Method Detail

register

public static <T> void register(Class<T> clazz,
                                TypeBinder<T> typeBinder)

Add custom binder for any given class E.g. @{code Binder.register(BigDecimal.class, new MyBigDecimalBinder());} NB! Do not forget to UNREGISTER your custom binder when applications is reloaded (most probably in method onApplicationStop()). Otherwise you will have a memory leak.

Remove custom binder that was add with method #register(java.lang.Class, play.data.binding.TypeBinder)
