read

public int read()
         throws IOException

Returns the next byte in the stream.

Specified by:

read in class InputStream

Returns:

IOException - An I/O error occurred.

close

public void close(boolean pCloseUnderlying)
           throws IOException

Closes the input stream.

Parameters:

pCloseUnderlying - Whether to close the underlying stream (hard close)

IOException - An I/O error occurred.

skip

public long skip(long bytes)
          throws IOException

Skips the given number of bytes.

Overrides:

skip in class InputStream
