Method Summary
 java.lang.Object getAsObject(FacesContext context, UIComponent component, java.lang.String value)
          Convert the specified string value, which is associated with the specified UIComponent, into a model data object that is appropriate for being stored during the Apply Request Values phase of the request processing lifecycle.
 java.lang.String getAsString(FacesContext context, UIComponent component, java.lang.Object value)

BOOLEAN_ID

public static final java.lang.String BOOLEAN_ID

The message identifier of the FacesMessage to be created if the conversion to Boolean fails. The message format string for this message may optionally include the following placeholders:

  • {0} replaced by the unconverted value.
  • {1} replaced by a String whose value is the label of the input component that produced this message.

Constant Field Values

STRING_ID

public static final java.lang.String STRING_ID

The message identifier of the FacesMessage to be created if the conversion of the Boolean value to String fails. The message format string for this message may optionally include the following placeholders:

  • {0} relaced by the unconverted value.
  • {1} replaced by a String whose value is the label of the input component that produced this message.

Method Detail

getAsObject

public java.lang.Object getAsObject(FacesContext context,
                                    UIComponent component,
                                    java.lang.String value)
Description copied from interface: Converter

Convert the specified string value, which is associated with the specified UIComponent, into a model data object that is appropriate for being stored during the Apply Request Values phase of the request processing lifecycle.

Specified by:
getAsObject in interface Converter
Parameters:
context - FacesContext for the request being processed
component - UIComponent with which this model object value is associated
value - String value to be converted (may be null)
Returns:
null if the value to convert is null, otherwise the result of the conversion
Throws:
ConverterException - if conversion cannot be successfully performed
java.lang.NullPointerException - if context or component is null

getAsString

public java.lang.String getAsString(FacesContext context,
                                    UIComponent component,
                                    java.lang.Object value)
Description copied from interface: Converter

Convert the specified model object value, which is associated with the specified UIComponent, into a String that is suitable for being included in the response generated during the Render Response phase of the request processing lifeycle.

Specified by:
getAsString in interface Converter
Parameters:
context - FacesContext for the request being processed
component - UIComponent with which this model object value is associated
value - Model object value to be converted (may be null)
Returns:
a zero-length String if value is null, otherwise the result of the conversion
Throws:
ConverterException - if conversion cannot be successfully performed
java.lang.NullPointerException - if context or component is null
