UML图:
本文中的例子是创建Dota模型的例子,英雄和等级低的野怪有什么区别?区别在英雄有技能,等级低的野怪没有技能。下面会是创建模型的过程:
CreateModel(创建3D模型)->SetSkill(设置技能)->SetPosition(设置位置)->Maps(贴图)。
可以看出,除了设置技能外其他的过程都是公用的,所以抽象出模板方法BuildModel,SetSkill方法在子类中实现:
public abstract class Model
{
public void CreateModel()
{
LandpyForm.Form.OutputResult("CreateModel");
}
public abstract void SetSkill();
public void SetPosition()
{
LandpyForm.Form.OutputResult("SetPosition");
}
public void Maps()
{
LandpyForm.Form.OutputResult("Maps");
}
//模板方法
public void BuildModel()
{
CreateModel();
SetSkill();
SetPosition();
Maps();
}
}
SetSkill方法由于英雄和等级低的野怪不同所以由子类来实现:{
public void CreateModel()
{
LandpyForm.Form.OutputResult("CreateModel");
}
public abstract void SetSkill();
public void SetPosition()
{
LandpyForm.Form.OutputResult("SetPosition");
}
public void Maps()
{
LandpyForm.Form.OutputResult("Maps");
}
//模板方法
public void BuildModel()
{
CreateModel();
SetSkill();
SetPosition();
Maps();
}
}
public class Hero : Model
{
public override void SetSkill()
{
LandpyForm.Form.OutputResult("SetSkill");
}
}
public class SmallBotWildNPC : Model
{
public override void SetSkill()
{
LandpyForm.Form.OutputResult("NoSkill");
}
}
测试代码:{
public override void SetSkill()
{
LandpyForm.Form.OutputResult("SetSkill");
}
}
public class SmallBotWildNPC : Model
{
public override void SetSkill()
{
LandpyForm.Form.OutputResult("NoSkill");
}
}
LandpyForm.Form.OutputResult("Hero");
DotaPatternLibrary.TemplateMethod.Model model = new DotaPatternLibrary.TemplateMethod.Hero();
model.BuildModel();
LandpyForm.Form.OutputResult("BotWildNPC");
model = new DotaPatternLibrary.TemplateMethod.SmallBotWildNPC();
model.BuildModel();
完整代码不用贴出,上边的代码均已包括。
以下是变形模板方法,数组排序,包括Framework实现和自己的实现:
