HtmlPanelGroup (Java EE 5 SDK) - Java Platform, Enterprise Edition v5.0 API Specifications

Java EE 5 SDK

javax.faces.component.html
Class HtmlPanelGroup

java.lang.Object
  extended by javax.faces.component.UIComponent
      extended by javax.faces.component.UIComponentBase
          extended by javax.faces.component.UIPanel
              extended by javax.faces.component.html.HtmlPanelGroup
All Implemented Interfaces:
StateHolder

public class HtmlPanelGroup
extends UIPanel

Causes all child components of this component to be rendered. This is useful in scenarios where a parent component is expecting a single component to be present, but the application wishes to render more than one.

By default, the rendererType property must be set to "javax.faces.Group". This value can be changed by calling the setRendererType() method.

Field Detail

COMPONENT_TYPE

public static final String COMPONENT_TYPE

The standard component type for this component.

Constant Field Values
Constructor Detail

HtmlPanelGroup

public HtmlPanelGroup()
Method Detail

getLayout

public String getLayout()

Return the value of the layout property.

Contents: The type of layout markup to use when rendering this group. If the value is "block" the renderer must produce an HTML "div" element. Otherwise HTML "span" element must be produced.


setLayout

public void setLayout(String layout)

Set the value of the layout property.


getStyle

public String getStyle()

Return the value of the style property.

Contents: CSS style(s) to be applied when this component is rendered.


setStyle

public void setStyle(String style)

Set the value of the style property.


getStyleClass

public String getStyleClass()

Return the value of the styleClass property.

Contents: Space-separated list of CSS style class(es) to be applied when this element is rendered. This value must be passed through as the "class" property on generated markup.


setStyleClass

public void setStyleClass(String styleClass)

Set the value of the styleClass property.


saveState

public Object saveState(FacesContext _context)
Description copied from interface: StateHolder

Gets the state of the instance as a Serializable Object.

If the class that implements this interface has references to instances that implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.saveState(javax.faces.context.FacesContext) method on all those instances as well. This method must not save the state of children and facets. That is done via the StateManager

This method must not alter the state of the implementing object. In other words, after executing this code:

 Object state = component.saveState(facesContext);
 

component should be the same as before executing it.

The return from this method must be Serializable

Specified by:
saveState in interface StateHolder
Overrides:
saveState in class UIComponentBase

restoreState

public void restoreState(FacesContext _context,
                         Object _state)
Description copied from interface: StateHolder

Perform any processing required to restore the state from the entries in the state Object.

If the class that implements this interface has references to instances that also implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object) method on all those instances as well.

Specified by:
restoreState in interface StateHolder
Overrides:
restoreState in class UIComponentBase
