* Is used to synchronized properties between two objects.
* Beans binding now fully support matisse GUI Builder (make
easier for developer for binding data).
* There are binding source and target.
* Update strategies: Read/Write, Read-Only, Read-Once
* If you want to synchronize properties of two objects but they
have different types you have to create Converter.
* Use Validator to filter binding’s value from target.
* General Data flow
Converter
Source
Target
Validator
Converter
* Extends org.jdesktop.beansbinding.Converter<S,T>
to
create new Converter. S is source type, and T is target type.
* Override convertForward(S value):T to converts a value from
the source type to the target type.
* Override convertReverse(T value):S to converts a value from
the target type to the source type.
