return nullptr;

// from ScrollingTreeStateNodes.

}示例2: setScrollPlatformLayer
// This copy constructor is used for cloning nodes in the tree, and it doesn't make sense
// to clone the relationship pointers, so don't copy that information from the original
// node.

, m_changedProperties(stateNode.changedProperties())
, m_parent(0)
{
// FIXME: why doesn't this set the GraphicsLayer?
setScrollPlatformLayer(stateNode.platformScrollLayer());
}示例3:
void ArgumentCoder<ScrollingStateNode>::encode(ArgumentEncoder& encoder, const ScrollingStateNode& node)
{
encoder.encodeEnum(node.nodeType());
encoder << node.scrollingNodeID();
encoder << node.parentNodeID();
encoder << node.changedProperties();

}示例4: setLayer
// This copy constructor is used for cloning nodes in the tree, and it doesn't make sense
// to clone the relationship pointers, so don't copy that information from the original node.
