"state" data type & how to determine the type for some data

🚧 Developers Coding Questions

I'm writing an app. I'm saving a epoch data in "state.idleTime"

idleTime is a long Epoch number. Does the state.xxxx force the data to a string?

Is there a method that can determine the data type of some variable?

I tried the below but received the noted error.

    def obj = state.lastAC
    log.info("state class ${obj.getClass()}")

which resulted in:

Expression [MethodCallExpression] is not allowed: obj.getClass() at line number 84

SomeObject.properties.each{ log.info it}
Will tell you everything and more...

Another trick someone told me about a while back, if you don't want all the "extra" information that the above will also provide, is to just call a method that doesn't exist with your object passed as the parameter. Then, Groovy will complain that it can't find a method matching that signature, and the signature will contain the type of your object.

Once I left a call like fsdaklajsd(myObject) in code I accidentally released, and a user complained about an error in Logs. That was why. :smiley:

Thanks,

I really only wanted it to verify my assumptions of data type or my lack of knowing data type. At least for the moment.

I want to start a Hubitat "cheat sheet", this and the fact that state.xxxx will be a string no matter what you assign to it. Kinda like "enum" type.

This works for me.
Tried all sorts of things to handle null values and therefore no class, but his works.

	obj.properties.each
		{ k,v -> 
		if (v?.class)	
			log.debug  "${k}: ${v} ${v.class.name}"
		else	
			log.debug  "${k}: ${v}"
		}

Sample result
