QuickHashStringIntHash::delete — This method deletes an entry from the hash
説明
This method deletes an entry from the hash, and returns whether the entry was deleted or not. Associated memory structures will not be freed immediately, but rather when the hash itself is freed.
Elements can not be deleted when the hash is used in an iterator. The
method will not throw an exception, but simply return false
like would
happen with any other deletion failure.
パラメータ
key
-
The key of the entry to delete.
