C++ (Cpp) Obj_Hash_Sum Examples

Example #1

File: TestObj.c Project: pavansondur/lucy

static void
test_Hash_Sum(TestBatch *batch) {
    Obj *testobj = S_new_testobj();
    int64_t address64 = PTR_TO_I64(testobj);
    int32_t address32 = (int32_t)address64;
    TEST_TRUE(batch, (Obj_Hash_Sum(testobj) == address32),
              "Hash_Sum uses memory address");
    DECREF(testobj);
}

Example #2

File: Hash.c Project: hernan604/lucy

Obj*
Hash_Delete_IMP(Hash *self, Obj *key) {
    HashEntry *entry = SI_fetch_entry(self, key, Obj_Hash_Sum(key));
    if (entry) {
        Obj *value = entry->value;
        DECREF(entry->key);
        entry->key       = (Obj*)TOMBSTONE;
        entry->value     = NULL;
        entry->hash_sum  = 0;
        self->size--;
        self->threshold--; // limit number of tombstones
        return value;
    }
    else {
        return NULL;
    }
}

Example #3

File: Hash.c Project: hernan604/lucy

Obj*
Hash_Fetch_IMP(Hash *self, Obj *key) {
    HashEntry *entry = SI_fetch_entry(self, key, Obj_Hash_Sum(key));
    return entry ? entry->value : NULL;
}

Example #4

File: Hash.c Project: hernan604/lucy

void
Hash_Store_IMP(Hash *self, Obj *key, Obj *value) {
    Hash_do_store(self, key, value, Obj_Hash_Sum(key), false);
}
