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.
|
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.
|
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.
The following table describes all characters that this method considers a whitespace character.
