public Object convertSelectManyValue(FacesContext context,
                                     UISelectMany uiSelectMany,
                                     String[] newValues)
                              throws ConverterException

Throws:

ConverterException

convertSelectOneValue

public Object convertSelectOneValue(FacesContext context,
                                    UISelectOne uiSelectOne,
                                    String newValue)
                             throws ConverterException

Throws:

ConverterException

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 HtmlBasicRenderer

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

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 HtmlBasicRenderer

Parameters:

context - FacesContext for the response we are creating

component - UIComponent to be rendered

Throws:

IOException - if an input/output error occurs while rendering

getConvertedValue

public Object getConvertedValue(FacesContext context,
                                UIComponent component,
                                Object submittedValue)
                         throws ConverterException

Description copied from class: Renderer

Attempt to convert previously stored state information into an object of the type required for this component (optionally using the registered Converter for this component, if there is one). If conversion is successful, the new value should be returned from this method; if not, a ConverterException should be thrown.

Overrides:

getConvertedValue in class HtmlBasicInputRenderer

Parameters:

context - FacesContext for the request we are processing

component - UIComponent to be decoded.

submittedValue - a value stored on the component during decode.

Returns:

the converted value

Throws:

ConverterException - if the submitted value cannot be converted successfully.
