Module: Sequel::Plugins::Serialization::ClassMethods

Attributes

deserialization_map	[R]	A hash with column name symbols and callable values, with the value called to deserialize the column.
serialization_map	[R]	A hash with column name symbols and callable values, with the value called to serialize the column.
serialization_module	[RW]	Module to store the serialized column accessor methods, so they can call be overridden and call super to get the serialization behavior

Public Instance methods

inherited(subclass)

Copy the serialization_map and deserialization map into the subclass.

serialize_attributes(format, *columns)

Create instance level reader that deserializes column values on request, and instance level writer that stores new deserialized values.

serialized_columns()

The columns that will be serialized. This is only for backwards compatibility, use serialization_map in new code.
