public class FlashFileInputStream
extends InputStream

FlashFileInputStream represents an input stream over some flash memory. There are two uses for this.

The first is to stream over the flash memory allocated to an instance of a FlashFile. In this case, you should construct the input stream accordingly, for example:

 FlashFileInputStream ffis = new FlashFileInputStream(new FlashFile("my file"));

In this case, the input stream will signal end of file when the reader reaches the end of the data that has been written to the FlashFile.

The second use of FlashFileInputStream is to stream over the flash memory in an arbitrary sector of the flash memory. In this case, construct the input stream like this:

 FlashFileInputStream ffis = new FlashFileInputStream(new NorFlashSector(mySectorNumber));

In this case, the input stream will signal end of file when the reader reaches the end of the physical sector.
