Method: Abstractivator::Trees#tree_map

Defined in:
lib/abstractivator/trees/tree_map.rb

#tree_map(h) {|config| ... } ⇒ Object

Transforms a tree at certain paths. The transform is non-destructive and reuses untouched substructure. For efficiency, it first builds a “path_tree” that describes which paths to transform. This path_tree is then used as input for a data-driven algorithm.

Yields:

  • (config)

Raises:

  • (ArgumentError)
