Parameters:

first - index of first row

pageSize - amount of rows do load

sortField - field by which data should be sorted

sortOrder - order by which data should be sorted

filters - filters for data

Returns:

section of data sorted and filtered as given in parameters, and additionally filtered by custom query.

setLatestLoadData

protected void setLatestLoadData(@Nullable
                                 String sortField,
                                 @Nullable
