Method Detail
isHighSurrogate
()
method
public static function isHighSurrogate(charCode:int):Boolean
Language Version :
ActionScript 3.0
Runtime Versions :
Flash Player 10, AIR 1.5
Returns true if the charCode argument is a high word in a surrogate pair.
A surrogate pair represents a character with a code point that requires more
than sixteen bits to express and thus requires a combination
of two 16-bit words, a high surrogate and a low surrogate, to embody its code point.
This method can be used when processing a series of characters to
ensure that you do not inadvertently divide a surrogate pair
into incomplete halves.
Parameters
charCode:int — An integer that represents a character code.
Character codes are usually represented in hexadecimal format.
For example, the space character's character code can be
represented by the number 0x0020.
Returns
Boolean — true if charCode is the high surrogate in a surrogate pair.
isLowSurrogate
()
method
public static function isLowSurrogate(charCode:int):Boolean
Language Version :
ActionScript 3.0
Runtime Versions :
Flash Player 10, AIR 1.5
Returns true if the charCode argument is a low word in a surrogate pair.
A surrogate pair represents a character with a code point that requires more
than sixteen bits to express and thus requires a combination
of two 16-bit words, a high surrogate and a low surrogate, to embody its code point.
This method can be used when processing a series of characters to
ensure that you do not inadvertently divide a surrogate pair
into incomplete halves.
Parameters
charCode:int — An integer that represents a character code.
Character codes are usually represented in hexadecimal format.
For example, the space character's character code can be
represented by the number 0x0020.
Returns
Boolean — true if charCode is the low surrogate in a surrogate pair.
isWhitespace
()
method
public static function isWhitespace(charCode:int):Boolean
Language Version :
ActionScript 3.0
Runtime Versions :
Flash Player 10, AIR 1.5
Returns true if charCode is a whitespace character.
