Class CurrencyTagConverter

java.lang.Object

atg.droplet.CurrencyTagConverter

All Implemented Interfaces:

TagConverter, java.io.Serializable

Direct Known Subclasses:

CurrencyConversionTagConverter, EuroTagConverter

public class CurrencyTagConverter
extends java.lang.Object
implements TagConverter

A tag converter which is used to parse and format currency amounts.

An example of this is as follows:

<valueof param="priceInfo.amount" currency>no price</valueof>

You can also specify a locale the currency should be rendered with:

<valueof param="priceInfo.amount" currency locale="en_US">no price</valueof>

If no locale is specified then the converter first looks for a request parameter named locale. This parameter can either be a java.util.Locale object or a String which names a locale. If this cannot be found then we fetch the locale from the RequestLocale.

Method Detail

setDefaultLocale

public void setDefaultLocale(java.util.Locale pDefaultLocale)

Sets property DefaultLocale

getDefaultLocale

public java.util.Locale getDefaultLocale()

Returns property DefaultLocale. If the property value is null, then JVM's default locale is returned.

getName

public java.lang.String getName()

Returns the unique name for the TagConverter. This name can be used by the TagConverterManager to get a handle to this converter. When you specify the use of a TagConverter using the converter attribute in a tag, you use this name to refer to the TagConverter. TagConverter names are case insensitive (as is the convention in HTML).

Specified by:

getName in interface TagConverter

getTagAttributeDescriptors

public TagAttributeDescriptor[] getTagAttributeDescriptors()

Returns the list of TagAttributeDescriptors which are used by this converter.

Specified by:

getTagAttributeDescriptors in interface TagConverter

convertStringToObject

public java.lang.Object convertStringToObject(DynamoHttpServletRequest pRequest,
                                     java.lang.String pValue,
                                     java.util.Properties pAttributes)
                                       throws TagConversionException

Converts the supplied String value to an Object value. This operation is performed if a converter is used with an input tag during the form submission process or if a converter attributes are specified in the param tag when defining a new parameter.

Returns:

the converted object value.
