Guava学习之CharSequenceReader

[CharSequenceReader](http://www.iteblog.com/archives/tag/charsequencereader "查看CharSequenceReader中的全部文章")类是以CharSequence的形式读取字符。[CharSequenceReader](http://www.iteblog.com/archives/tag/charsequencereader "查看CharSequenceReader中的全部文章")类继承自Reader类，除了remaining()、hasRemaining()以及checkOpen()函数之后，其他的函数都是重写Reader类中的函数。 [CharSequenceReader](http://www.iteblog.com/archives/tag/charsequencereader "查看CharSequenceReader中的全部文章")类声明没有用public关键字，所以我们暂时还不能调用这个类 CharSequenceReader类有下面三个成员变量 <table border="0" cellpadding="0" cellspacing="0" style="width: 692.7272338867188px;
