Interface NLS

All Known Implementing Classes:

BinaryNLS

public interface NLS

NLS provides support for manipulating messages and languages.

Each instance of a NLS manages a set of messages, and each message is defined by a unique ID (int value).

Each language is defined by a locale string. By convention, a locale represents a specific geographical, political, or cultural region. It is often represented using the concatenation of a language code and a country code:

• The language code is the lower-case, two-letter codes as defined by ISO-639.
• The country code is the upper-case, two-letter codes as defined by ISO-3166.
