Class ByteConverter

java.lang.Object
  javax.faces.convert.ByteConverter

All Implemented Interfaces:: Converter

public class ByteConverter
extends Object
implements Converter
extends Object
implements Converter

Converter implementation for java.lang.Byte (and byte primitive) values.

Field Summary

static String BYTE_ID
          The message identifier of the FacesMessage to be created if the conversion to Byte 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 Byte value to String fails.

Constructor Summary

ByteConverter()


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.

Field Detail

CONVERTER_ID

public static final String CONVERTER_ID

The standard converter id for this converter.

See Also:: Constant Field Values

BYTE_ID

public static final String BYTE_ID

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

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

See Also:: 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 Byte 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)
