setJTransfo

public void setJTransfo(JTransfo jTransfo)

Description copied from interface: NeedsJTransfo

Set jTransfo instance which can be used recursively.

Specified by:

setJTransfo in interface NeedsJTransfo

Parameters:

jTransfo - jTransfo instance

canConvert

public boolean canConvert(Class<?> realToType,
                          Class<?> realDomainType)

Description copied from interface: TypeConverter

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

Specified by:

canConvert in interface TypeConverter<Object,Object>

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

doConvert

public abstract Object doConvert(JTransfo jTransfo,
                                 Object toObject,
                                 SyntheticField domainField,
                                 String... tags)
                          throws JTransfoException

Do the actual conversion.

Parameters:

jTransfo - jTransfo instance in use

toObject - transfer object

domainField - domain object field

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

Returns:

domain object

Throws:

JTransfoException - oops, cannot convert

convert
