包路径：org.eclipse.jdt.core.ToolFactory
类名称：ToolFactory
方法名：createDefaultClassFileReader

ToolFactory.createDefaultClassFileReader介绍

[英]Create a default classfile reader, able to expose the internal representation of a given classfile according to the decoding flag used to initialize the reader. Answer null if the input stream contents cannot be retrieved The decoding flags are described in IClassFileReader.
[中]创建一个默认类文件读取器，能够根据用于初始化读取器的解码标志公开给定类文件的内部表示。回答null如果无法检索输入流内容，则解码标志在IClassFileReader中描述。
