extends Static
```
Static methods working on GeoAPI types and CodeList values. This class provides:
- Methods for fetching the ISO name or description of a code list:
  - getStandardName(Class) for ISO name
  - getListName(CodeList) for ISO name
  - getDescription(Class) for a description
- Methods for fetching the ISO name or description of a code value:
  - getCodeName(CodeList) for ISO name,
  - getCodeTitle(CodeList) for a label or title
  - getDescription(CodeList) for a more verbose description
- Methods for fetching an instance from a name (converse of above get methods):
  - forCodeName(Class, String, boolean)
  - forEnumName(Class, String)
Substituting a free text by a code list
The ISO standard allows to substitute some character strings in the "free text" domain by a CodeList value.
Example: in the following XML fragment, the <mac:type> value is normally a <gco:CharacterString> but has been replaced by a SensorType code below:
```
<mac:MI_Instrument>
  <mac:type>
    <gmi:MI_SensorTypeCode
        codeList="http://standards.iso.org/…snip…/codelists.xml#CI_SensorTypeCode"
        codeListValue="RADIOMETER">Radiometer</gmi:MI_SensorTypeCode>
  </mac:type>
</mac:MI_Instrument>
```
Such substitution can be done with:
- getCodeTitle(CodeList) for getting the InternationalString instance to store in a metadata property.
- forCodeTitle(CharSequence) for retrieving the CodeList previously stored as an InternationalString.

  - getStandardName
```
public static String getStandardName(Class<?> type)
```
    Returns the ISO name for the given class, or null if none. This method can be used for GeoAPI interfaces or CodeList.
    Examples:
    
    getStandardName(Citation.class) (an interface) returns "CI_Citation".
    
    getStandardName(AxisDirection.class) (a code list) returns "CS_AxisDirection".
    
    This method looks for the UML annotation on the given type. It does not search for parent classes or interfaces if the given type is not directly annotated (i.e. @UML annotations are not inherited). If no annotation is found, then this method does not fallback on the Java name since, as the name implies, this method is about standard names.
    Parameters:
    
    type - the GeoAPI interface or code list from which to get the ISO name, or null.
    
    Returns:
    
    the ISO name for the given type, or null if none or if the given type is null.
    
    See Also:
    
    forStandardName(String)
  - getListName
```
public static String getListName(CodeList<?> code)
```
    Returns the ISO classname (if available) or the Java classname (as a fallback) of the given enumeration or code list value. This method uses the UML annotation if it exists, or fallback on the simple class name otherwise.
    Examples:
    
    getListName(ParameterDirection.IN_OUT) returns "SV_ParameterDirection".
    
    getListName(AxisDirection.NORTH) returns "CS_AxisDirection".
    
    getListName(TopicCategory.INLAND_WATERS) returns "MD_TopicCategoryCode".
    
    getListName(ImagingCondition.BLURRED_IMAGE) returns "MD_ImagingConditionCode".
    Parameters:
    
    code - the code for which to get the class name, or null.
    
    Returns:
    
    the ISO (preferred) or Java (fallback) class name, or null if the given code is null.
  - getCodeName
```
public static String getCodeName(CodeList<?> code)
```
    Returns the ISO name (if available) or the Java name (as a fallback) of the given enumeration or code list value. If the value has no UML identifier, then the programmatic name is used as a fallback.
    Examples:
    
    getCodeName(ParameterDirection.IN_OUT) returns "in/out".
    
    getCodeName(AxisDirection.NORTH) returns "north".
    
    getCodeName(TopicCategory.INLAND_WATERS) returns "inlandWaters".
    
    getCodeName(ImagingCondition.BLURRED_IMAGE) returns "blurredImage".
    Parameters:
    
    code - the code for which to get the name, or null.
    
    Returns:
    
    the UML identifiers or programmatic name for the given code, or null if the given code is null.
    
    See Also:
    
    getCodeLabel(CodeList), getCodeTitle(CodeList), getDescription(CodeList), forCodeName(Class, String, boolean)
  - getCodeLabel
```
public static String getCodeLabel(CodeList<?> code)
```
    Returns a unlocalized title for the given enumeration or code list value. This method builds a title using heuristics rules, which should give reasonable results without the need of resource bundles. For better results, consider using getCodeTitle(CodeList) instead.
    The current heuristic implementation iterates over all code names, selects the longest one excluding the field name if possible, then makes a sentence from that name.
    
    Examples:
    
    getCodeLabel(AxisDirection.NORTH) returns "North".
    
    getCodeLabel(TopicCategory.INLAND_WATERS) returns "Inland waters".
    
    getCodeLabel(ImagingCondition.BLURRED_IMAGE) returns "Blurred image".
    Parameters:
    
    code - the code from which to get a title, or null.
    
    Returns:
    
    a unlocalized title for the given code, or null if the given code is null.

    getCodeName(CodeList), getCodeTitle(CodeList), getDescription(CodeList)
  - getCodeTitle
```
public static InternationalString getCodeTitle(CodeList<?> code)
```
    Returns the title of the given enumeration or code list value. Title are usually much shorter than descriptions. English titles are often the same than the code labels.
    The code or enumeration value given in argument to this method can be retrieved from the returned title with the forCodeTitle(CharSequence) method. See Substituting a free text by a code list in this class javadoc for more information.
    
    Parameters:
    
    code - the code for which to get the title, or null.
    
    Returns:
    
    the title, or null if the given code is null.
    
    See Also:
    
    getDescription(CodeList), forCodeTitle(CharSequence)
  - getDescription
```
public static InternationalString getDescription(CodeList<?> code)
```
    Returns the description of the given enumeration or code list value, or null if none. For a description of the code list as a whole instead than a particular code, see getDescription(Class).
    
    Parameters:
    
    code - the code for which to get the localized description, or null.
    
    Returns:
    
    the description, or null if none or if the given code is null.

    getCodeTitle(CodeList), getDescription(Class)
  - getDescription
```
public static InternationalString getDescription(Class<?> type)
```
    Returns a description for the given class, or null if none. This method can be used for GeoAPI interfaces or CodeList.
    
    Parameters:
    
    type - the GeoAPI interface or code list from which to get the description, or null.
    
    Returns:
    
    the description, or null if none or if the given type is null.
    
    See Also:
    
    getDescription(CodeList)
  - getDescription
```
public static InternationalString getDescription(Class<?> type,
                                                 String property)
```
    Returns a description for the given property, or null if none. The given type shall be a GeoAPI interface, and the given property shall be a UML identifier. If any of the input argument is null, then this method returns null.
    
    Parameters:
    
    type - the GeoAPI interface from which to get the description of a property, or null.
    
    property - the ISO name of the property for which to get the description, or null.
    
    Returns:
    
    the description, or null if none or if the given type or property name is null.
  - getCodeValues
```
public static <T extends CodeList<?>> T[] getCodeValues(Class<T> codeType)
```
    Returns all known values for the given type of code list. Note that the size of the returned array may growth between different invocations of this method, since users can add their own codes to an existing list.
    
    Type Parameters:
    
    T - the compile-time type given as the codeType parameter.
    
    Parameters:
    
    codeType - the type of code list.
    
    Returns:
    
    the list of values for the given code list, or an empty array if none.
    
    See Also:
    
    Class.getEnumConstants()
  - forStandardName
```
public static Class<?> forStandardName(String identifier)
```
    Returns the Java type (usually a GeoAPI interface) for the given ISO name, or null if none. The identifier argument shall be the value documented in the UML.identifier() annotation on the Java type.
    Examples:
    
    forStandardName("CI_Citation") returns Citation.class
    
    forStandardName("CS_AxisDirection") returns AxisDirection.class
    
    The package prefix (e.g. "CI_" in "CI_Citation") can be omitted. The flexibility is provided for allowing transition to newer ISO standards, which are dropping the package prefixes. For example "CS_AxisDirection" in ISO 19111:2007 has been renamed "AxisDirection" in ISO 19111:2018.
    Only identifiers for the stable part of GeoAPI or for some Apache SIS classes are recognized. This method does not handle the identifiers for interfaces in the geoapi-pending module.
    
    Future evolution: when a new ISO type does not yet have a corresponding GeoAPI interface, this method may temporarily return an Apache SIS class instead, until a future version can use the interface. For example forStandardName("CI_Individual") returns DefaultIndividual.class in Apache SIS versions that depend on GeoAPI 3.0, but the return type may be changed to Individual.class when Apache SIS will be upgraded to GeoAPI 3.1.
    Parameters:
    
    identifier - the ISO UML identifier, or null.
    
    Returns:
    
    the GeoAPI interface, or null if the given identifier is null or unknown.
  - forEnumName
```
public static <T extends Enum<T>> T forEnumName(Class<T> enumType,
                                                String name)
```
    Returns the enumeration value of the given type that matches the given name, or null if none. This method is similar to the standard Enum.valueOf(…) method, except that this method is more tolerant on string comparisons:
    
    Name comparisons are case-insensitive.
    
    Only letter and digit characters are compared. Spaces and punctuation characters like '_' and '-' are ignored.
    
    If there is no match, this method returns null — it does not thrown an exception, unless the given class is not an enumeration.
