I want to know the difference between row.REFRESH_UNDO_CHANGES | row.REFRES

Question

I want to under stand this statement
row.refresh(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS);I know that refresh method take int
I want to know what is the meaning of this int
and what if I used
row.refresh(row.REFRESH_UNDO_CHANGES);Or
row.refresh(row.REFRESH_FORGET_NEW_ROWS);and When I use the Both what is the meaning of this and how this is executed.

Answer 1

When I searched for Java Bitwise OR " |" I Found that
a | b >>     Means 1 if either bit is 1.
This means this is like boolean operations and 0 means false and 1 means true and it makes logical or.I don't know if this true or no.
but when I tried to make
system.out.println();
I found that
        System.out.println("row.REFRESH_UNDO_CHANGES> "+row.REFRESH_UNDO_CHANGES);
        the result is > 10
        System.out.println("row.REFRESH_FORGET_NEW_ROWS> "+row.REFRESH_FORGET_NEW_ROWS);
        the result is >> 8192
        System.out.println("(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS)> "+(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS));
        the result is >> 8202
        this means this makes addition operation
If I make something like this
        row.refresh(8202);
        is this will make the same operation like
        row.refresh("(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS)> "+(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS));and is it takes the number and make the operation depends on this number. like 10 means row.REFRESH_UNDO_CHANGES.
and is this statement
row.refresh(row.REFRESH_UNDO_CHANGES | row.REFRESH_FORGET_NEW_ROWS);equals to
row.refresh(row.REFRESH_UNDO_CHANGES);
row.refresh(row.REFRESH_FORGET_NEW_ROWS);
