Instance Method Details

#depends_on(*depends) ⇒ Object

Introduce dependencies manually

Dependencies are calculated from “options” recursive structure by traversal and location of all dependencies automatically. If some dependency is not logical/parametrical but purely chronological, it can be introduced into the dependency list with this method.
