示例1: addChild

void RenderRubyRun::addChild(RenderObject* child, RenderObject* beforeChild)
{
    ASSERT(child);

    if (child->isRubyText()) {
        if (!beforeChild) {
            // RenderRuby has already ascertained that we can add the child here.
            ASSERT(!hasRubyText());
            // prepend ruby texts as first child
            RenderBlockFlow::addChild(child, firstChild());
        }  else if (beforeChild->isRubyText()) {
            // New text is inserted just before another.
            // In this case the new text takes the place of the old one, and
            // the old text goes into a new run that is inserted as next sibling.
            ASSERT(beforeChild->parent() == this);
            RenderObject* ruby = parent();
            ASSERT(ruby->isRuby());
            RenderBlock* newRun = staticCreateRubyRun(ruby);
            ruby->addChild(newRun, nextSibling());
            // Add the new ruby text and move the old one to the new run
            // Note: Doing it in this order and not using RenderRubyRun's methods,
            // in order to avoid automatic removal of the ruby run in case there is no
            // other child besides the old ruby text.
            RenderBlockFlow::addChild(child, beforeChild);
            RenderBlockFlow::removeChild(beforeChild);
            newRun->addChild(beforeChild);
        } else if (hasRubyBase()) {
            // Insertion before a ruby base object.
            // In this case we need insert a new run before the current one and split the base.
            RenderObject* ruby = parent();
            RenderRubyRun* newRun = staticCreateRubyRun(ruby);
            ruby->addChild(newRun, this);
            newRun->addChild(child);
            rubyBaseSafe()->moveChildren(newRun->rubyBaseSafe(), beforeChild);
        }
    } else {
        // child is not a text -> insert it into the base
        // (append it instead if beforeChild is the ruby text)
        RenderRubyBase* base = rubyBaseSafe();
        if (beforeChild == base)
            beforeChild = base->firstChild();
        if (beforeChild && beforeChild->isRubyText())
            beforeChild = 0;
        ASSERT(!beforeChild || beforeChild->isDescendantOf(base));
        base->addChild(child, beforeChild);
    }
}
