Methods Summary
final intgetFlags()

        return mFlags;
public final HeaderItemgetHeaderItem()
Get the {@link HeaderItem} that represents metadata for the row.

return

        return mHeaderItem;
public final longgetId()
Returns a unique identifier for this row. This id can come from one of three places:

  • If {@link #setId(long)} has not been called but the header item is not null, the result of {@link HeaderItem#getId()} is returned.
  • Otherwise {@link ObjectAdapter#NO_ID NO_ID} is returned. 

        if ( (mFlags & FLAG_ID_USE_MASK) == FLAG_ID_USE_HEADER) {
            HeaderItem header = getHeaderItem();
            if (header != null) {
                return header.getId();
