Searching for a key that is not present in the hash-map, inserts the key into the map

[Sayan Goswami]

Hi,

I have a sparsehashmap with uint64_t key type and a pointer to a structure as the value type. 

If I have value_t * value = map[key] and the key is not present in the map, a <key, NULL> pair seems to be inserted automatically into it which messes up the size().

Is this behaviour expected?

Thanks,

Sayan

Yes, it is expected. You may want to use find() or count().
