1.分页类

复制代码 代码如下:

package org.zh.basic;

/**

public class pageinfo {

    // 定义
    private string p_tablename; // -表名
    private string p_strwhere; // --查询条件
    private string p_ordercolumn; // --排序的列
    private string p_orderstyle; // --排序方式
    private int p_curpage; // --当前页
    private int p_pagesize; // --每页显示记录条数
    private int p_totalrecords; // --总记录数
    private int p_totalpages; // --总页数

    // / <summary>
    // / 定义函数
    // / </summary>
    public pageinfo() {
    }

    public pageinfo(string p_tablename, string p_strwhere,
            string p_ordercolumn, string p_orderstyle, int p_curpage,
            int p_pagesize, int p_totalrecords, int p_totalpages) {
        this.p_tablename = p_tablename;
        this.p_strwhere = p_strwhere;
        this.p_ordercolumn = p_ordercolumn;
        this.p_orderstyle = p_orderstyle;
        this.p_curpage = p_curpage;
        this.p_pagesize = p_pagesize;
        this.p_totalrecords = p_totalrecords;
        this.p_totalpages = p_totalpages;
    }

    public string getp_tablename() {
        return p_tablename;
    }

    public void setp_tablename(string ptablename) {
        p_tablename = ptablename;
    }

    public string getp_strwhere() {
        return p_strwhere;
    }

    public void setp_strwhere(string pstrwhere) {
        p_strwhere = pstrwhere;
    }

    public string getp_ordercolumn() {
        return p_ordercolumn;
    }

    public void setp_ordercolumn(string pordercolumn) {
        p_ordercolumn = pordercolumn;
    }

    public string getp_orderstyle() {
        return p_orderstyle;
    }

    public void setp_orderstyle(string porderstyle) {
        p_orderstyle = porderstyle;
    }

    public int getp_curpage() {
        return p_curpage;
    }

    public void setp_curpage(int pcurpage) {
        p_curpage = pcurpage;
    }

    public int getp_pagesize() {
        return p_pagesize;
    }

    public void setp_pagesize(int ppagesize) {
        p_pagesize = ppagesize;
    }

    public int getp_totalrecords() {
        return p_totalrecords;
    }

    public void setp_totalrecords(int ptotalrecords) {
        p_totalrecords = ptotalrecords;
    }

    public int getp_totalpages() {
        return p_totalpages;
    }

    public void setp_totalpages(int ptotalpages) {
        p_totalpages = ptotalpages;
    }

}
