org.bytedeco.arrow.PathForest

All Implemented Interfaces:

AutoCloseable

@Namespace(value="arrow::fs")
 @NoOffset
 @Properties(inherit=arrow.class)
public class PathForest
extends Pointer

\brief A PathForest is a utility to transform a vector of FileInfo into a forest representation for tree traversal purposes. Note: there is no guarantee of a shared root. Each node in the graph wraps a FileInfo. Files are expected to be found only at leaves of the tree.
