WebKit之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)
