                          V value,
                          Metadata metadata)

Description copied from interface: KeyValueFilterConverter

Will both filter the entry and if passed subsequently convert the value to a new value. A returned value of null will symbolize the value not passing the filter, so ensure your conversion will not return null if you want this entry to be returned.

Parameters:

key - The key of the entry to filter

value - The value of the entry to filter and then convert

metadata - The metadata attached to the entry

Returns:

The converted value or null if the filter didn't pass
