Constructor Detail

BufferedRandomAccessFile

public BufferedRandomAccessFile(java.io.File file,
                        java.lang.String mode)
                         throws java.io.IOException

Invariant: the current file position = bufferOffset + bufferPosition. This position is always stored inside the buffer, or this position is the byte after the current buffer (in which case the next read will re-fill the buffer.

Throws:

java.io.IOException
