Class DefaultI18N

java.lang.Object

org.deeplearning4j.ui.i18n.DefaultI18N

All Implemented Interfaces:

I18N

public class DefaultI18N
extends Object
implements I18N

Default internationalization implementation.
Content for internationalization is implemented using resource files.
For the resource files: they should be specified as follows:
1. In the /dl4j_i18n/ directory in resources
2. Filenames should be "somekey.langcode" - for example, "index.en" or "index.ja"
3. Each key should be unique across all files. Any key can appear in any file; files may be split for convenience

Loading of these UI resources is done as follows:
- On initialization of the DefaultI18N:
- Resource files for the default language are loaded
- If a different language is requested, the content will be loaded on demand (and stored in memory for future use)
Note that if a specified language does not have the specified key, the result from the defaultfallback language (English) will be used instead.
