Question

我有一个数据表，其中属性之一是字段Vigente。 Vigente是一个可能值为``是''或``否''的枚举。

在数据表中实现一个类型为oneSelectMenu的过滤器列，其中可能的值为All（默认为第一个声明的值），是和否。

有没有办法使默认值成为oneSelectMenu的第三个元素，在这种情况下，是吗？

枚举代码

public enum EnumVigente {
    NO("No"),
    YES("Yes");

   private final String descricao;

    private EnumVigente(String descricao) {
        this.descricao = descricao;
    }

    public String getDescricao() {
        return descricao;
    }
}

bean代码

O bean dele é

@RequestScoped
@ManagedBean
public class EnumVigenteBean implements Serializable {

    public EnumVigente[] getEnumVigentes() {
        return EnumVigente.values();
    }

    public EnumVigente getEnumSim() {
        return EnumVigente.SIM;
    }

    public EnumVigente getEnumNao() {
        return EnumVigente.NAO;
    }
}
