public int read() throws java.io.IOException
Subclasses that intend to support efficient single-character input should override this method.

ch
- Destination bufferoffset
- Offset at which to start storing characterslength
- Maximum number of characters to readpublic long skip(long n) throws java.io.IOException

readAheadLimit
- Limit on the number of characters that may be
read while still preserving the mark. After
