Remarks

Does a join on two cursors using the specified columns. The cursors must already be sorted on each of the specified columns in ascending order. This joiner only supports the case where the tuple of key column values is unique.

Typical usage:

CursorJoiner joiner = new CursorJoiner(cursorA, keyColumnsofA, cursorB, keyColumnsofB);
            for (CursorJoiner.Result joinerResult : joiner) {
                switch (joinerResult) {
                    case LEFT:
                        // handle case where a row in cursorA is unique
                        break;
                    case RIGHT:
                        // handle case where a row in cursorB is unique
                        break;
                    case BOTH:
                        // handle case where a row with the same key is in both cursors
                        break;
                }
            }
