  - compareTo
```
int compareTo(GwtLocale o)
```
    The default comparison is a lexical ordering.
    
    Specified by:
    
    compareTo in interface Comparable<GwtLocale>
  - getAliases
```
List<GwtLocale> getAliases()
```
    Returns the list of aliases for this locale. The canonical form of the current locale is always first on the list. Language/region codes have changed over time, so some systems continue to use the older codes. Aliases allow GWT to use the official Unicode CLDR locales while still interoperating with such systems.
    
    Returns:
    
    alias list
  - getAsString
```
String getAsString()
```
    Returns the locale as a fixed-format string suitable for use in searching for localized resources. The format is language_Script_REGION_VARIANT, where language is a 2-8 letter code (possibly with 3-letter extensions), script is a 4-letter code with an initial capital letter, region is a 2-character country code or a 3-digit region code, and variant is a 5-8 character (may be 4 if the first character is numeric) code. If a component is missing, its preceding _ is also omitted. If this is the default locale, the empty string will be returned.
    
    Returns:
    
    String representing locale
  - getCanonicalForm
```
GwtLocale getCanonicalForm()
```
    Returns this locale in canonical form.
    - Deprecated language/region tags are replaced with official versions
    - Default scripts are removed (including region-specific defaults for Chinese)
    - no/nb/nn are normalized
    - Default region for zh_Hans and zh_Hant if none specified
    Returns:
    
    GwtLocale instance
  - getCompleteSearchList
```
List<GwtLocale> getCompleteSearchList()
```
    Returns the complete list of locales to search for the current locale. This list will always start with the canonical form of this locale, and end with "default", and include all appropriate aliases along the way.
    
    Returns:
    
    search list
  - getInheritanceChain
```
List<GwtLocale> getInheritanceChain()
```
    Returns a list of locales to search for, in order of preference. The current locale is always first on the list. Aliases are not included in the list -- use getAliases() to expand those.
    
    Returns:
    
    inheritance list
  - getLanguage
```
String getLanguage()
```
    Returns the language portion of the locale, or null if none.
  - getLanguageNotNull
```
String getLanguageNotNull()
```
    Returns the language portion of the locale, or the empty string if none.
  - getRegion
```
String getRegion()
```
    Returns the region portion of the locale, or null if none.
  - getRegionNotNull
```
String getRegionNotNull()
```
    Returns the region portion of the locale, or the empty string if none.
  - getScript
```
String getScript()
```
    Returns the script portion of the locale, or null if none.
  - getScriptNotNull
```
String getScriptNotNull()
```
    Returns the script portion of the locale, or the empty string if none.
  - getVariant
```
String getVariant()
```
    Returns the variant portion of the locale, or null if none.
  - getVariantNotNull
```
String getVariantNotNull()
```
    Returns the variant portion of the locale, or the empty string if none.
  - inheritsFrom
```
boolean inheritsFrom(GwtLocale parent)
```
    Returns true if this locale inherits from the specified locale. Note that locale.inheritsFrom(locale) is false -- if you want that to be true, you should just use locale.getInheritanceChain().contains(x).
    
    Parameters:
    
    parent - locale to test against
    
    Returns:
    
    true if parent is an ancestor of this locale
  - isDefault
```
boolean isDefault()
```
    Returns true if this is the default or root locale.
  - toString
```
String toString()
```
    Returns a human readable string -- "default" or the same as getAsString().
    
    Overrides:
    
    toString in class Object
  - usesSameScript
```
boolean usesSameScript(GwtLocale other)
```
    Checks if this locale uses the same script as another locale.
    
    Parameters:
    
    other -
    
    Returns:
    
    true if the scripts are the same
