Overrides:

decode in class javax.faces.render.Renderer

queueComponentEventForBehaviorEvent

protected void queueComponentEventForBehaviorEvent(javax.faces.context.FacesContext context,
                                                   javax.faces.component.UIComponent component,
                                                   String eventName)

preDecode

protected void preDecode(javax.faces.context.FacesContext context,
                         javax.faces.component.UIComponent component)

preEncodeBegin

protected void preEncodeBegin(javax.faces.context.FacesContext context,
                              javax.faces.component.UIComponent component)
                       throws IOException

Throws:

IOException

encodeBegin

public void encodeBegin(javax.faces.context.FacesContext context,
                        javax.faces.component.UIComponent component)
                 throws IOException

Overrides:

encodeBegin in class javax.faces.render.Renderer

Throws:

IOException

encodeChildren

public void encodeChildren(javax.faces.context.FacesContext context,
                           javax.faces.component.UIComponent component)
                    throws IOException

Overrides:

encodeChildren in class javax.faces.render.Renderer

Throws:

IOException

encodeEnd

public void encodeEnd(javax.faces.context.FacesContext context,
                      javax.faces.component.UIComponent component)
               throws IOException

Overrides:

encodeEnd in class javax.faces.render.Renderer

Throws:

IOException

getSkin

protected org.richfaces.skin.Skin getSkin(javax.faces.context.FacesContext context)

Calculate current Skin for rendering.

Parameters:

context - - current FacesContext

Returns:

getUtils

public RendererUtils getUtils()

Due to big number of common utility methods, base renderer divide to 2 classes - renderer and utils. since use static methods of utility class breack object paradigm, we use getter for concrete util instance. Developer can override any utility metod in 2 stages : 1) Create subclass of RendererUtils and override utility method. 2) Override this method for return instance of such subclass.

Returns:

Returns the utils.

getComponentClass

protected Class<? extends javax.faces.component.UIComponent> getComponentClass()

Get base component slass , targetted for this renderer. Used for check arguments in decode/encode.

Returns:

doDecode

protected void doDecode(javax.faces.context.FacesContext context,
                        javax.faces.component.UIComponent component)

Template method for custom decoding of concrete renderer. All parameters checking if performed in original decode method.

Parameters:
