Detailed Description

template<typename _TreeType, bool IsSafe = true, Index CacheLevels = _TreeType::DEPTH-1, typename MutexType = tbb::null_mutex>
class openvdb::OPENVDB_VERSION_NAME::tree::ValueAccessor< _TreeType, IsSafe, CacheLevels, MutexType >

When traversing a grid in a spatially coherent pattern (e.g., iterating over neighboring voxels), request a ValueAccessor from the grid (with Grid::getAccessor()) and use the accessor's getValue() and setValue() methods. These will typically be significantly faster than accessing voxels directly in the grid's tree.

A ValueAccessor caches pointers to tree nodes along the path to a voxel (x, y, z). A subsequent access to voxel (x', y', z') starts from the cached leaf node and moves up until a cached node that encloses (x', y', z') is found, then traverses down the tree from that node to a leaf, updating the cache with the new path. This leads to significant acceleration of spatially-coherent accesses.

Parameters
_TreeTypethe type of the tree to be accessed [required]
IsSafeif IsSafe = false then the ValueAccessor will not register itself with the tree from which it is consturcted (see warning).
CacheLevelsthe number of nodes to be cached, starting from the leaf level and not including the root (i.e., CacheLevels < DEPTH), and defaulting to all non-root nodes
MutexTypethe type of mutex to use (see note)
Warning
If IsSafe = false then the ValueAccessor will not register itself with the tree from which it is constructed. While in some rare cases this can lead to better performance (since it avoids the small overhead of insertion on creation and deletion on destruction) it is also unsafe if the tree is modified. So unless you're an expert it is highly recommended to set IsSafe = true, which is the default. However if you know that the tree is no being modifed for the lifespan of the ValueAccessor AND the work performed per ValueAccessor is small relative to overhead of registering it you should consider setting IsSafe = false. If this improves performance you should really rewrite your code so as to better amortize the construction of the ValueAccessor, i.e. reuse it as much as possible!
Note
If MutexType is a TBB-compatible mutex, then multiple threads may safely access a single, shared accessor. However, it is highly recommended that, instead, each thread be assigned its own, non-mutex-protected accessor.
