Package org.aoju.bus.core.builder

Class ReflectionBuilder

java.lang.Object

org.aoju.bus.core.builder.ReflectionBuilder

All Implemented Interfaces:

Serializable, Builder<DifferentResult>

public class ReflectionBuilder
extends Object
implements Builder<DifferentResult>

协助实现Differentable.diff(Object)方法.

使用反射发现要差异的对象的所有非静态、非瞬态字段(包括继承字段)，并比较它们之间的差异.

 public class Person implements Diffable<Person> {
   String name;
   int age;
   boolean smoker;
   ...

   public DiffResult diff(Person object) {
     return new ReflectionDiffBuilder(this, object, ToStringStyle.SHORT_PREFIX_STYLE)
       .build();
   }
 }
 

传递给构造函数的ToStringStyle嵌入到返回的DiffResult中， 并影响DiffResult. tostring()方法的风格。可以通过调用 DifferentResult.toString(ToStringStyle)覆盖此样式选择.

ReflectionBuilder

public ReflectionBuilder(T lhs,
 T rhs,
 ToStringStyle style)

使用指定样式为指定对象构造一个生成器

如果lhs == rhs或lhs.equals(rhs)， 则构建器将不计算对append(…)的任何调用， 并在build()执行时返回一个空的DifferentResult.

Type Parameters:

T - 要区分的对象的类型

Parameters:

lhs - this 对象

rhs - 反对的对象

style - 当输出对象时将使用该样式，null使用默认值

Method Details

build

public DifferentResult build()

Description copied from interface: Builder

包装唯一键（System.identityHashCode()）使对象只有和自己 equals 此对象用于消除小概率下System.identityHashCode()产生的ID重复问题

Specified by:

build in interface Builder<DifferentResult>

Returns:

被构建的对象
