## Detailed Description

template<typename OpType, typename DenseType>
class openvdb::v11_0::tools::SparseExtractor< OpType, DenseType >

Functor-based class used to extract data that satisfies some criteria defined by the embedded `OpType` functor. The `extractSparseTree` function wraps this class.
