Package systextil.nxj

Class FieldAdapter

java.lang.Object
systextil.nxj.FieldAdapter
All Implemented Interfaces:
FieldListener
public class FieldAdapter extends Object implements FieldListener
Conveniência para implementar somente os métodos de FieldListener que se desejar. Todos os métodos já estão implementados com base no listener informado. Se não for informado nenhum, é usado FieldListener.EMPTY.

É interessante para componentes do NXJ que desejem registrar seus eventos para uso pelas classes controller, com opção para sobrescrever eventos já existentes.

Se for usado o construtor padrão, não há necessidade dos métodos sobrescritos chamarem super, pois o listener usado não implementa nenhum evento.
