public class CharUtilities
extends java.lang.Object
This class provides utilities to distinguish various kinds of Unicode
whitespace and to get character widths in a given FontState.
static char | CODE_EOT - Character code used to signal a character boundary in
inline content, such as an inline with borders and padding
or a nested block object.
|
static int | EOT - Character class: Boundary between text runs
|
static int | LINEFEED - Character class: Line feed
|
static char | NBSPACE - non-breaking space
|
static int | NONWHITESPACE - Character class: non-whitespace
|
static char | SOFT_HYPHEN - soft hyphen
|
static char | SPACE - normal space
|
static int | UCWHITESPACE - Character class: Unicode white space
|
static char | WORD_JOINER - word joiner
|
static int | XMLWHITESPACE - Character class: XML whitespace
|
static char | ZERO_WIDTH_NOBREAK_SPACE - zero-width no-break space (= byte order mark)
|
static char | ZERO_WIDTH_SPACE - zero-width space
|
CharUtilities() - Utility class: Constructor prevents instantiating when subclassed.
|
static int | classOf(char c) - Return the appropriate CharClass constant for the type
of the passed character.
|
static boolean | isAdjustableSpace(char c) - Method to determine if the character is an adjustable
space.
|
static boolean | isAlphabetic(char ch) - Indicates whether a character is classified as "Alphabetic" by the Unicode standard.
|
static boolean | isAnySpace(char c) - Determines if the character represents any kind of space.
|
static boolean | isBreakableSpace(char c) - Helper method to determine if the character is a
space with normal behavior.
|
static boolean | isFixedWidthSpace(char c) - Method to determine if the character is a (breakable) fixed-width space.
|
static boolean | isNonBreakableSpace(char c) - Method to determine if the character is a nonbreaking
space.
|
static boolean | isZeroWidthSpace(char c) - Method to determine if the character is a zero-width space.

CODE_EOT
public static final char CODE_EOT
Character code used to signal a character boundary in
inline content, such as an inline with borders and padding
or a nested block object.
EOT
public static final int EOT
Character class: Boundary between text runs
LINEFEED
public static final int LINEFEED
Character class: Line feed
NBSPACE
public static final char NBSPACE
non-breaking space
NONWHITESPACE
public static final int NONWHITESPACE
Character class: non-whitespace
SOFT_HYPHEN
public static final char SOFT_HYPHEN
soft hyphen
SPACE
public static final char SPACE
normal space
UCWHITESPACE
public static final int UCWHITESPACE
Character class: Unicode white space
WORD_JOINER
public static final char WORD_JOINER
word joiner
XMLWHITESPACE
public static final int XMLWHITESPACE
Character class: XML whitespace

CharUtilities
protected CharUtilities()
Utility class: Constructor prevents instantiating when subclassed.
classOf
public static int classOf(char c)
Return the appropriate CharClass constant for the type
of the passed character.
- the determined character class
isAdjustableSpace
public static boolean isAdjustableSpace(char c)
Method to determine if the character is an adjustable
space.
- True if the character is adjustable
isAlphabetic
public static boolean isAlphabetic(char ch)
Indicates whether a character is classified as "Alphabetic" by the Unicode standard.
- true if the character is "Alphabetic"
isAnySpace
public static boolean isAnySpace(char c)
Determines if the character represents any kind of space.
- True if the character represents any kind of space
isBreakableSpace
public static boolean isBreakableSpace(char c)
Helper method to determine if the character is a
space with normal behavior. Normal behavior means that
it's not non-breaking.
- True if the character is a normal space
isFixedWidthSpace
public static boolean isFixedWidthSpace(char c)
Method to determine if the character is a (breakable) fixed-width space.
c
- the character to check
- true if the character has a fixed-width
isNonBreakableSpace
public static boolean isNonBreakableSpace(char c)
Method to determine if the character is a nonbreaking
space.
- True if the character is a nbsp
isZeroWidthSpace
public static boolean isZeroWidthSpace(char c)
Method to determine if the character is a zero-width space.
c
- the character to check
- true if the character is a zero-width space
