Method Detail

getRendersChildren

public boolean getRendersChildren()

Overrides:

getRendersChildren in class javax.faces.render.Renderer

encodeBegin

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

on create view or in development mode this will build the component tree

Overrides:

encodeBegin in class javax.faces.render.Renderer

Throws:

java.io.IOException

getViewType

protected ViewType getViewType(javax.faces.component.UIComponent startComponent)

determine the current view type

• "list" means: the layout component "is a" or "is embedded in an" list component (UIData)
• "form" means: anything else

findLayoutComponent

protected javax.faces.component.UIComponent findLayoutComponent(DynaForm dynaForm)

findComponentEx

protected javax.faces.component.UIComponent findComponentEx(javax.faces.component.UIComponent base,
                                                            java.lang.String id)

find a component "by id" by simply traversing the tree

collectInputComponents

protected void collectInputComponents(java.util.List<javax.faces.component.UIInput> components,
                                      javax.faces.component.UIComponent baseComponent)

collect all input components recursiv starting with component

addComponents

protected void addComponents(javax.faces.context.FacesContext context,
                             DynaForm dynaForm,
                             javax.faces.component.UIComponent layoutComponent,
                             ViewType viewType)

create and add the components to the layout component

getValueBindingPrefix

protected java.lang.String getValueBindingPrefix(DynaForm dynaForm,
                                                 javax.faces.component.UIComponent layoutComponent)

createGuiBuilder

protected JsfGuiBuilder createGuiBuilder(javax.faces.context.FacesContext facesContext)

processPreviouslyAdded

                                         javax.faces.component.UIComponent root)

check if we already added components to the layout component.
if this is the case then:

• keep them cached and avoid readd
• in development mode: remove the components
• in production mode: keep them cached

TODO: need to figure out whats the best way to recreate the components

Returns:

true if we have to add our components again

encodeChildren

Overrides:

encodeChildren in class javax.faces.render.Renderer

Throws:

java.io.IOException
