Method Detail

getValueToRender

public static String getValueToRender(javax.faces.context.FacesContext context,
                      javax.faces.component.UIComponent component)

getValueToRender

public static String getValueToRender(javax.faces.context.FacesContext context,
                      javax.faces.component.UIComponent component,
                      Object value)

Algorithm works as follows; - If it's an input component, submitted value is checked first since it'd be the value to be used in case validation errors terminates jsf lifecycle - Finally the value of the component is retrieved from backing bean and if there's a converter, converted value is returned

Parameters:

context - FacesContext instance

component - UIComponent instance whose value will be returned

value - The value of UIComponent if already evaluated outside. E.g. in the renderer.

Returns:

End text

getConverter

public static javax.faces.convert.Converter getConverter(javax.faces.context.FacesContext context,
                                         javax.faces.component.UIComponent component)

Finds appropriate converter for a given value holder

Parameters:

context - FacesContext instance

component - ValueHolder instance to look converter for

Returns:

Converter
