of

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 of(int) method.

Parameters:

c - The character in question

Returns:

The UnicodeBlock instance representing the Unicode block of which this character is a member, ornull if the character is not a member of any Unicode block

of

public static Character.UnicodeBlock of(int codePoint)

Returns the object representing the Unicode block containing the given character (Unicode code point), ornull if the character is not a member of a defined block.

Parameters:

codePoint - the character (Unicode code point) in question.

Returns:

The UnicodeBlock instance representing the Unicode block of which this character is a member, ornull if the character is not a member of any Unicode block

Throws:

[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang") - if the specifiedcodePoint is an invalid Unicode code point.

Since:

1.5

See Also:

Character.isValidCodePoint(int)

forName

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-.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 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:

blockName - A UnicodeBlock name.

Returns:

The UnicodeBlock instance identified by blockName

Throws:

[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang") - if blockName is an invalid name

[NullPointerException](../../java/lang/NullPointerException.html "class in java.lang") - if blockName is null
