示例1: toWString
WString dami::toWString(const unicode_t buf[], size_t len)
{
WString str;
str.reserve(len);
for (size_t i = 0; i < len; ++i)
{
str += static_cast<WString::value_type>(buf[i]);
}
return str;
}示例2: toString
/*
* Returns the VCard - iCal string fro this VObject.
* Note:
* The returned WCHAR* is new allocated, must be freed by the caller.
*/
WCHAR* VObject::toString() {
WString strVObject;
bool is_30 = false;
if (version) {
is_30 = !wcscmp(getVersion(), TEXT("3.0"));
}
// *** FIXME ***
// By now folding feature not supported on server...
bool useFolding = false;
// let's reserve some space to avoid reallocation in most cases
strVObject.reserve(5000);
for (int i=0; i<properties->size(); i++) {
VProperty *prop = getProperty(i);
WCHAR* propString = prop->toString(version);
WCHAR* valueConv = NULL;
// Folding
if (useFolding && wcslen(propString) > VCARD_MAX_LINE_LEN) {
valueConv = folding(propString, VCARD_MAX_LINE_LEN);
strVObject.append(valueConv);
}
else {
strVObject.append(propString);
}
strVObject.append(RFC822_LINE_BREAK);
if (propString) {
delete [] propString; propString = NULL;
}
if (valueConv) {
delete [] valueConv; valueConv = NULL;
}
}
// memory must be free by caller with delete []
WCHAR *str = wstrdup(strVObject);
return str;
