Type Parameters:

TO_TYPE - type in transfer object

DOMAIN_TYPE - type in domain object

All Known Implementing Classes:

AbstractListTypeConverter, AbstractToDomainTypeConverter, ListTypeConverter, MappedBy.DefaultTypeConverter, NoConversionTypeConverter, ReadOnlyDomainListTypeConverter, ReadOnlyDomainTypeConverter, StringEnumTypeConverter, ToDomainTypeConverter

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

boolean	canConvert(Class<?> realToType, Class<?> 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(Class<?> realToType,
                   Class<?> 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

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

Parameters:

object - object to convert

domainObject - target domain object

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

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