Method: Chef::Node#expand!

Defined in:
lib/chef/node.rb

#expand!(data_source = "server") ⇒ Object

Expands the node’s run list and sets the default and override attributes. Also applies stored attributes (from json provided on the command line)

Returns the fully-expanded list of recipes, a RunListExpansion.

– TODO: timh/cw, 5-14-2010: Should this method exist? Should we instead modify default_attrs and override_attrs whenever our run_list is mutated? Or perhaps do something smarter like on-demand generation of default_attrs and override_attrs, invalidated only when run_list is mutated?
