Instance Method Details

#json_create(json_hash) ⇒ Tree::TreeNode

Helper method to create a Tree::TreeNode instance from the JSON hash representation. Note that this method should NOT be called directly. Instead, to convert the JSON hash back to a tree, do:

tree = JSON.parse(the_json_hash, create_additions: true)

This operation requires the JSON gem to be available, or else the operation fails with a warning message.

Note the create_additions: true option, which is required for successfully parsing the string or hash.

Parameters:

  • json_hash (Hash) —

    The JSON hash to convert from.
