use of org.hisp.dhis.common.DataDimensionalItemObject in project dhis2-core by dhis2.

the class AnalyticsUtils method handleGridForDataValueSet.

/**
 * Prepares the given grid to be converted to a data value set.
 *
 * <ul>
 * <li>Converts data values from double to integer based on the associated
 * data item if required.</li>
 * <li>Adds a category option combo and a attribute option combo column to
 * the grid based on the aggregated export properties of the associated data
 * item.</li>
 * <li>For data element operand data items, the operand identifier is split
 * and the data element identifier is used for the data dimension column and
 * the category option combo identifier is used for the category option
 * combo column.</li>

 * @param params the data query parameters.
