Direct Known Subclasses:

BoundedFlashOutputStream

public class FlashOutputStream
extends OutputStream

An OutputStream that streams over flash memory.

Constructor Summary

FlashOutputStream(IFlashMemoryDevice device, int startSectorNum, int numOfSectors)
Create an OutputStream that streams over specified sectors of a flash device

Method Summary

void	flush() Flushes this output stream and forces any buffered output bytes to be written out.

Constructor Detail

FlashOutputStream

public FlashOutputStream(IFlashMemoryDevice device,
                         int startSectorNum,
                         int numOfSectors)

Create an OutputStream that streams over specified sectors of a flash device

Parameters:

device - The memory device

startSectorNum - The first sector to use (zero based)

numOfSectors - The number of sectors to use

Method Detail

write

public void write(int data)
           throws IOException

Description copied from class: OutputStream

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Subclasses of OutputStream must provide an implementation for this method.

Specified by:

write in class OutputStream

Parameters:

data - the byte.

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

flush

public void flush()
           throws IOException

Description copied from class: OutputStream

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

The flush method of OutputStream does nothing.

Overrides:

flush in class OutputStream

Throws:

IOException - if an I/O error occurs.
