src/pmc/resizablepmcarray.pmc - resizable array for PMCs only


This class, ResizablePMCArray, implements an resizable array, which stores PMCs. It puts things into Integer, Float, or String PMCs as appropriate.

Functions ^

void set_integer_native(INTVAL size)

Resizes the array to size elements.

FLOATVAL shift_float()

INTVAL shift_integer()

PMC *shift_pmc()

STRING *shift_string()

Removes and returns an item from the start of the array.

PMC *get_pmc_keyed_int(INTVAL key)

Returns the PMC value of the element at index key.

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 *src)

If key is a slice, do a splice as set that item.

INTVAL exists_keyed_int(INTVAL key)

INTVAL exists_keyed_int(PMC *key)

Returns TRUE is the element at key exists; otherwise returns false.

INTVAL defined_keyed_int(INTVAL key)

Returns TRUE is the element at key is defined; otherwise returns false.

void push_float(FLOATVAL value)

void push_integer(INTVAL value)

void push_pmc(PMC *value)

void push_string(STRING *value)

Extends the array by adding an element of value *value to the end of the array.

INTVAL pop_float()

INTVAL pop_integer()

PMC *pop_pmc()

STRING *pop_string()

void unshift_float(FLOATVAL value)

void unshift_integer(INTVAL value)

void unshift_pmc(PMC *value)

void unshift_string(STRING *value)

Extends the array by adding an element of value *value to the begin of the array.

PMC *clone()

Creates and returns a copy of the array.

INTVAL is_equal(PMC *value)

The == operation. Compares two array to hold equal elements.

METHOD void append(PMC* other)

Append the other array to this array.

STRING *get_repr()

Returns the Parrot string representation ResizablePMCArray.

void splice(PMC *value, INTVAL offset, INTVAL count)

Replaces count elements starting at offset with the elements in value.

Note that the value PMC can be of any of the various array types.

Note that this implementation can be *VERY* inefficient as it manipulates everything via the VTABLE api.
