public class WrappedDataOutputStreamPlus
extends UnbufferedDataOutputStreamPlus

When possible use WrappedDataOutputStreamPlus instead of this class, as it will be more efficient when using Plus methods. This class is only for situations where it cannot be used. The channel provided by this class is just a wrapper around the output stream.

Method Detail

write

public void write(byte[] buffer,
                  int offset,
                  int count)
           throws java.io.IOException

Description copied from class: UnbufferedDataOutputStreamPlus

Writes count bytes from the byte array buffer starting at offset to this RandomAccessFile starting at the current file pointer..

Specified by:

write in interface java.io.DataOutput

Specified by:

write in class UnbufferedDataOutputStreamPlus

Parameters:

buffer - the bytes to be written

offset - offset in buffer to get bytes

count - number of bytes in buffer to write

Throws:

java.io.IOException - If an error occurs attempting to write to this RandomAccessFile.

write

public void write(int oneByte)
