常见类set/get写法与调用
public class MsgInfo {
/**

*/
public static class Type {
public final static int TEXT = 0; // 文本消息
public final static int IMAGE = 1; // 图片消息

public final static int URL = 4;//URL消息
}
/**
* 消息的方向
*/
public static class Direct {
public final static int SEND = 0; // 发送
public final static int RECEIVE = 1; // 接收
}
/**
* 消息的状态
*/
public static class Status {
public final static int SEND_SUCCESS= 0; // 已发送
public final static int SENDING = 1; // 正在发送
public final static int SEND_FAILED = 2; // 发送失败
public final static int READ = 3; // 已读
public final static int UNREAD = 4; // 未读
}
private long msgId;//消息Id
private String ownerId;//消息属于哪个用户
private String relatedId;//消息关联到哪个用户;
private String body;//消息体
private long time;//消息发送接收时间
private int direct;// 消息的方向
private int status;//消息的状态
private int type;//消息的类型
public MsgInfo() {

/对外使用/
MsgInfo msgInfo = new MsgInfo();
msgInfo.setOwnerId(“100011002”);

msgInfo.setBody(“hello 普通调用”);
msgInfo.setType(MsgInfo.Type.TEXT);

/链式调用/
MsgInfo msgInfo = new MsgInfo();
msgInfo.setOwnerId(“100011002”)
.setRelatedId(“1000110003”)
.setBody(“hello 链式调用”)
.setType(MsgInfo.Type.TEXT)
.setDirect(MsgInfo.Direct.SEND)
.setStatus(MsgInfo.Status.SENDING)
.setTime(System.currentTimeMillis());
两者区别在于
传统写法较对于sdk或者工具类的开发者来说较为简介,便于调试,调用者也能在编译器的帮助下了解该类的属性和方法,但是实现某一功能的流程并不能清晰展示。
链式写法相应增加sdk或者工具类的开发者工作量,但对于调用者而言,逻辑更加清晰与命令,便于代码的维护。
