Class Overview

The ReportGridCellColHeaderImpl is used to generate the HTML of a cell of that is a value of the column axis.

This class can handle two different types of SDK objects:
  1. WebHeader: used in view mode, this is the SDK object that represents a value of the column axis.
  2. WebTemplateMetric: used in design mode when the metrics are located in the column axis, each metric is represented as a column header.

The ReportGridCellColHeaderImpl extends the AbstractReportGridDisplayCell which controls the exeuction flow.

Users who intend to programatically modify the HTML generated for a column header should extend this class. Using this technique developers could define their own rules of the text to display based on the WebHeader content.

The following is an example of a class that extends the generateText(MarkupOutput) method of this class based on the header's semantics: 
 public class CustomColHeader extends ReportGridCellColHeaderImpl {

     public void generateText(MarkupOutput mo) {
         WebHeader header = getWebHeader();

         if (header != null) {
             switch (header.getSemantics()) {
             case EnumDSSXMLBaseFormType.DssXmlBaseFormPicture:
                 mo.append("<IMG SRC=\"");
                 mo.append(getText());
                 mo.append("\" ALT=\"\" BORDER=0 />");
                 break;

             case EnumDSSXMLBaseFormType.DssXmlBaseFormUrl:
             case EnumDSSXMLBaseFormType.DssXmlBaseFormEmail:
                 mo.append("<A HREF=\"");
                 if (header.getSemantics() == EnumDSSXMLBaseFormType.DssXmlBaseFormEmail) mo.append("mailto:");
                 mo.append(getText());
                 mo.append("\">");
                 mo.append(getText());
                 mo.append("</A>");
                 break;

             case EnumDSSXMLBaseFormType.DssXmlBaseFormHTMLTag:
                 mo.append(HTMLHelper.decode(getText()));
                 break;

             default:
                 super.generateText(mo);
                 break;
             }
         } else {
             super.generateText(mo);
         }
     }
 }

Therefore, it saves a lot of memory. For implementation of this method, please follow the workflow of how all the instance variables are initialized in the class hierarchy when a new instance is created: superclass instance variables are initialized first, subclass instance variables are initialized second. Note: for the purpose of cell reuse.

This method is deprecated.
Please use the new approach for generating context menus, see ReportCellRemoveFromGrid, ReportCellMove, etc

protected void generateDrillCheckBox (MarkupOutput mo)

Obtains the check box tag information for Drill and renders it out. If a check box is rendered, an empty line is also added to the final HTML output.

Parameters
mo MarkupOutput instance where the HTML content generated by this method will be saved

protected void generateFilterOnSelectionCheckBox (MarkupOutput mo)

Obtains the check box tag information for Filter On Selection and renders it out. If a check box is rendered, an empty line is also added to the final HTML output.

Parameters
mo MarkupOutput instance where the HTML content generated by this method will be saved

protected Tag generatePivotButton (int type)

Generate the pivot button tag, according to the type of manipulation that should perform

Parameters
type integer value that indicates which type of pivot action it should execute. Values come from the PIVOT_INCREASE_POSITION, PIVOT_DECREASE_POSITION and PIVOT_REMOVE constants.
Returns
  • Tag initialized instance with the information for the pivot manipulation. It will return null if not supported. It might return a simple IMG tag in case the manipulation shall be processed in JavaScript, or an INPUT of type IMAGE if it will be processed as part of a FORM, or an A anchor tag with an IMG inside if it's to be a button link.

protected void generatePivotButtons (MarkupOutput mo)

Calls for generatePivotButton(int) for each one of the buttons this instance normally supports

Parameters
mo MarkupOutput instance where the HTML generated by this method will be saved.

protected void generatePreContent (MarkupOutput mo)

By default, this method generates images for grids in outline mode, drilling checkboxes and filter on selection checkboxes.

Developers can either use the setPreContent(String) method to set any text they want to display before the contents of the cell or override this method to inherit its functionality and build on top of it.

For example, the following code could be used to extend this method to add a <LI> tag before the cell content in any of the classes that extend AbstractReportGridDisplayCell:
 public void generatePreContent(MarkupOutput mo) {
     super.generatePreContent(mo);

     mo.append("<LI>");
 }

Parameters
mo the output object

protected Tag generateSortButton ()

Generate the sort button tag information for this object
