Class Overview

The ReportGridCellMetricValue is used to generate the HTML of a cell value of the report data.

It uses a WebRowValue as the underlying SDK objects to retrieve the information from.

The ReportGridCellColTitleImpl extends the AbstractReportGridDisplayCell which controls the exeuction flow.

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

The following is an example of a class that extends the generateText(MarkupOutput) method of this class based on the title's template unit type: 
 public class CustomMetricValueextends ReportGridCellMetricValueImpl {
     public void generateText(MarkupOutput mo) {

         WebRowValue rowValue = getWebRowValue();

         if (rowValue != null) {
             String spanPrefix = "";
             String spanPostfix = "";

             switch (rowValue.getSemantics()) {
             case EnumDSSXMLBaseFormType.DssXmlBaseFormPicture:
             case EnumDSSXMLBaseFormType.DssXmlBaseFormUrl:
                 //For threshold images
                 Tag imgTag = TagsFactory.getInstance().newTag("img");

                 imgTag.setAttribute(EnumHTMLTags.ATT_SRC, rowValue.getValue());
                 imgTag.render(mo);

                 break;

             case EnumDSSXMLBaseFormType.DssXmlBaseFormSymbol:
                 //For thresholds quick symbols
                 generateThresholdSymbol(mo, Integer.parseInt(rowValue.getValue()));
                 break;

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

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

This method is called to initialize the cell with the corresponding WebRowValue as the underlying SDK object.

Parameters
wc The bean being transformed.
rowValue The WebRowValue corresponding to this cell.
cachedObjects A HashMap populated by the transform and used to store information shared across multiple cells.

public void init (FormalParameters formalParas)

This method is deprecated.
This method is not used by the Transform anymore. To initialize empty cells it now uses init(TransformContext).

Initializes an ReportGridDisplayCell. This is used to initialize empty cells that have no underlying WebObject.

Parameters
formalParas all the formal parameters from the report transform. Used to control some output generation.

public void reset ()

Reset all of the instance variables. This method is very important when improve the memory performance: we create only one instance for a particular cell type and reuse it instead of creating a new instance for each concrete grid cell. 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.
