[openstack-dev] [heat] [CustomResource] LifeCycle methods flow

Any pointer (document and/or code pointer) related to how the different
overridden methods are getting called when a custom resource is getting
deployed in the heat stack?

Basically just tried to annotate the h-eng log on a simple,
very-first-attempt 'hello world' resource. Noticed the log is something

2014-11-26 15:38:30.251 INFO heat.engine.plugins.helloworld [-]
[pradipm]:Inside handle_create
2014-11-26 15:38:30.257 INFO heat.engine.plugins.helloworld [-]
[pradipm]:Inside _set_param_values
2014-11-26 15:38:31.259 INFO heat.engine.plugins.helloworld [-]
[pradipm]:Inside check_create_complete
2014-11-26 15:38:44.227 INFO heat.engine.plugins.helloworld
[req-9979deb9-f911-4df4-bdf8-ecc3609f054b None demo] [pradipm]:Inside
HelloWorld ctor
2014-11-26 15:38:44.234 INFO heat.engine.plugins.helloworld
[req-9979deb9-f911-4df4-bdf8-ecc3609f054b None demo] [pradipm]:Inside

The constructor (ctor) is getting called in the flow after the
create-resource. So though understanding the flow would help.

Thanks in advance,
