Forest

A Forest stores multiple trees and provides a simple, array-like interface for accessing and iterating over them.

In practice, forests are useful when your geometry is disconnected (like in a multibody problem): each connected component becomes its own tree, and all trees are grouped into one container.

Using a Forest

The example below focuses on how to use a forest once it is available.

@show length(forest)

for tree in forest
    println("Tree with ", H2Trees.numberofnodes(tree), " nodes")
end

length(forest) = 2
Tree with 21 nodes
Tree with 21 nodes

length(forest) returns the number of component trees, and iterating over forest yields each tree in sequence.

Working with Forest

Forest supports the usual collection operations:

• length(forest) gives the number of trees.
• forest[i] accesses the i-th tree.
• for tree in forest iterates through all trees.

More forest-related functionality and convenience utilities will be added in future releases.
