    • decode

      public void decode​(FacesContext context, UIComponent component)
      Description copied from class: Renderer

      Decode any new state of the specified UIComponent from the request contained in the specified FacesContext, and store that state on the UIComponent.

      During decoding, events may be enqueued for later processing (by event listeners that have registered an interest), by calling queueEvent() on the associated UIComponent.

      Overrides:
      decode in class Renderer
      Parameters:
      context - FacesContext for the request we are processing
      component - UIComponent to be decoded.
    • encodeBegin

      public void encodeBegin​(FacesContext context, UIComponent component) throws IOException
      Description copied from class: Renderer

      Render the beginning specified UIComponent to the output stream or writer associated with the response we are creating. If the conversion attempted in a previous call to getConvertedValue() for this component failed, the state information saved during execution of decode() should be used to reproduce the incorrect input.

      Overrides:
      encodeBegin in class Renderer
      Parameters:
      context - FacesContext for the request we are processing
      component - UIComponent to be rendered
      Throws:
      IOException - if an input/output error occurs while rendering
    • encodeChildren

      public void encodeChildren​(FacesContext context, UIComponent component) throws IOException
      Description copied from class: Renderer

      Render the child components of this UIComponent, following the rules described for encodeBegin() to acquire the appropriate value to be rendered. This method will only be called if the rendersChildren property of this component is true.

      Overrides:
      encodeChildren in class Renderer
      Parameters:
      context - FacesContext for the response we are creating
      component - UIComponent whose children are to be rendered
      Throws:
      IOException - if an input/output error occurs while rendering
    • encodeEnd

      public void encodeEnd​(FacesContext context, UIComponent component) throws IOException
      Description copied from class: Renderer

      Render the ending of the current state of the specified UIComponent, following the rules described for encodeBegin() to acquire the appropriate value to be rendered.

      Overrides:
      encodeEnd in class Renderer
      Parameters:
      context - FacesContext for the response we are creating
      component - UIComponent to be rendered
      Throws:
      IOException - if an input/output error occurs while rendering
