The library of pinyin4cpp:

The pinyin4cpp is a c plus plus library supporting convertion between Chinese characters and hanyu pinyin that based on Qt.

Data structure:PinyinUnit

PinyinUnit as a base data structure to save the string that Chinese characters

static void parse(PinyinSearchUnit &pinyinSearchUnit);
static bool match(PinyinSearchUnit &pinyinSearchUnit,QString &search);
static QString getFirstLetter(PinyinSearchUnit &pinyinSearchUnit);
static QString getFirstCharacter(PinyinSearchUnit &pinyinSearchUnit);
static QString getSortKey(PinyinSearchUnit &pinyinSearchUnit);
static bool isChineseCharacter(QChar &chr);

Function call:

PinyinUtil::parse(...);
T9Util::match(...);
QwertyUtil::match(...);
PinyinUtil::getSortKey(...);
PinyinUtil::getFirstLetter(...);
PinyinUtil::getFirstCharacter(...);
PinyinUtil::isChineseCharacter(...);

Function call in detail:

pinyinsearch4cpp Dependent on pinyin4cpp.

The first step:  Data parsing  (ps:Must init baseData of PinyinSearchUnit before parse)
    * (PinyinUtil::parse(...))
The second step: Data matching 
    * (T9Util::match(...) or QwertyUtil::match(...))

For details, please see project pinyinsearchdemo.
