Class IfUIComponent

java.lang.Object
  javax.faces.component.UIComponent
      javax.faces.component.UIComponentBase
          edu.nrao.sss.webapp.faces.component.IfUIComponent

All Implemented Interfaces:

StateHolder

public class IfUIComponent
extends UIComponentBase

The If component isn't really a UI component so much as a flow control component. It only accepts an attribute named "test". If the value of test resolves to true (either the string "true", "1" or a boolean value of true), then the body of the tag is rendered. Otherwise, it is not.
