NAME

dynclasses/gdbmhash.pmc - GDBM PMC

DESCRIPTION

This is an interface to the GNU dbm library.

On inserted and fetch, keys are converted to STRINGs.

PMC insert values are convered to STRINGs. TODO: Integer insert values are converted to STRINGs. TODO: Number insert values are converted to STRINGs.

get_integer_keyed() and get_number_keyed() make propably no sense, as integers usually can't be converted.

When a PMC is requested, a String PMC is returned.

TODO: return None PMC for nonexisting keys.

static STRING *make_hash_key(Interp *interpreter, PMC *key): Returns a Parrot string for *key.
void class_init(): Class initialization. Allocates the memory for the hash.
VOID set_string_native(STRING *value): Open a or create a new dbm file.
INTVAL get_integer(): Returns the number of pairs in the hash. A uninitialized GDBMHash returns 0.
INTVAL get_bool(): Returns true if the hash size is not zero.
void set_string_keyed(PMC *key, STRING *value)
STRING *get_string_keyed(PMC *key): Returns the string value for the element at *key.
void set_pmc_keyed(PMC *key, PMC *value): Convert value to a string and set the string for the key.
PMC *get_pmc_keyed(PMC *key): Returns the PMC value for the element at *key.
void set_integer_keyed(PMC *key, INTVAL value): Convert value to a string and set the string for the key.
void set_number_keyed(PMC *key, FLOATVAL value): Convert value to a string and set the string for the key.
INTVAL exists_keyed(PMC *key): Returns whether a key *key exists in the hash.
void delete_keyed(PMC *key): Deletes the element associated with *key.
