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.

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)
