Class ReadOnlyDomainAutomaticTypeConverter

java.lang.Object

org.jtransfo.AbstractToDomainTypeConverter

org.jtransfo.ReadOnlyDomainAutomaticTypeConverter

All Implemented Interfaces:

Named, NeedsJTransfo, TypeConverter<Object,Object>

public class ReadOnlyDomainAutomaticTypeConverter
extends AbstractToDomainTypeConverter
implements Named, NeedsJTransfo

Type converter which only copies linked objects' fields to the transfer object. For converting transfer object to domain, the linked objects are looked up but the fields are not updated. This field automaticall detects if the field to convert is a list and uses ReadOnlyDomainAutomaticListTypeConverter in that case.

String	getName() Get name for the object.
Object	reverse(Object domainObject, SyntheticField toField, Object toObject, String... tags) Convert a domain object field value to the value for the transfer object.
void	setAlwaysNewList(boolean alwaysNewList) Set whether a new list should be used as container for the values.
void	setJTransfo(JTransfo jTransfo) Set jTransfo instance which can be used recursively.
void	setKeepNullList(boolean keepNullList) Set whether null values should be kept (true).
void	setName(String name) Set the name for the type converter.

Specified by:

convert in interface TypeConverter<Object,Object>

Overrides:

convert in class AbstractToDomainTypeConverter

Parameters:

toObject - object to convert

domainField - target domain field

domainObject - target domain object

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

doConvert

public Object doConvert(JTransfo jTransfo,
                        Object toObject,
                        SyntheticField domainField,

setName

public void setName(String name)

Set the name for the type converter.
