Method Detail

read

int read()
  throws IOException

Reads a single int from the channel, or throws EOFException if no data is left.

Returns:

The next integer read

Throws:

EOFException - If no data remains in the channel

IOException - If some other IO error occurs.

read

default int read(IntBuffer buffer)
          throws IOException

Reads into the given buffer. The default implementation continually calls {code #read()} until the buffer is full or no more data is available. Implementing classes are encouraged to override this with something more efficient where possible.

Parameters:

buffer - The buffer into which the data will be read.

Returns:

The number of ints read, or -1 if end of file reached before any data was transferred.

Throws:

IOException
