示例1: getWordBoundary
Dart_Handle Paragraph::getWordBoundary(unsigned offset) {
String text;
int start = 0, end = 0;
for (RenderObject* object = m_renderView.get(); object;
object = object->nextInPreOrder()) {
if (!object->isText())
continue;
RenderText* renderText = toRenderText(object);
text.append(renderText->text());
}
TextBreakIterator* it = wordBreakIterator(text, 0, text.length());
if (it) {
end = it->following(offset);
if (end < 0)
end = it->last();
start = it->previous();
}
Dart_Handle result = Dart_NewList(2);
Dart_ListSetAt(result, 0, ToDart(start));
Dart_ListSetAt(result, 1, ToDart(end));
return result;
}示例2: findWordBoundary
void findWordBoundary(const UChar* chars, int len, int position, int* start, int* end)
{
TextBreakIterator* it = wordBreakIterator(chars, len);
*end = it->following(position);
if (*end < 0)
*end = it->last();
*start = it->previous();
