Class: java.lang.Character.UnicodeBlock

  • public static final class Character.UnicodeBlock
  • extends Character.Subset
A family of character subsets representing the character blocks in the Unicode specification. Character blocks generally define characters used for a specific script or purpose. A character is contained by at most one Unicode block.

Methods

  • forNametop

    public static final Character.UnicodeBlock forName(String blockName)
    Returns the UnicodeBlock with the given name. Block names are determined by The Unicode Standard. The file Blocks-<version>.txt defines blocks for a particular version of the standard. The Character class specifies the version of the standard that it supports.

    This method accepts block names in the following forms:

    1. Canonical block names as defined by the Unicode Standard. For example, the standard defines a "Basic Latin" block. Therefore, this method accepts "Basic Latin" as a valid block name. The documentation of each UnicodeBlock provides the canonical name.
    2. Canonical block names with all spaces removed. For example, "BasicLatin" is a valid block name for the "Basic Latin" block.
    3. The text representation of each constant UnicodeBlock identifier. For example, this method will return the Character$UnicodeBlock.BASIC_LATIN block if provided with the "BASIC_LATIN" name. This form replaces all spaces and hyphens in the canonical name with underscores.
    Finally, character case is ignored for all of the valid block name forms. For example, "BASIC_LATIN" and "basic_latin" are both valid block names. The en_US locale's case mapping rules are used to provide case-insensitive string comparisons for block name validation.

    If the Unicode Standard changes block names, both the previous and current names will be accepted.

    Parameters:
    @param blockName A UnicodeBlock name.
    Return:
    @return The UnicodeBlock instance identified by blockName
    Exceptions:
    @throws IllegalArgumentException if blockName is an invalid name
    @throws NullPointerException if blockName is null

  • oftop

    public static Character.UnicodeBlock of(char c)
    Returns the object representing the Unicode block containing the given character, or null if the character is not a member of a defined block.

    Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the Character$UnicodeBlock.of(int) method.

    Parameters:
    @param c The character in question
    Return:
    @return The UnicodeBlock instance representing the Unicode block of which this character is a member, or null if the character is not a member of any Unicode block

  • oftop

    public static Character.UnicodeBlock of(int codePoint)
    Returns the object representing the Unicode block containing the given character (Unicode code point), or null if the character is not a member of a defined block.
    Parameters:
    @param codePoint the character (Unicode code point) in question.
    Return:
    @return The UnicodeBlock instance representing the Unicode block of which this character is a member, or null if the character is not a member of any Unicode block
    Exceptions:
    @exception IllegalArgumentException if the specified codePoint is an invalid Unicode code point.
