示例1: read
/**
* Returns the next character in the filtered stream. If the desired
* number of lines have already been read, the resulting stream is
* effectively at an end. Otherwise, the next character from the
* underlying stream is read and returned.
*
* @param int $len
* @return int|string the next character in the resulting stream, or -1
* if the end of the resulting stream has been reached
*
* @throws IOException if the underlying stream throws an IOException
* during reading
* @throws BuildException
