示例1: prepareImpl

	//---------------------------------------------------------------------
	bool Page::prepareImpl(StreamSerialiser& stream, PageData* dataToPopulate)
	{

		// Now do the real loading
		if (!stream.readChunkBegin(CHUNK_ID, CHUNK_VERSION, "Page"))
			return false;

		// pageID check (we should know the ID we're expecting)
		uint32 storedID;
		stream.read(&storedID);
		if (mID != storedID)
		{
			LogManager::getSingleton().stream() << "Error: Tried to populate Page ID " << mID
				<< " with data corresponding to page ID " << storedID;
			stream.undoReadChunk(CHUNK_ID);
			return false;
		}

		PageManager* mgr = getManager();
		
		while(stream.peekNextChunkID() == CHUNK_CONTENTCOLLECTION_DECLARATION_ID)
		{
			const StreamSerialiser::Chunk* collChunk = stream.readChunkBegin();
			String factoryName;
			stream.read(&factoryName);
			stream.readChunkEnd(CHUNK_CONTENTCOLLECTION_DECLARATION_ID);
			// Supported type?
			PageContentCollectionFactory* collFact = mgr->getContentCollectionFactory(factoryName);
			if (collFact)
			{
				PageContentCollection* collInst = collFact->createInstance();
