Examples of java.io.PushbackReader.unread()

java.io.PushbackReader.unread()
Push back all the chars in buffer. The chars are pushed so that they would be read back buffer[0], buffer[1], etc. If the push back buffer cannot handle the entire contents of buffer, an IOException will be thrown. Some of the buffer may already be in the buffer after the exception is thrown. @param buffer the char array containing chars to push back into the reader. @throws IOException If the pushback buffer becomes, or is, full.
