public static string? GetPropertyValueName (int property, int value, int nameChoice);[<Android.Runtime.Register("getPropertyValueName", "(III)Ljava/lang/String;", "", ApiSince=24)>]
static member GetPropertyValueName : int * int * int -> stringParameters
- property
- Int32
UProperty selector constant. UProperty.INT_START <= property < UProperty.INT_LIMIT or UProperty.BINARY_START <= property < UProperty.BINARY_LIMIT or UProperty.MASK_START < = property < UProperty.MASK_LIMIT. If out of range, null is returned.
- value
- Int32
selector for a value for the given property. In general, valid values range from 0 up to some maximum. There are a few exceptions: (1.) UProperty.BLOCK values begin at the non-zero value BASIC_LATIN.getID(). (2.) UProperty.CANONICAL_COMBINING_CLASS values are not contiguous and range from 0..240. (3.) UProperty.GENERAL_CATEGORY_MASK values are mask values produced by left-shifting 1 by UCharacter.getType(). This allows grouped categories such as [:L:] to be represented. Mask values are non-contiguous.
- nameChoice
- Int32
UProperty.NameChoice selector for which name to get. All values have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by UProperty.NameChoice.LONG + i, where i=1, 2,...
Returns
a name, or null if Unicode explicitly defines no name ("n/a") for a given property/value/nameChoice. If a given nameChoice throws an exception, then all larger values of nameChoice will throw an exception. If null is returned for a given nameChoice, then other nameChoice values may return non-null results.
- Attributes
Remarks
<strong>[icu]</strong> Return the Unicode name for a given property value, as given in the Unicode database file PropertyValueAliases.txt. Most values have more than one name. The nameChoice determines which one is returned.
Note: Some of the names in PropertyValueAliases.txt can only be retrieved using UProperty.GENERAL_CATEGORY_MASK, not UProperty.GENERAL_CATEGORY. These include: "C" / "Other", "L" / "Letter", "LC" / "Cased_Letter", "M" / "Mark", "N" / "Number", "P" / "Punctuation", "S" / "Symbol", and "Z" / "Separator".
