public class CharSequenceReader
extends java.io.Reader
implements java.io.Serializable
Reader implementation that can read from String, StringBuffer,
StringBuilder, CharBuffer or GString.
Note: Supports mark(int) and reset().
Note: This class is mostly a copy from Commons IO and is intended for internal Groovy usage only. It may be deprecated and removed from Groovy at a faster pace than other classes. If you need this functionality in your Groovy programs, we recommend using the Commons IO equivalent directly.
