Enum Constant Details

i18n

public static final I18nHelper i18n

A helper built on top of ResourceBundle. A ResourceBundle is the most well known mechanism for internationalization (i18n).

messages.properties:

  hello=Hola
 

Basic Usage:

  {{i18n "hello"}}
 

Will result in: Hola

Using a locale:

  {{i18n "hello" locale="es_AR"}}
 

Using a different bundle:

  {{i18n "hello" bundle="myMessages"}}
 

Using a message format:

  hello=Hola {0}!
 

  {{i18n "hello" "Handlebars.java"}}
 

Since:

0.9.0

i18nJs

public static final I18nHelper i18nJs

Translate a ResourceBundle into JavaScript code. The generated code assume you added the I18n

It converts message patterns like: Hi {0} into Hi {{arg0}}. This make possible to the I18n JS library to interpolate variables.

Note: make sure you include I18n in your application. Otherwise, the generated code will fail.

Usage:

  {{i18nJs locale?}}
 

If locale argument is present it will translate that locale to JavaScript. Otherwise, the default locale.

Method Details

values

public static I18nHelper[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static I18nHelper valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

Parameters:

bundle - The default's bundle name. Required.
