NAME

classes/fixedstringarray.pmc - fixed size array for strings only

DESCRIPTION

This class, FixedStringArray, implements an array of fixed size, which stores Parrot strings.

Functions

Methods

void init()

Initializes the array.

void morph(INTVAL type)

Const classes must have a morph().

void destroy()

Destroys the array.

PMC *clone()

Creates and returns a copy of the array.

void mark()

Marks the array as live.

INTVAL get_bool()

Returns 1 if the array has any elements; otherwise, returns 0. Since this is a fixed size array, get_bool will always return true once the array has been initialized and had its size set by set_integer_native.

INTVAL elements()

Returns the number of elements in the array.

INTVAL get_integer()

Returns the number of elements in the array.

INTVAL get_integer_keyed_int(INTVAL key)

Returns the integer value of the element at index key.

INTVAL get_integer_keyed(PMC *key)

Returns the integer value of the element at index *key.

FLOATVAL get_number_keyed_int(INTVAL key)

Returns the floating-point value of the element at index key.

FLOATVAL get_number_keyed (PMC *key)

Returns the floating-point value of the element at index *key.

STRING *get_string_keyed_int(INTVAL key)

Returns the Parrot string value of the element at index key.

STRING *get_string_keyed(PMC *key)

Returns the Parrot string value of the element at index *key.

PMC *get_pmc_keyed_int(INTVAL key)

Returns the PMC value of the element at index key.

PMC *get_pmc_keyed(PMC *key)

Returns the PMC value of the element at index *key.

void set_integer_native(INTVAL size)

Sets the size of the array to size elements. Once the array has been given an initial size, attempts to resize it will cause an exception to be thrown.

void set_integer_keyed_int(INTVAL key, INTVAL value)

Sets the integer value of the element at index key to value.

void set_integer_keyed(PMC *key, INTVAL value)

Sets the integer value of the element at index key to value.

void set_number_keyed_int(INTVAL key, FLOATVAL value)

Sets the floating-point value of the element at index key to value.

void set_number_keyed(PMC *key, FLOATVAL value)

Sets the floating-point value of the element at index key to value.

void set_string_keyed_int(INTVAL key, STRING *value)

Sets the Parrot string value of the element at index key to value.

void set_string_keyed(PMC *key, STRING *value)

Sets the string value of the element at index key to value.

void set_pmc_keyed_int(INTVAL key, PMC *src)

Sets the PMC value of the element at index key to *src.

void set_pmc_keyed(PMC *key, PMC *value)

Sets the string value of the element at index key to value.

Freeze/thaw Interface

void freeze(visit_info *info)

Used to archive the string.

void thaw(visit_info *info)

Used to unarchive the string.
