webkit 常用操作代码调用流程
构造 HTML/XML tokenizer
[HTML]Document::createTokenizer() [HTML]Document::implicitOpen() FrameLoader::begin(const KURL&, bool dispatch, SecurityOrigin*) FrameLoader::receivedFirstData()
Tokenizing HTML/XML document
From the moment, piece by piece of an HTML document is obtained from the network, this is what happens:
[HTML,XML]Tokenizer::write(const SegmentedString& str, bool appendData) FrameLoader::write(const char* data, int len, bool flush) FrameLoader::addData(const char* bytes, int length) FrameLoaderClientQt::committedLoad(DocumentLoader* loader, const char* data, int length) FrameLoader::committedLoad(DocumentLoader* loader, const char* data, int length) DocumentLoader::commitLoad(const char* data, int length) DocumentLoader::receivedData(const char* data, int length) FrameLoader::receivedData(const char* data, int length) MainResourceLoader::addData(const char* data, int length, bool allAtOnce) ResourceLoader::didReceivedData(const char* data, int length, long long received, bool allAtOnce) ResourceLoader::didReceiveData(ResourceHandle*, const char* data, int len, long long received)
