getRendererType

public String getRendererType()

Description copied from class: UIComponentTagBase

Return the rendererType property that selects the Renderer to be used for encoding this component, or null to ask the component to render itself directly. Subclasses must override this method to return the appropriate value.

Specified by:

getRendererType in class UIComponentTagBase

Returns:

the renderer type

getComponentType

public String getComponentType()

Description copied from class: UIComponentTagBase

Return the component type for the component that is or will be bound to this tag. This value can be passed to Application.createComponent(java.lang.String) to create the UIComponent instance for this tag. Subclasses must override this method to return the appropriate value.

Specified by:

getComponentType in class UIComponentTagBase

Returns:

the component type

setProperties

protected void setProperties(UIComponent component)

Description copied from class: UIComponentELTag

Override properties and attributes of the specified component, if the corresponding properties of this tag handler instance were explicitly set. This method must be called ONLY if the specified UIComponent was in fact created during the execution of this tag handler instance, and this call will occur BEFORE the UIComponent is added to the view.

Tag subclasses that want to support additional set properties must ensure that the base class setProperties() method is still called. A typical implementation that supports extra properties foo and bar would look something like this:

 protected void setProperties(UIComponent component) {
   super.setProperties(component);
   if (foo != null) {
     component.setAttribute("foo", foo);
   }
   if (bar != null) {
     component.setAttribute("bar", bar);
   }
 }
 

The default implementation overrides the following properties:

• rendered - Set if a value for the rendered property is specified for this tag handler instance.
• rendererType - Set if the getRendererType() method returns a non-null value.

Overrides:

setProperties in class UIComponentELTag

Parameters:

component - UIComponent whose properties are to be overridden
