The Expression retrieves the next root-level band that will be printed and uses this band as parameter for the AbstractElementFormatFunction.processRootBand(org.jfree.report.Band) method. author:    Thomas Morgner Constructor Summary protected   AbstractElementFormatFunction()      Creates an unnamed function. Method Summary public  String getElement()      Returns the element name. public  Object getValue()      Format-Functions usually are not expected to return anything. public  void groupFinished(ReportEvent event)      Processes the group footer of the current group. public  void groupStarted(ReportEvent event)      Processes the group header of the current group. public  void itemsAdvanced(ReportEvent event)      Processes the ItemBand. public  void itemsStarted(ReportEvent event)      Processes the No-Data-Band. public  void pageFinished(ReportEvent event)      Processes the page footer. public  void pageStarted(ReportEvent event)      Processes the page header. abstract protected  void processRootBand(Band b)      Processes the root band for the current event. public  void reportFinished(ReportEvent event)      Processes the Report-Footer. public  void reportStarted(ReportEvent event)      Processes the Report-Header. public  void setElement(String name)      Sets the element name. Constructor Detail AbstractElementFormatFunction protected AbstractElementFormatFunction()(Code) Creates an unnamed function. Make sure the name of the function is set using AbstractElementFormatFunction.setName before the function is added to the report's function collection. Method Detail getElement public String getElement()(Code) Returns the element name. The element name. See Also:   AbstractElementFormatFunction.setElement(String) getValue public Object getValue()(Code) Format-Functions usually are not expected to return anything. null, as format functions do not compute values. groupFinished public void groupFinished(ReportEvent event)(Code) Processes the group footer of the current group. Parameters:   event - the event. groupStarted public void groupStarted(ReportEvent event)(Code) Processes the group header of the current group. Parameters:   event - the event. itemsAdvanced public void itemsAdvanced(ReportEvent event)(Code) Processes the ItemBand. Parameters:   event - the event. itemsStarted public void itemsStarted(ReportEvent event)(Code) Processes the No-Data-Band. Parameters:   event - the report event. pageFinished public void pageFinished(ReportEvent event)(Code) Processes the page footer. Parameters:   event - the event. pageStarted public void pageStarted(ReportEvent event)(Code) Processes the page header. Parameters:   event - the event. processRootBand abstract protected void processRootBand(Band b)(Code) Processes the root band for the current event. This method must be implemented by all subclasses and contains all code necessary to update the style or structure of the given band. The update must be deterministic, calls must result in the same layout for all calls for a given report processing state. Parameters:   b - the band. reportFinished public void reportFinished(ReportEvent event)(Code) Processes the Report-Footer. Parameters:   event - the event. reportStarted public void reportStarted(ReportEvent event)(Code) Processes the Report-Header. Parameters:   event - the event. setElement public void setElement(String name)(Code) Sets the element name. The name denotes an element or band within the root-band or the root-band itself. It is possible to define multiple elements with the same name to apply the modification to all of these elements. Parameters:   name - The element name.
