serialName

Serial name of the descriptor that identifies a pair of the associated serializer and target class.

For generated and default serializers, the serial name should be equal to the corresponding class's fully qualified name or, if overridden, SerialName. Custom serializers should provide a unique serial name that identifies both the serializable class and the serializer itself, ignoring type arguments, if they are present, for example: my.package.LongAsTrimmedString
