Class LongConverter

java.lang.Object
  javax.faces.convert.LongConverter

All Implemented Interfaces:

Converter

public class LongConverter
extends java.lang.Object
implements Converter

Converter implementation for java.lang.Long (and long primitive) values.

Field Summary

static java.lang.String	CONVERTER_ID The standard converter id for this converter.
static java.lang.String	LONG_ID The message identifier of the FacesMessage to be created if the conversion to Long fails.
static java.lang.String	STRING_ID The message identifier of the FacesMessage to be created if the conversion of the Long value to String fails.

Constructor Summary

LongConverter()

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) 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.

LONG_ID

public static final java.lang.String LONG_ID

The message identifier of the FacesMessage to be created if the conversion to Long 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.

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 Long 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
