Identifying the Renderer Type

During the render response phase, the JavaServer Faces implementation calls the getRendererType method of the component’s tag handler to determine which renderer to invoke, if there is one.

The getRendererType method of AreaTag must return the type associated with AreaRenderer. You identify this type when you register AreaRenderer with the render kit, as described in Registering a Custom Renderer with a Render Kit. Here is the getRendererType method from the AreaTag class:

public String getRendererType() { return ("DemoArea");}

Creating the Component Tag Handler explains more about the getRendererType method.
