src/pmc/hash.pmc - Hash PMC

DESCRIPTION

These are the vtable functions for the Hash PMC.

Functions

static PMC *get_integer_pmc(PARROT_INTERP, INTVAL base_type )
Lookup the PMC type which is used for storing native integers.RT #46641: PMCs extending Hash should probably register themselves.
static PMC *get_number_pmc(PARROT_INTERP, INTVAL base_type )
Lookup the PMC type which is used for floating point numbers.RT #46641: PMCs extending Hash should probably register themselves.
static PMC *get_string_pmc(PARROT_INTERP, INTVAL base_type )
Lookup the PMC type which is used for storing strings.RT #46641: PMCs extending Hash should probably register themselves.
static STRING *make_hash_key(PARROT_INTERP, PMC *key)
Returns a Parrot string for *key.
void init()

INTVAL is_equal(PMC *value)
The == operation.Check if two hashes hold the same keys and values.
INTVAL exists_keyed_str(STRING *key)
INTVAL exists_keyed(PMC *key)
Returns whether a key *key exists in the hash.
INTVAL defined_keyed_str(STRING *key)
INTVAL defined_keyed(PMC *key)
Returns whether the value for *key is defined.
void delete_keyed_str(STRING *key)
void delete_keyed(PMC *key)
