类名称：Transformer

Transformer介绍

[英]Defines a functor interface implemented by classes that transform one object into another.

A Transformer converts the input object to the output object. The input object should be left unchanged. Transformers are typically used for type conversions, or extracting data from an object.

Standard implementations of common transformers are provided by TransformerUtils. These include method invokation, returning a constant, cloning and returning the string value.
[中]定义由将一个对象转换为另一个对象的类实现的函子接口。
Transformer将输入对象转换为输出对象。输入对象应该保持不变。转换器通常用于类型转换，或从对象中提取数据。
TransformerUtils提供了通用变压器的标准实现。其中包括方法调用、返回常量、克隆和返回字符串值。
