PMC

INTVAL get_integer_keyed_str(STRING *key)

Fetch an integer keyed value from the packfile object. Valid keys are:

wordsize

byteorder

fptype

version_major

version_minor

version_patch

bytecode_major

bytecode_minor

uuid_type

STRING *get_string_keyed_str(STRING *key)

Fetch a string keyed value from the packfile object. Valid keys are:

uuid

INTVAL get_integer_keyed(PMC *key)

Fetch a keyed integer value from the packfile object. Dispatches to get_integer_keyed_str.

STRING *get_string_keyed(PMC *key)

Fetch a keyed string value from the packfile object. Dispatches to get_string_keyed_str.

void set_integer_keyed_str(STRING *key, INTVAL value)

Set an integer keyed value to the specified value. Valid keys are:

version_major

version_minor

version_patch

uuid_type

void set_integer_keyed(PMC *key, INTVALval)

Set a keyed integer value in the packfile object. Dispatches to set_integer_keyed_str.

get_string_keyed_str (v-table)

Used to get data about fields in the header that have a string value. Valid keys are:

uuid

void set_string_keyed(PMC *key, STRING *val)

Set a keyed string value in the packfile object. Dispatches to set_string_keyed_str.

STRING * pack()

Return raw serialized PBC file data. Synonym for get_string.

void unpack(STRING *data)

Parse raw serialized PBC file data into the Packfile data structure. Synonym for set_string.

PMC *get_directory()

Fetch the PackfileDirectory PMC that represents the directory segment at the start of the packfile.

PMC *view()

Get a PackfileView for the current packfile. PackfileView is a read-only wrapper around a static packfile structure. This method creates a fresh copy of the packfile structure and assigns that copy to the new PackfileView PMC.

Auxliary functions

static AttrEnumPackfile getAttrEnum(PARROT_INTERP, const STRING *name)

Gets an enumerated value corresponding to the attribute with that name.
