public interface TypeConverter<TO_TYPE,DOMAIN_TYPE>

Do type conversion to allow object to be stored using a different type in transfer and domain objects.

Method Summary

Modifier and Type	Method and Description
boolean	canConvert(Type realToType, Type realDomainType) Can this type converter handle conversions between the given transfer and domain object types?
DOMAIN_TYPE	convert(TO_TYPE object, SyntheticField domainField, Object domainObject, String... tags) Convert a transfer object field value to the value for the domain object.
TO_TYPE	reverse(DOMAIN_TYPE object, SyntheticField toField, Object toObject, String... tags) Convert a domain object field value to the value for the transfer object.

Method Detail

canConvert

boolean canConvert(Type realToType,
                   Type realDomainType)

Can this type converter handle conversions between the given transfer and domain object types?

Parameters:

realToType - real class for the type in the transfer object

realDomainType - real class for the type in the domain object

Returns:

true is this type converter can handle the type conversions

convert

DOMAIN_TYPE convert(TO_TYPE object,
                    SyntheticField domainField,
                    Object domainObject,
                    String... tags)
             throws JTransfoException

tags - tags which indicate which fields can be converted based on MapOnly annotations.

Returns:

converted object

Throws:

JTransfoException - problem during type conversion

reverse

TO_TYPE reverse(DOMAIN_TYPE object,
                SyntheticField toField,
                Object toObject,
                String... tags)
         throws JTransfoException

Convert a domain object field value to the value for the transfer object.

Parameters:

object - object to convert

toField - target transfer object field

toObject - target transfer object
