Interface PreConverter<T,D>

Type Parameters:

T - type of the transfer object

D - type of the domain object

public interface PreConverter<T,D>

Interceptor which allows additional work to be done just before jTransfo converts between objects.

This is called at the end of the interceptor pipeline, before convertion of the individual fields. The preconverter is only used when it is declared on the transfer object using PreConvert.

The preconverter should be re-entrant. A singleton is used for all convert invocations.

Method Detail

preConvertToTo

default PreConverter.Result preConvertToTo(D source,
