Constructor Summary

FileOutputStream(File f)
create a new OutputStream to write to this file, starting at the beginning of the file.

FileOutputStream(File f, boolean append)
create a new OutputStream to write to this file

Method Summary

void	close() Write the buffer to flash memory and update the file parameters in flash.
void	flush() Flushes this output stream and forces any buffered output bytes to be written out.
void	write(int b) write 1 byte to the file; if necessary, file will be moved become the last file in memory

Constructor Detail

FileOutputStream

public FileOutputStream(File f)

create a new OutputStream to write to this file, starting at the beginning of the file.

Parameters:

f - the file this stream writes to

FileOutputStream

public FileOutputStream(File f,
                        boolean append)

create a new OutputStream to write to this file

Parameters:

f - the file this stream writes to

append - if true this sream will start writing at the end of the file, otherwise at the beginning

Method Detail

write

public void write(int b)
           throws IOException

write 1 byte to the file; if necessary, file will be moved become the last file in memory

Specified by:

write in class OutputStream

Parameters:

b - 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.

close

public void close()
           throws IOException

Write the buffer to flash memory and update the file parameters in flash. Resets pointers, so file can be writen again from beginning with the same output stream.

Overrides:

close in class OutputStream

Throws:

IOException - if an I/O error occurs.
