Converter

---

public class BooleanConverter
extends Object
implements Converter

Converter implementation for java.lang.Boolean (and boolean primitive) values.

Field Summary
static String	BOOLEAN_ID           The message identifier of the FacesMessage to be created if the conversion to Boolean fails.
static String	CONVERTER_ID           The standard converter id for this converter.
static String	STRING_ID           The message identifier of the FacesMessage to be created if the conversion of the Boolean value to String fails.

 

Constructor Summary
BooleanConverter()

 

Method Summary
Object	getAsObject(FacesContext context, UIComponent component, 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.
String	getAsString(FacesContext context, UIComponent component, Object value)           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.

BOOLEAN_ID

public static final 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 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 Object getAsObject(FacesContext context,
                          UIComponent component,
                          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

NullPointerException - if context or component is null

---

getAsString

public String getAsString(FacesContext context,
                          UIComponent component,
                          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
