An in-memory store for instances.

Typedefs

typedef struct _DLiteStore DLiteStore#: Store type.

Functions

DLiteStore *dlite_store_create()#: Returns a new store.

void dlite_store_free(DLiteStore *store)#: Frees a store.

DLiteStore *dlite_store_load(DLiteStorage *s)#: Returns a new store populated with all instances in storage s.

int dlite_store_save(DLiteStorage *s, DLiteStore *store)#: Saves store to storage. Returns non-zero on error.

int dlite_store_add(DLiteStore *store, DLiteInstance *inst)#: Adds instance to store. The ownership is retained with the caller. Returns non-zero on error.

int dlite_store_add_new(DLiteStore *store, DLiteInstance *inst)#: Adds instance to store, giving away the ownership to the store. Hence, the instance will be free’ed when the store is free’ed. Returns non-zero on error.

DLiteInstance *dlite_store_pop(DLiteStore *store, const char *id)#: Removes instance with given id from store and return it. Returns NULL on error.

DLiteInstance *dlite_store_pop_all(DLiteStore *store, const char *id)#: Like dlite_store_pop(), but removes all occurences of the instance in store. Returns NULL on error.

int dlite_store_remove(DLiteStore *store, const char *id)#: Removes instance with given id from store. Returns non-zero on error.

DLiteInstance *dlite_store_get(const DLiteStore *store, const char *id)#: Returns a borrowed pointer to instance, or NULL if id is not in the store.

DLiteStoreIter dlite_store_iter(const DLiteStore *store)#: Returns an initiated iterator for use with dlite_store_next().

const char *dlite_store_next(const DLiteStore *store, DLiteStoreIter *iter)#

Returns the next uuid in store using iterator iter returned by dlite_store_iter(). Returns NULL when there are no more uuid’s.

Example:

  const char *uuid;
  DLiteStore *store = dlite_store_load(storage);
  DLiteStoreIter iter = dlite_store_iter(store);

  while ((uuid = dlite_store_next(store, &iter))) {
     printf("uuid=%s\n", uuid);
  }

struct DLiteStoreIter#

#include <dlite-store.h>

Iteraror type returned by dlite_store_iter().
