com.sun.rave.web.ui.component.util.descriptors .LayoutWhile

LayoutWhile
public class LayoutWhile extends LayoutIf implements LayoutElement(Code)
	This class defines a LayoutWhile LayoutElement . The LayoutWhile provides the functionality necessary to iteratively display a portion of the layout tree. The condition is a boolean equation and may use "$...{...}" type expressions to substitute values. See Also: com.sun.rave.web.ui.util.VariableResolver See Also: com.sun.rave.web.ui.util.PermissionChecker author: Ken Paulsen (ken.paulsen@sun.com)

Field Summary
final public static String	AFTER_LOOP
final public static String	BEFORE_LOOP

Constructor Summary
public	LayoutWhile(LayoutElement parent, String condition)

Method Summary
public void	encode(FacesContext context, UIComponent component) This implementation overrides the parent `encode` method.
protected boolean	encodeThis(FacesContext context, UIComponent component) This method always returns true.
protected boolean	shouldContinue(UIComponent component) This method returns true if the condition of this LayoutWhile is met, false otherwise.

Field Detail

AFTER_LOOP
final public static String AFTER_LOOP(Code)
	This is the event "type" for com.sun.rave.web.ui.component.util.event.Handler elements to be invoked after this LayoutWhile is processed (outside loop).

BEFORE_LOOP
final public static String BEFORE_LOOP(Code)
	This is the event "type" for com.sun.rave.web.ui.component.util.event.Handler elements to be invoked before this LayoutWhile is processed (outside loop).

Constructor Detail

LayoutWhile
public LayoutWhile(LayoutElement parent, String condition)(Code)
	Constructor

Method Detail

encode
public void encode(FacesContext context, UIComponent component) throws IOException(Code)
	This implementation overrides the parent `encode` method. It does this to cause the encode process to loop while LayoutWhile.shouldContinue(UIComponent) returns true. Currently there is no infinite loop checking, so be careful. Parameters: context - The FacesContext Parameters: component - The UIComponent

encodeThis
protected boolean encodeThis(FacesContext context, UIComponent component)(Code)
	This method always returns true. The condition is checked in LayoutWhile.shouldContinue(UIComponent) instead of here because the LayoutWhile.encode(FacesContext,UIComponent) method evaluates the condition and calls the super. Performing the check here would cause the condition to be evaluated twice. Parameters: context - The FacesContext Parameters: component - The UIComponent true

shouldContinue
protected boolean shouldContinue(UIComponent component)(Code)
	This method returns true if the condition of this LayoutWhile is met, false otherwise. This provides the functionality for iteratively displaying a portion of the layout tree. Parameters: component - The UIComponent true if children are to be rendered, false otherwise.
