class CfnModel

Attributes

conditions[R]
globals[R]
line_numbers[R]
mappings[R]
parameters[R]
raw_model[RW]

if you really want it, here it is - the raw Hash from YAML.load. you'll have to mess with structural nits of CloudFormation and deal with variations between yaml/json refs and all that

resources[R]
