IlvHitmapDefinition (Rogue Wave JViews 9.1 API)

java.lang.Object
- ilog.views.servlet.IlvHitmapDefinition

All Implemented Interfaces:

IlvHitmapConstants
```
public class IlvHitmapDefinition
extends Object
implements IlvHitmapConstants
```
This class generates hitmap relation information such as tooltips. Programmers can override this class to customize the tooltips generated for graphic objects. See IlvManagerServlet for how to install customized hitinfo manager.
This class is designed to be used in the following way:
1. Call init(IlvManagerView) before rendering the hitmap.
2. Call addGraphic(IlvGraphic) to add graphic objects their hitmap information and tooltips will be generated.
3. Call renderHitmap() to render the hitmap for all the graphic objects added.
4. Call dispose() to release resources allocated.
When customizing the tooltip generation, you need to override the getTooltip(IlvGraphic) method to return the customized tooltip. Since JViews 8.8, we introduce a new hitmap information structure, so we can call registerHitmapInfoGenerator(String, IlvHitmapInfoGenerator) to extend the hitmap information. There is a default abstract hitmap infor implementation IlvAbstractHitmapInfoGenerator. We can define a subclass of IlvAbstractHitmapInfoGenerator to customize hitmap information.
Since:

JViews 8.7

    Code example:
```
 IlvHitmapDefinition hitmapDefinition = getServletSupport().getHitmapSupport().getHitmapDefinition();
 hitmapDefinition.registerHitmapInfoGenerator(IlvHitmapConstants.TOOLTIP_TYPE, new MyTooltipInfoGenerator(hitmapDefinition));
 
```
    Parameters:
    
    infoType - A hitmap information type, such as IlvHitmapConstants.TOOLTIP_TYPE, IlvHitmapConstants.GROUP_TYPE, IlvHitmapConstants.CURSOR_TYPE, or IlvHitmapConstants.NAVIGATION_TYPE.
    
    generator - A hitmap info generator.