    Type Parameters:
    
    T - the compile-time type given as the enumType parameter.
    
    Parameters:
    
    enumType - the type of enumeration.
    
    name - the name of the enumeration value to obtain, or null.
    
    Returns:
    
    a value matching the given name, or null if the name is null or if no matching enumeration is found.

```
public static <T extends CodeList<T>> T forCodeName(Class<T> codeType,
                                                    String name,
                                                    boolean canCreate)
```
    Returns the code of the given type that matches the given name, or optionally returns a new one if none match the name. This method performs the same work than the GeoAPI CodeList.valueOf(…) method, except that this method is more tolerant on string comparisons when looking for an existing code:
    
    Name comparisons are case-insensitive.
    
    Only letter and digit characters are compared. Spaces and punctuation characters like '_' and '-' are ignored.
    
    If no match is found, then a new code is created only if the canCreate argument is true. Otherwise this method returns null.
    Type Parameters:
    
    T - the compile-time type given as the codeType parameter.
    
    Parameters:
    
    codeType - the type of code list.
    
    name - the name of the code to obtain, or null.
    
    canCreate - true if this method is allowed to create new code.
    
    Returns:
    
    a code matching the given name, or null if the name is null or if no matching code is found and canCreate is false.

  - forCodeTitle
```
public static CodeList<?> forCodeTitle(CharSequence title)
```
    Returns the code list or enumeration value for the given title, or null if none. The current implementation performs the following choice:
    
    If the given title is a value returned by a previous call to getCodeTitle(CodeList), returns the code or enumeration value used for creating that title.
    
    Otherwise returns null.
    Parameters:
    
    title - the title for which to get a code or enumeration value, or null.
    
    Returns:
    
    the code or enumeration value associated with the given title, or null.

  - toInternationalString
```
public static InternationalString toInternationalString(Map<String,?> properties,
                                                        String prefix)
                                                 throws IllegalArgumentException
```
    Returns an international string for the values in the given properties map, or null if none. This method is used when a property in a Map may have many localized variants. For example the given map may contains a "remarks" property defined by values associated to the "remarks_en" and "remarks_fr" keys, for English and French locales respectively.
    If the given map is null, then this method returns null. Otherwise this method iterates over the entries having a key that starts with the specified prefix, followed by the '_' character. For each such key:
    
    If the key is exactly equals to prefix, selects Locale.ROOT.
    
    Otherwise the characters after '_' are parsed as an ISO language and country code by the Locales.parse(String, int) method. Note that 3-letters codes are replaced by their 2-letters counterparts on a best effort basis.
    
    The value for the decoded locale is added in the international string to be returned.
    Parameters:
    
    properties - the map from which to get the string values for an international string, or null.
    
    prefix - the prefix of keys to use for creating the international string.
    
    Returns:
    
    the international string, or null if the given map is null or does not contain values associated to keys starting with the given prefix.
    
    Throws:
    
    IllegalArgumentException - if a key starts by the given prefix and:
    
    The key suffix is an illegal Locale code,
    
    or the value associated to that key is a not a CharSequence.

  - toInternationalString
```
public static InternationalString toInternationalString(CharSequence string)
```
    Returns the given characters sequence as an international string. If the given sequence is null or an instance of InternationalString, then this method returns it unchanged. Otherwise, this method copies the InternationalString.toString() value in a new SimpleInternationalString instance and returns it.
    
    Parameters:
    
    string - the characters sequence to convert, or null.
    
    Returns:
    
    the given sequence as an international string, or null if the given sequence was null.
    
    See Also:
    
    DefaultNameFactory.createInternationalString(Map)
  - toInternationalStrings
```
public static InternationalString[] toInternationalStrings(CharSequence... strings)
```
    Returns the given array of CharSequences as an array of InternationalStrings. If the given array is null or an instance of InternationalString[], then this method returns it unchanged. Otherwise a new array of type InternationalString[] is created and every elements from the given array is copied or casted in the new array.
    If a defensive copy of the strings array is wanted, then the caller needs to check if the returned array is the same instance than the one given in argument to this method.
    
    Parameters:
    
    strings - the characters sequences to convert, or null.
    
    Returns:
    
    the given array as an array of type InternationalString[], or null if the given array was null.
  - toString
```
public static String toString(InternationalString i18n,
                              Locale locale)
```
    Returns the given international string in the given locale, or null if the given string is null. If the given locale is null, then the i18n default locale is used.
    
    Parameters:
    
    i18n - the international string to get as a localized string, or null if none.
    
    locale - the desired locale, or null for the i18n default locale.
    
    Returns:
    
    the localized string, or null if i18n is null.
