Class Resource

dw.web.Resource
Library class which provides methods for retrieving messages from properties resource bundles which contain locale-specific strings. When your program needs a locale-specific String, it loads it from the resource bundle that is appropriate for the user's current locale. In this way, the program code is largely independent of the user's locale.

In Commerce Cloud Digital, resources are associated with the templates of a cartridge. These bundles consist of properties files with a common name defined in the template/resources directory of a site cartridge. For example:

  • templates/resources/message.properties
  • templates/resources/message_en.properties
  • templates/resources/message_en_US.properties
  • templates/resources/message_de_DE.properties
Resource bundle lookup generally follows the same rules as the Java ResourceBundle class, where the locale used for lookup is based on the current request. See method javadoc for additional details.

Properties resource files are assumed to use the ISO 8859-1 character encoding; that is each byte is one Latin1 character. Characters not in Latin1, and certain special characters, are represented in keys and elements using Unicode escapes.

Constructor Summary
This class does not have a constructor, so you cannot create it directly.
Method Summary
static msg(key : String) : String
Returns the message from the default properties resource bundle (base name "message") corresponding to the specified key and the request locale.
static msg(key : String, defaultMessage : String) : String
Returns the message from the default properties resource bundle (base name "message") corresponding to the specified key and the request locale.
static msg(key : String, bundleName : String, defaultMessage : String) : String
Returns the message from the specified properties resource bundle.
static msgf(key : String, bundleName : String, defaultMessage : String, args : Object...) : String
Returns the message from the specified properties resource bundle, with the provided arguments substituted for the message argument placeholders (specified using the Java MessageFormat approach).

Method Detail
msg
static msg(key : String) : String
Returns the message from the default properties resource bundle (base name "message") corresponding to the specified key and the request locale. This method is equivalent to msg(String, null).
Parameters:
key - resource bundle message key
Returns:
the resource bundle message or the key itself if no message is defined.

msg
static msg(key : String, defaultMessage : String) : String
Returns the message from the default properties resource bundle (base name "message") corresponding to the specified key and the request locale. If no message for the key is found, returns the default message if it is not null, otherwise returns the key itself. This method is equivalent to msg(key, null, defaultMessage).
Parameters:
key - resource bundle message key
defaultMessage - default message to return if no message corresponding to the key is found
Returns:
the resource bundle message or default message

msg
static msg(key : String, bundleName : String, defaultMessage : String) : String
Returns the message from the specified properties resource bundle. The resource bundle is located by iterating the site cartridges and looking for a bundle with the specified name in the cartridge template/resources directory. If it finds a bundle, it tries to return a message from the bundle using standard Java ResourceBundle logic. If a message is found in that cartridge's bundle, it is returned, otherwise, the next cartridge is examined. The method throws an exception if the key is null.
Parameters:
key - resource bundle message key
bundleName - base bundle name, if null, default bundle name, "message", is used
defaultMessage - default message to return if no message corresponding to the key is found and defaultMessage is not null
Returns:
the resource bundle message or default message

msgf
static msgf(key : String, bundleName : String, defaultMessage : String, args : Object...) : String
Returns the message from the specified properties resource bundle, with the provided arguments substituted for the message argument placeholders (specified using the Java MessageFormat approach). If null is passed for the varargs argument, this method is equivalent to msg(key, bundleName, defaultMessage).
Parameters:
key - resource bundle message key
bundleName - base bundle name, if null, default bundle name, "message", is used
defaultMessage - default message to return if no message corresponding to the key is found and defaultMessage is not null
args - optional list of arguments or a collection, which are included into the result string
Returns:
the resource bundle message or default message
