封装一个jqGrid的数据源类

这2个月刚换单位,比较赶进度.很久不更新blog,今天抽空看了一下jqGrid,因为现在工作环境又迁到java了,但是是1.4的呵呵,所以封装了一个jqGrid的数据源,方便使用

ps: 需要json-simple [url=http://code.google.com/p/json-simple]点我[/url]

package com.javaeye.rikugun.jqGrid;

import java.io.IOException;
import java.io.Writer;
import java.util.LinkedList;
import java.util.List;

import org.json.simple.JSONAware;
import org.json.simple.JSONObject;
import org.json.simple.JSONStreamAware;

/**
 * jqGrid 的数据源类
 * 
 * @author rikugun
 * 
 */
public class JqGridDataSource implements JSONAware, JSONStreamAware {

	private int records = 0;
	private int page = 0;
	private int total = 0;
	private List rows = new LinkedList();
	private JSONObject json = new JSONObject();

	/**
	 * 添加一行记录
	 * 
	 * @param row
	 *            输出的记录
	 * @return 当前数据源,方便链式写法 ds.add("a row").add("other row");
	 */
	public JqGridDataSource addRow(String row) {
		rows.add(row);
		return this;
	}

	/**
	 * 添加一行记录
	 * 
	 * @param obj
	 *            JSON对象,转换成字符串
	 * @return 当前数据源,方便链式写法 ds.add(obj1).add(obj2);
	 */
	public JqGridDataSource addRow(JSONObject obj) {
		rows.add(obj.toJSONString());
		return this;
	}
	/**
	 * 构造json对象
	 */
	private void build() {
		json.put("records", new Integer(records));
		json.put("page", new Integer(page));
		json.put("total", new Integer(total));
		json.put("rows", rows);
	}

	public int getRecords() {
		return records;
	}

	public void setRecords(int records) {
		this.records = records;
	}

	public int getPage() {
		return page;
	}

	public void setPage(int page) {
		this.page = page;
	}

	public int getTotal() {
		return total;
	}

	public void setTotal(int total) {
		this.total = total;
	}

	public List getRows() {
		return rows;
	}

	public void setRows(List rows) {
		this.rows = rows;
	}


	public String toJSONString() {
		build();
		return json.toJSONString();
	}

	public void writeJSONString(Writer out) throws IOException {
		build();
		json.writeJSONString(out);
	}

}

//usage
//..........
Map m = new LinkedHashMap();
m.put("name","rikugun");
m.put("phone","1323xxxxxxx");

JSONObject obj = new JSONObject();
obj.put("name","rikugun1");
obj.put("phone","1323xxxxxxx");

new JqGridDataSource ds = new JqGridDataSource();
ds.setPage(1);
ds.setTotal(1);
ds.add(JSONValue.toJSONString(m));
ds.add(obj);

System.out.println(ds.toJSONString());
//or

ds.writeJSONString(System.out);

//result  {"page":1,"total":1,"records":2,"rows":[{"name":"rikugun","phone":"1323xxxxxxx"},{"name":"rikugun1","phone":"1323xxxxxxx"}]}

回头有空再写个1.5的
