Detailed Description

template<typename PrevItemT, typename NodeVecT, size_t VecSize, Index _Level>
class openvdb::v8_1::tree::IterListItem< PrevItemT, NodeVecT, VecSize, _Level >

An IterListItem is an element of a compile-time linked list of iterators to nodes of different types.

The list is constructed by traversing the template hierarchy of a Tree in reverse order, so typically the elements will be a LeafNode iterator of some type (e.g., ValueOnCIter), followed by one or more InternalNode iterators of the same type, followed by a RootNode iterator of the same type.

The length of the list is fixed at compile time, and because it is implemented using nested, templated classes, much of the list traversal logic can be optimized away.

Member Function Documentation

bool down ( Index  lvl)
inline

If the iterator at level lvl of the tree points to a child node, initialize the next iterator in this list with that child node.

Index getChildDim ( Index  lvl) const
inline
Coord getCoord ( Index  lvl) const
inline

Return the global coordinates of the voxel or tile to which the iterator at level lvl of the tree is currently pointing.

void getNode ( Index  lvl,
NodeT *&  node 
) const
inline

Return the node over which this list element's iterator iterates.

void getNode ( Index  lvl,
OtherNodeT *&  node 
) const
inline

Return the node over which one of the following list elements' iterator iterates.

const NCValueT& getValue ( Index  lvl) const
inline

Return the value to which the iterator at level lvl of the tree points.

Index64 getVoxelCount ( Index  lvl) const
inline

Return the number of (virtual) voxels spanned by a tile value or child node.

void initLevel ( Index  lvl,
OtherIterListItemT &  otherListItem 
)
inline

Initialize the iterator for level lvl of the tree with the node over which the corresponding iterator of otherListItem is iterating.

For example, if otherListItem contains a LeafNode::ValueOnIter, initialize this list's leaf iterator with the same LeafNode.

bool isValueOn ( Index  lvl) const
inline

Return true if the iterator at level lvl of the tree points to an active value.

void modifyValue ( Index  lvl,
const ModifyOp &  op 
) const
inline

Apply a functor to the item to which this iterator is pointing.

Note
Not valid when IterT is a const iterator type
bool next ( Index  lvl)
inline

Increment the iterator at level lvl of the tree.

IterListItem& operator= ( const IterListItem< PrevItemT, NodeVecT, VecSize, _Level > &  other)
inline
Index pos ( Index  lvl) const
inline

Return The table offset of the iterator at level lvl of the tree.

void setIter ( const IterT iter)
inline
void setIter ( const OtherIterT &  iter)
inline
void setValue ( Index  lvl,
const NCValueT val 
) const
inline

Set the value (to val) to which the iterator at level lvl of the tree points and mark the value as active.

Note
Not valid when IterT is a const iterator type
void setValueOff ( Index  lvl) const
inline

Mark the value to which the iterator at level lvl of the tree points as inactive.

Note
Not valid when IterT is a const iterator type
void setValueOn ( Index  lvl,
bool  on = true 
) const
inline

Set the value (to val) to which the iterator at level lvl of the tree points and mark the value as active if on is true, or inactive otherwise.

Note
Not valid when IterT is a const iterator type
bool test ( Index  lvl) const
inline

Return true if the iterator at level lvl of the tree has not yet reached its end.

void updateBackPointers ( PrevItemT *  prev)
inline
