Detailed Description

Structure representing "cooked" entry from UnicodeData.txt.

(see www.unicode.org). Note, 3 of the values in this structure could be enums, but I want them to take as little space as possible, and I can't guarentee that enum will be a byte on all platforms. (have to be sure, because this struct is read out of a file.

static const UCDATA* UCDATA::GetCharData

(

MIUNICODE

ucval

)

[static]

Return the CHARDATA for a given Unicode character.

May return NULL if no data exists for a given Unicode char.

const MIUNICODE* UCDATA::GetComponants

(

)

const [inline]

Get the list of componants for this character If numcomp > 0, the unicode character can be decomposed into that many componants.

This method will get the list of componants, assuming you got the componant by calling UCDATA::GetCharData()

Member Data Documentation

MIUNICODE UCDATA::altcase

If cagegory == UCCAT_Lu, (Letter, Uppercase), this will be the Unicode value of the lowercase version of the same letter.

If category == UCCAT_Ll (Letter, Lowercase) this will be the uppercase version of the same letter

Definition at line 604 of file ucstring.h.

UINT8 UCDATA::biditag

Bidirectional category tag.

Enums defined below and explained in Chapter 3 of the Unicode Standard

Definition at line 634 of file ucstring.h.

UINT8 UCDATA::category

General character category.

This is one of the UCCAT enums defined below. The enum is based on the two letter code from UnicodeData.txt, so if UnicodeData.txt says a character is Lo (Letter, Other), the enum is UCCAT_Lo.

Definition at line 630 of file ucstring.h.

UINT8 UCDATA::decomptag

Decomposition tag.

Definition at line 637 of file ucstring.h.

MIUNICODE UCDATA::firstcomp

Unicode value of the first composite character that starts with this Unicode value.

For example, Unicode value 0x0627 (ARABIC LETTER ALEF) might have a firstcomp of 0x0626 (ARABIC LETTER ALEF WITH HAMZA ABOVE). Due to the recursive nature of composition, this can't be done as a single linked list. ARABIC LETTER ALEF WITH HAMZA ABOVE might have a nextcomp of ARABIC LETTER ALEF WITH HAMZA BELOW (next in the chain of things that started with ARABIC LETTER ALEF. But it might have a firstcomp of ARABIC LETTER ALEF WITH HAMZA ABOVE FINAL FORM (beginning a chain of things starting with ARABIC LETTER ALEF WITH HAMZA ABOVE)

Definition at line 618 of file ucstring.h.

MIUNICODE UCDATA::nextcomp

Unicode value of the first composite character that starts with this Unicode value.

For example, Unicode value 0x00E0 (ARABIC SMALL LETTER A WITH GRAVE) might have a nextcomp of 0x00E1 (ARABIC SMALL LETTER A WITH ACUTE).

Definition at line 624 of file ucstring.h.

UINT8 UCDATA::numcomp

Number of componants if this is a composite glyph or a variant of the glyph.

Definition at line 641 of file ucstring.h.

MIUNICODE UCDATA::ucval

The actual Unicode value.

Definition at line 598 of file ucstring.h.
