This method updates an entry with a new value, and returns whether the entry was update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashIntStringHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

Parámetros

key

The key of the entry to update.

value

The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

Valores devueltos

true when the entry was found and updated, and false if the entry was not part of the hash already.
