Constructor Detail

QueryAxis

public QueryAxis(boolean nonEmpty,
                 Exp set,
                 AxisOrdinal axisOrdinal,
                 QueryAxis.SubtotalVisibility subtotalVisibility,
                 Id[] dimensionProperties)

Creates an axis.

Parameters:

nonEmpty - Whether to filter out members of this axis whose cells are all empty

set - Expression to populate the axis

axisOrdinal - Which axis (ROWS, COLUMNS, etc.)

subtotalVisibility - Whether to show subtotals

dimensionProperties - List of dimension properties
