Method Details

hasMoreBytes

boolean hasMoreBytes()
              throws IOException

Method to call to check if more input is available. Since this may result in more content to be read (at least one more byte), a IOException may get thrown.

Returns:

Whether there is at least one more input byte accessible

Throws:

IOException - If check for more content failed due to issue with underlying input abstraction

nextByte

byte nextByte()
       throws IOException

Returns next byte available, if any; if no more bytes are available, will throw EOFException.

Returns:

Next content byte, if available

Throws:

IOException - If called and there is no more content available

reset
