    • 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(jakarta.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
      Parameters:
      context - the Faces context.
      Returns:
      the saved state.

    • 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(jakarta.faces.context.FacesContext, java.lang.Object) method on all those instances as well.

      If the state argument is null, take no action and return.

      Specified by:
      restoreState in interface StateHolder
      Parameters:
      context - the Faces context.
      state - the state.

    • isTransient

      public boolean isTransient()
      Description copied from interface: StateHolder

      If true, the Object implementing this interface must not participate in state saving or restoring.

      Specified by:
      isTransient in interface StateHolder
      Returns:
      true if transient, false otherwise.

    • setTransient

      public void setTransient​(boolean newTransientValue)
      Description copied from interface: StateHolder

      Denotes whether or not the Object implementing this interface must or must not participate in state saving or restoring.

      Specified by:
      setTransient in interface StateHolder
      Parameters:
      newTransientValue - boolean pass true if this Object will not participate in state saving or restoring, otherwise pass false.

    • getWrapped

      public ValueBinding getWrapped()
