public class NonEmptyVirtualStorage
This is a BitmapStorage that can be used to determine quickly if the result of an operation is non-trivial... that is, whether there will be at least on set bit.

void |
add(long newdata)
If the word to be added is non-zero, a NonEmptyException exception is thrown. |
void |
addStreamOfEmptyWords(boolean v,
long number)
If the boolean value is true and number is greater than 0, then it throws a NonEmptyException exception, otherwise, nothing happens. |
