Overview

Note:

Generally you do not need to create branch nodes.

Represents a branch in an AWS::S3::Tree. From a branch node you can descend deeper into the tree using Parent#children or go back to the parent node using #parent.

When enumerating nodes in an S3 tree keys grouped by a common prefix are represented as a branch node.

Branch nodes are often treated like directories.
