Instance Method Details

#add_recursive(path, content) ⇒ Object Also known as: add_path

Has the same effect of using Tree::TreeNode#<< multiple time but with a filepath-like syntax:

node.add_recursive '/path/to/a/deep/node', "MyContent"

A leading slash in the path means that it is absolute (i.e. refers to the tree root)

path may be an Array (instead of String), but this is intended for “private” use only (i.e. recursive calls)
