CategoryPath
Holds a sequence of string components, specifying the hierarchical name of a category.

ParallelTaxonomyArrays
Returns 3 arrays for traversing the taxonomy: parents: parents[i] denotes the parent of category ordinal i. children: children[i] denotes a child of category ordinal i. siblings: siblings[i] denotes the sibling of category ordinal i. To traverse the taxonomy tree, you typically start with children[0] (ordinal 0 is reserved for ROOT), and then depends if you want to do DFS or BFS, you call children[children[0]] or siblings[children[0]] and so forth, respectively.

TaxonomyReader.ChildrenIterator
An iterator over a category's children.
