Methods

 

encodeBegin

public void encodeBegin(FacesContext context,
                        UIComponent component) throws IOException

Renders the beginning of the component.

Doesn't need to do anything; all processing is done in encodeEnd.

• Parameters

  • context - FacesContext for the request we are processing

  • component - UIComponent to be rendered

• Throws

  • IOException if an input/output error occurs while rendering

• Overrides

  • encodeBegin in class Renderer

• See Also

  • encodeBegin

 

encodeChildren

public void encodeChildren(FacesContext context,
                           UIComponent component) 

Renders component's children.

Doesn't need to do anything, all processing is done in encodeEnd.

• Parameters

  • context - FacesContext for the request we are processing

  • component - UIComponent to be rendered

• Throws

  • IOException if an input/output error occurs while rendering

• Overrides

  • encodeChildren in class Renderer

  • encodeBegin

 

encodeEnd

public void encodeEnd(FacesContext context,
                      UIComponent component) throws IOException

Renders the ending of the component.

Renders the entire component.

Creates an IMG tag.

• If a regular image file is used for the image, src attribute is set to point to that file.
• If the component is bound to a data source, src attribute is set to use JsfResourceServlet mapping. File name is constructed from "/jsfresource/" prefix and the actual file name in the data source (if file name is stored in the data source. If not, a temporary file name is generated).

• Parameters

  • context - FacesContext for the request we are processing

  • component - UIComponent to be rendered

• Throws

  • IOException if an input/output error occurs while rendering

• Overrides

  • encodeEnd in class HtmlBasicRenderer
