handling into the SqlTypeDescriptor contract.
Essentially this is responsible for mapping to/from the intermediate database type representation. Continuing the
AttributeConverter<Integer,String>
example from
SimpleValue.buildAttributeConverterTypeAdapter()
, the "intermediate database type
representation" would be the String representation. So on binding, we convert the incoming Integer to String;
on extraction we extract the value as String and convert to Integer.Constructor and Description |
