Unnamed enum | Constants for this component. |
Category | Set of character categories supported by this component. |

|---|---|
isAll | Return true if the specified character is in the ALL category (i.e., [0-377]), and false otherwise. Note that this function always returns true, but is provide for completeness. |

isGraph | Return true if the specified character is in the GRAPH category (i.e., any printable character except SPACE), and false otherwise. |

isLower | Return true if the specified character is in the LOWER category (i.e., [a-z]), and false otherwise. |
isNone | Return true if the specified character is in the NONE category (i.e., []), and false otherwise. Note that this function always returns false, but is provided for completeness. |
isOdigit | Return true if the specified character is in the ODIGIT category (i.e., [0-7]), and false otherwise. |
isPrint | Return true if the specified character is in the PRINT category (i.e., any printable character including SPACE), and false otherwise. |

isSpace | Return true if the specified character is in the SPACE category (i.e., [space|tab|CR|NL|VT|FF]), and false otherwise. |
isUpper | Return true if the specified character is in the UPPER category (i.e., [A-Z]), and false otherwise. |
isXdigit | Return true if the specified character is in the XDIGIT category (i.e., [0-9A-Fa-f]), and false otherwise. |
numAll | Return the number of characters in the category ALL. Note that the character string returned by the stringAll method is of length 255, but the terminating null is part of the set. |

numAlpha | Return the number of characters in the category ALPHA (i.e., [A-Za-z]). |
numAlund | Return the number of characters in the category ALUND (i.e., [ALPHA|]). |
numAscii | Return the number of characters in the category ASCII (i.e., [0-177]). |
numCategory | Return the number of characters in the specified category. |
numCntrl | Return the number of characters in the category CNTRL (i.e., [1-37] and 177). |
numDigit | Return the number of characters in the category DIGIT (i.e., [0-9]). |
numGraph | Return the number of characters in the category GRAPH (i.e., any printable character except SPACE), and false otherwise. |
numIdent | Return the number of characters in the category IDENT (i.e., [ALNUM|]). |
numLower | Return the number of characters in the category LOWER (i.e., [a-z]). |
numNone | Return the number of characters in the category NONE. Note that the string returned by the stringNone method is empty. |
numOdigit | Return the number of characters in the category ODIGIT (i.e., [0-7]). |
numPrint | Return the number of characters in the category PRINT (i.e., any printable character including SPACE). |
numPunct | Return the number of characters in the category PUNCT (i.e., any printable character other than SPACE or ALNUM). |
numSpace | Return the number of characters in the category SPACE (i.e., [space|tab|CR|NL|VT|FF]). |
numUpper | Return the number of characters in the category UPPER (i.e., [A-Z]). |
numXdigit | Return the number of characters in the category XDIGIT (i.e., [0-9A-Fa-f]). |
stringAll | Return a null-terminated string consisting of all characters in the category ALL (i.e., [0-377]), ordered by increasing character codes. Note that this string, if printed, may appear to be of length 0 because the NULL character is part of the set and appears first. |
stringAlnum | Return a null-terminated string consisting of all characters in the category ALNUM (i.e., [0-9A-Za-Z]), ordered by increasing character codes. |
stringAlpha | Return a null-terminated string consisting of all characters in the category ALPHA (i.e., [A-Za-z]), ordered by increasing character codes. |
stringAlund | Return a null-terminated string consisting of all characters in the category ALUND (i.e., [ALPHA|]), ordered by increasing character codes. |
stringAscii | Return a null-terminated string consisting of all characters in the category ASCII (i.e., [0-177]), ordered by increasing character codes. Note that this string, if printed, may appear to be of length 0 because the NULL character is part of the set and appears first. |
stringCategory | Return a null-terminated string consisting of all characters in the specified category, ordered by increasing character codes. Note that for category values of CNTRL, ASCII, and ALL`, this string, if printed, may appear to be of length 0 because the NULL character is part of the set and appears first. |
stringCntrl | Return a null-terminated string consisting of all characters in the category CNTRL (i.e., [0-37] and 177), ordered by increasing character codes. Note that this string, if printed, may appear to be of length 0 because the NULL character is part of the set and appears first. |
stringDigit | Return a null-terminated string consisting of all characters in the category DIGIT (i.e., [0-9]), ordered by increasing character codes. |
stringGraph | Return a null-terminated string consisting of all characters in the category GRAPH (i.e., any printable character except SPACE), ordered by increasing character codes. |

stringUpper | Return a null-terminated string consisting of all characters in the category UPPER (i.e., [A-Z]), ordered by increasing character codes. |
stringXdigit | Return a null-terminated string consisting of all characters in the category XDIGIT (i.e., [0-9A-Fa-f]), ordered by increasing character codes. |
toAscii | Return a null-terminated string representation of the specified character category enumerator that is identical to the enumerator name. |
toLower | Return the character in the LOWER category corresponding to the specified input character from the UPPER category or input itself if input is not in category UPPER. |
toUpper | Return the character in the UPPER category corresponding to the specified input character from the LOWER category or input itself if input is not in category LOWER. |
