The ID is generated when the report is compiled and is used internally.

Specified by:

getId in interface JRCrosstab

Returns:

the ID of the crosstab

getDataset

public JRCrosstabDataset getDataset()

Description copied from interface: JRCrosstab

Returns the input dataset of the crosstab.

Specified by:

Returns:

the input dataset of the crosstab

getRowGroups

public JRCrosstabRowGroup[] getRowGroups()

Description copied from interface: JRCrosstab

Returns the row groups of the crosstab.

getRowGroups in interface JRCrosstab

Returns:

the row groups

getColumnGroups

public JRCrosstabColumnGroup[] getColumnGroups()

Description copied from interface: JRCrosstab

Returns the column groups of the crosstab.

Specified by:

getColumnGroups in interface JRCrosstab

Returns:

the column groups

getMeasures

public JRCrosstabMeasure[] getMeasures()

Description copied from interface: JRCrosstab

Returns the crosstab measures.

Specified by:

getMeasures in interface JRCrosstab

Returns:

the crosstab measures

getColumnBreakOffset

public int getColumnBreakOffset()

Description copied from interface: JRCrosstab

Returns the column break offset.

When the crosstab columns do not fit the width, the crosstab breaks the columns and prints the ones that don't fit after printing the first set of columns for all rows. This method returns the offset to be used when continuing the printing after a column break.

Specified by:

getColumnBreakOffset in interface JRCrosstab

Returns:

the column break offset

isRepeatColumnHeaders

public boolean isRepeatColumnHeaders()

Description copied from interface: JRCrosstab

Returns whether to repeat the column headers after a row break.

Specified by:

isRepeatColumnHeaders in interface JRCrosstab

Returns:

whether to repeat the column headers after a row break

isRepeatRowHeaders

public boolean isRepeatRowHeaders()

Description copied from interface: JRCrosstab

Returns whether to repeat the row headers after a column break.

Specified by:

isRepeatRowHeaders in interface JRCrosstab

Returns:

whether to repeat the row headers after a column break

getCells

public JRCrosstabCell[][] getCells()

Description copied from interface: JRCrosstab

Returns the data cell matrix.

A crosstab can have multiple data cells for row/groups totals. These cells are organized in a (rowGroupCount + 1) x (columnGroupCount + 1) matrix as following:

• the row index of a cell is
  • the row group index, if the cell corresponds to a total row
  • rowGroupCount, otherwise
• the column index of a cell is
  • the column group index, if the cell corresponds to a total column
  • columnGroupCount, otherwise

E.g. if the crosstab has Country and City (subgroup of Country) row groups and Year and Month column groups, the cells will be organized in the following matrix

	0/Years total	1/Months total	2/Base
0/Countries total	Total for all countries and all years	Total for all countries and a year	Total for all countries and a month
1/Cities total	Total for a country and all years	Total for a country and a year	Total for a country and a month
2/Base	Total for a city and all years	Total for a city and a year	Total for a city and a month

If the data cell for a total row/column is not specified, the cell will be inherited from lower levels, if possible. For example, if the "Total for all countries and a year" cell is not specified, the "Total for a country and a year" or "Total for a city and a year" cell will be used (in this order).

The data cell sizes are calculated from the base data cell sizes, i.e. the height of all data cells for a row will be the height of the base cell of that row. The base cell sizes are also inherited, e.g. if the height of a total row is not specified the height of the base row will be used.

Specified by:

getCells in interface JRCrosstab

Returns:

the data cell matrix

getWhenNoDataCell

public JRCellContents getWhenNoDataCell()

Description copied from interface: JRCrosstab

Returns a cell which will be rendered when no data was fed to the crosstab.

If this cell is not specified for a crosstab, nothing will be rendered for an empty crosstab.

The cell sizes are the same as the crosstab element sizes.

Specified by:

getWhenNoDataCell in interface JRCrosstab

Returns:

a cell which will be rendered when no data was fed to the crosstab

getParameters

public JRCrosstabParameter[] getParameters()

Description copied from interface: JRCrosstab

Returns the crosstab parameters.

Crosstabs have separate expression evaluators and cannot access the parameters/fields/variables of the report. In order to use a value from the report inside a crosstab, it should be passed as parameter to the crosstab.

A crosstab parameters has a name and a value expression.

Specified by:

getParameters in interface JRCrosstab

Returns:

the crosstab parameters

getParametersMapExpression

public JRExpression getParametersMapExpression()

Description copied from interface: JRCrosstab

Returns the parameters map expression.

The set of values for crosstab parameters can be set using a map. If a parameter has also a value expression, it will overwrite the value from the map.

Specified by:

getParametersMapExpression in interface JRCrosstab

Returns:

the parameters map expression

getElementByKey

public JRElement getElementByKey(java.lang.String elementKey)

Description copied from interface: JRCrosstab

Searches for an element inside all crosstab cells.

Specified by:

getElementByKey in interface JRCrosstab

Parameters:

elementKey - the element key

Returns:

the first element having the specified key

createClone

public JRFillCloneable createClone(JRFillCloneFactory factory)

Description copied from interface: JRFillCloneable

Creates a working clone of itself.

Specified by:

createClone in interface JRFillCloneable

Parameters:

factory - the clone factory to use while creating the clone

Returns:

a working clone of itself

getHeaderCell

public JRCellContents getHeaderCell()

Description copied from interface: JRCrosstab

Returns a cell which will be rendered at the upper-left corner of the crosstab.

The cell size will be calculated based on the row/column header cell widths/heights.

Specified by:

getHeaderCell in interface JRCrosstab

Returns:

a cell which will be rendered at the upper-left corner of the crosstab

getVariables

public JRVariable[] getVariables()
