    • 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()

    • 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()

      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

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

    • 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:

    • 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
