Agent mode (proxy pattern) not using proxy mode

If you need to monitor certain states of the (monitor) class, you need to write a monitoring class and monitor the monitoring class.

But only locally, if remote monitoring is required, use proxy pattern.

Specific methods:

1. The class needs to provide state information and provide some get methods to make the call.

/** * @time July 11, 2014 * * Package proxy; /** * @author C.l.wang * */public class Gumballmachine {String location;//Location Information Stat  
    e soldoutstate;  
    State noquarterstate;  
    State hasquarterstate;  
    State soldstate;  
          
    State winnerstate;  
    state state = Soldoutstate;  
          
    int count = 0; /** * */Public Gumballmachine (String location, int numbergumballs) {//TODO auto-generated Co  
        Nstructor stub soldoutstate = new Soldoutstate (this);  
        Noquarterstate = new Noquarterstate (this);  
        Hasquarterstate = new Hasquarterstate (this);  
        Soldstate = new Soldstate (this);  
              
        Winnerstate = new Winnerstate (this);  
              
        this.location = location;  
        This.count = Numbergumballs;  
        if (Numbergumballs > 0) {state = Noquarterstate; }} public void InseRtquarter () {state.insertquarter ();  
    public void Ejectquarter () {state.ejectquater ();  
        public void Turncrank () {State.turncrank ();  
    State.dispense ();  
    public void SetState (state state) {this.state = state;  
        The public void Releaseball () {System.out.println ("A Gumball comes rolling out the slot ...");  
    if (count!= 0) count-;  
    public int GetCount () {return count;  
        public void refill (int count) {This.count = count;  
    state = Noquarterstate;  
    Public State getState () {return state;  
    Public String getLocation () {return location;  
    Public State getsoldoutstate () {return soldoutstate; Public State getnoquarterstate () {return noquarterstate;  
    Public State gethasquarterstate () {return hasquarterstate;  
    Public State getsoldstate () {return soldstate;  
    Public State getwinnerstate () {return winnerstate;  
        Public String toString () {stringbuffer result = new StringBuffer ();  
        Result.append ("\nmighty Gumball, Inc.");  
        Result.append ("\njava-enabled Standing gumball Model #2004 \ n");  
        Result.append ("Inventory:" + count + "Gumball");  
        if (count!= 1) {result.append ("s");  
        } result.append ("\nmachine is" + state + "\ n");  
    return result.tostring (); }  
}

2. Monitor class, call get method, monitor output.

/** 
 * @time July 12, 2014 * *
package proxy;  
      
/** 
 * @author C.l.wang 
 * 
 *
/public class Gumballmonitor {  
      
    gumballmachine machine;  
          
    /** 
     * */Public
    Gumballmonitor (Gumballmachine machine) {  
        //TODO auto-generated constructor stub< C15/>this.machine = machine;  
    }  
          
    public void () {  
        System.out.println ("Gumball Machine:" + machine.getlocation ());  
        System.out.println ("Current inventory:" + machine.getcount () + "gumballs.");  
        System.out.println ("Current state:" + machine.getstate ());  
    }

4. Test class, instantiate specific class, and use monitoring class to monitor.

/** 
 * @time July 11, 2014 * *
package proxy;  
      
/** 
 * @author C.l.wang * */Public
class Gumballmachinetestdrive {  
      
    /** 
     * @param args 
     * * Public
    static void Main (string[] args) {  
        //TODO auto-generated method stub  
        Gumballmachine Gumballmachine = new Gumballmachine ("Seattle");  
        Gumballmonitor gumballmonitor = new Gumballmonitor (gumballmachine);  
        Gumballmonitor.report ();  
    }  
      

5. Output:

Gumball machine:seattle current  
inventory:115 gumballs.  
Current state:waiting for quater
