Class: Chef::CookbookCollection
- Defined in:
- lib/chef/cookbook/cookbook_collection.rb
Overview
Chef::CookbookCollection
This class is the consistent interface for a node to obtain its cookbooks by name.
This class is basically a glorified Hash, but since there are several ways this cookbook information is collected, (e.g. CookbookLoader for solo, hash of auto-vivified Cookbook objects for lazily-loaded remote cookbooks), it gets transformed into this.
