Constructor Detail

JRBaseCrosstab

public JRBaseCrosstab(JRCrosstab crosstab,
                      JRBaseObjectFactory factory,
                      int id)

Method Detail

getMode

public ModeEnum getMode()

Description copied from interface: JRCommonElement

Returns the element transparency mode. The default value depends on the type of the report element. Graphic elements like rectangles and lines are opaque by default, but the images are transparent. Both static texts and text fields are transparent by default, and so are the subreport elements.

Specified by:

getMode in interface JRCommonElement

Overrides:

getMode in class JRBaseElement

getId

public int getId()

Description copied from interface: JRCrosstab

Returns the ID of the crosstab.

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:

getDataset in interface JRCrosstab

Returns:

the input dataset of the crosstab

getRowGroups

public JRCrosstabRowGroup[] getRowGroups()

Description copied from interface: JRCrosstab

Returns the row groups of the crosstab.

Specified by:

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

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElement

visit

public void visit(JRVisitor visitor)

Specified by:

visit in interface JRVisitable

getColumnBreakOffset

public Integer 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

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

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

getElementByKey

public static JRElement getElementByKey(JRCrosstab crosstab,
                                        String key)

getElementByKey

public JRElement getElementByKey(String elementKey)

Description copied from interface: JRCrosstab

Searches for an element inside all crosstab cells.

Specified by:

getElementByKey in interface JRCrosstab

elementKey - the element key

Returns:

the first element having the specified key

getTitleCell

public CrosstabColumnCell getTitleCell()

Returns the title cell, which renders once at the beginning of the crosstab.

Specified by:

getTitleCell in interface JRCrosstab

Returns:

the title cell

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.

getHeaderCell in interface JRCrosstab

Returns:

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

getVariables

public JRVariable[] getVariables()

Description copied from interface: JRCrosstab

Returns the variables defined for the crosstab.

Specified by:

getVariables in interface JRCrosstab

Returns:

variables defined for the crosstab

JRCrosstabGroup.getVariable(), JRCrosstabMeasure.getVariable(), JRCrosstab.VARIABLE_ROW_COUNT, JRCrosstab.VARIABLE_IS_EVEN_ROW, JRCrosstab.VARIABLE_COLUMN_COUNT, JRCrosstab.VARIABLE_IS_EVEN_COLUMN

getRunDirection

public RunDirectionEnum getRunDirection()

Description copied from interface: JRCrosstab

Retrieves the run direction of this crosstab

Specified by:

getRunDirection in interface JRCrosstab

Returns:

a value representing one of the run direction constants in RunDirectionEnum

setRunDirection

public void setRunDirection(RunDirectionEnum runDirection)

Description copied from interface: JRCrosstab

Sets the run direction of the crosstab.

Crosstabs can either be filled from left to right (the default) or from right to left (mainly for reports in RTL languages).

Specified by:

setRunDirection in interface JRCrosstab

Parameters:

runDirection - a value representing one of the run direction constants in RunDirectionEnum

getHorizontalPosition

public HorizontalPosition getHorizontalPosition()

getIgnoreWidth

public Boolean getIgnoreWidth()

Description copied from interface: JRCrosstab

Returns the ignore width flag for the crosstab.

Specified by:

getIgnoreWidth in interface JRCrosstab

Returns:

the ignore width flag, or null is the crosstab does not specify a flag value

See Also:

JRCrosstab.setIgnoreWidth(Boolean)

setIgnoreWidth

public void setIgnoreWidth(Boolean ignoreWidth)

Description copied from interface: JRCrosstab

Set the ignore width crosstab flag.

This flag determines whether the crosstab will break at the width set for the crosstab element, or whether the crosstab is to expand over this width (and over the page width as well).

If this flag is set to true, the crosstab will expand towards the right (or towards the left if the crosstab direction is RTL) as long as it needs to. This would result in crosstab cells being rendered over the page boundary; such elements will be exported by certain grid-based exporters such as the HTML or XLS ones, but will not be visible in export formats that observe the page width, such as the PDF exporter.

The default value of this flag is given by the JRCrosstab.PROPERTY_IGNORE_WIDTH property and the JRParameter.IS_IGNORE_PAGINATION parameter.

Specified by:

setIgnoreWidth in interface JRCrosstab

Parameters:

ignoreWidth - whether the element width is to be ignored by the crosstab, or null if the default setting is to be used

See Also:

JRCrosstab.PROPERTY_IGNORE_WIDTH

getDefaultLineColor

public Color getDefaultLineColor()

Specified by:

getDefaultLineColor in interface JRBoxContainer

getLineBox

public JRLineBox getLineBox()

Specified by:
