Class BinderFactory

java.lang.Object

org.nuiton.util.beans.BinderFactory

public class BinderFactory
extends Object

Factory of Binder.

Obtain a new binder

To obtain a new binder you can use the newBinder(XXX) methods. For example to obtain a mirrored binder (same source and target type) which will be able to copy all accepting properties, use this code :

 Binder<BeanA, BeanA> binder = BinderFactory.newBinder(BeanA.class);
 

Usage of contextale binder

It is possible to use different binder for same source and target type, using a extra context name parameter, like this :

 Binder<BeanA, BeanA> binder = BinderFactory.newBinder(BeanA.class, "mycontext");
 

This is usefull when you register your own binder model in the factory (see next section) to bind different things from the same type of objects...

Register a new binder model

To register a new binder's model use one of the method registerBinderModel(XXX). More documentation will come soon, yu can see the package info javadoc or unit tests...

Since:

1.5.3
