NAME

src/pmc/sarray.pmc - Simple Array or Subroutine Parameter Array

DESCRIPTION

Simple Array or Subroutine Parameter Array PMC. SArray data are kept in an malloced array of HashEntrys:

0 start_idx

First index, for shift.

1 end_idx

Last index, for push.

2...

Data.

SArrays are fixed size, implying that the first operation on it must be setting its size, and that only the most important vtable methods are implemented.

Currently SArrays are used for:

Global data per interpreter

Implementing lists, see src/list.c.

Base class of the Exception PMC, see src/exception.pmc

Functions

static PARROT_INLINE INTVAL ret_int(PARROT_INTERP, const HashEntry *e)

Processes *e, returning the appropriate integer, or raising an exception if necessary.

static PARROT_INLINE FLOATVAL ret_num(PARROT_INTERP, const HashEntry *e)

Processes *e, returning the appropriate floating-point number, or raising an exception if necessary.

static PARROT_INLINE STRING *ret_string(PARROT_INTERP, HashEntry *e)

Processes *e, returning the appropriate Parrot string, or raising an exception if necessary.

static PARROT_INLINE PMC *ret_pmc(PARROT_INTERP, const HashEntry *e)

Processes *e, returning the appropriate PMC, or raising an exception if necessary.

static PARROT_INLINE HashEntry *shift_entry(PARROT_INTERP, PMC *self)

Removes and returns the first element from the array.

static PARROT_INLINE HashEntry *get_entry(PARROT_INTERP, PMC *self, INTVAL key)

Returns the element for index key.

Methods

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.

STRING *shift_string()

Removes the first element from the array and returns its Parrot string value.

PMC *get_pmc_keyed_int(INTVAL key)

Returns the PMC value of the element at index key.

PMC *get_pmc_keyed(PMC *key)

void set_integer_native(INTVAL size)

Resizes the array to size elements.

void set_integer_keyed_int(INTVAL key, INTVAL value)

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

void push_integer(INTVAL value)

Adds an element with integer value value to the end of the array.

void set_number_keyed_int(INTVAL key, FLOATVAL value)

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

void push_float(FLOATVAL value)
