CrosstabTotalPositionEnum getTotalPositionValue()
A group can have a total row/column summing the values for all the entries in the group. E.g. if there is a Year group having Month as a subgroup, the total row/column for the Year group would sum the values for all the years and the total row/column for the Month group would sum the values for all the months of an year.
Possible values for this attribute are:
CrosstabTotalPositionEnum.NONE
- the group will not display a total row/columnCrosstabTotalPositionEnum.START
- the group will display the total row/column before the group rows/columnsCrosstabTotalPositionEnum.END
- the group will display the total row/column at the end of the group rows/columnsJRCrosstabBucket getBucket()
The bucketing information consists of grouping expression and group ordering.
JRCellContents getHeader()
The size of the header cell is computed based on the following rules (only the row header rules are listed, the ones for columns can be deducted by symmetrical duality):
JRCrosstabRowGroup.getWidth()
Should never return null, but empty cell contents instead.
JRCellContents getTotalHeader()
The size of a row group total header is computed based on the following rules:
Should never return null, but empty cell contents instead.
JRVariable getVariable()
Each group in the crosstab has a variable that can be used inside the group header as the current group value. The variable has the same name as the group and the same type as the bucket expression of the group.
boolean hasTotal()
This method is currently equivalent to
getTotalPosition() != Bucket.TOTAL_POSITION_NONE
and is therefore
redundant.
Boolean getMergeHeaderCells()
If the header cell is set to repeat, the sub group should not have a total row/column.
By default the header cell spans across all entries that are part of the group.
