Detailed Description

template<typename HeadT, int HeadLevel>
struct openvdb::v9_0::tree::NodeChain< HeadT, HeadLevel >

NodeChain<RootNodeType, RootNodeType::LEVEL>::Type is a openvdb::TypeList that lists the types of the nodes of the tree rooted at RootNodeType in reverse order, from LeafNode to RootNode.

For example, if RootNodeType is

RootNode<InternalNode<InternalNode<LeafNode> > >

then NodeChain::Type is

openvdb::TypeList<
    LeafNode,
    InternalNode<LeafNode>,
    InternalNode<InternalNode<LeafNode> >,
    RootNode<InternalNode<InternalNode<LeafNode> > > >

Note

Use the following to get the Nth node type, where N=0 is the LeafNodeType:

NodeChainType::Get<N>;
