getQDR

public QDR getQDR(DataAccess dataAccess,
                  int flags)

Retrieves a QDR for this ColumnComponentInfo. The QDR identifies the dimension members for the data column for which this ColumnComponentInfo provides information.

For example, say you have the following column header in a crosstab.

Boston		Paris
January 2000	February 2000	January 2000	February 2000

In a ColumnComponentInfo for the first column in the databody that corresponds to this column header, the QDR limits Geography to Boston, and it limits Time to January 2000.

Parameters:

dataAccess - The DataAccess that provided the data for the column that this ColumnComponentInfo describes.

flags - A constant that identifies whether to include page edge information if the QDR is not for the page edge. Valid constants are listed in the See Also section.

Returns:

A QDR that identifies the column of data that this ColumnComponentInfo describes.
