Re: [milo-dev] Node interface

[Joe San <codeintheopen@xxxxxxxxx>]

That makes sense! It was after reading through the code and referring to the spec, I still had this question!

Ok now I have the next one: We have these NodeClasses such as Object, ObjectType and Variable, VariableType... what is the difference? My understanding is that a VariableType represents meta information about a Variable, while the Variable holds the actual data and likewise, ObjectType is like a class definition, while the object is an instance of ObjectType... did I get this correct?

Joe,

The difference can be seen in the type signatures. The getXXX methods return the attribute value, while the readXXX methods return the DataValue that contains those attribute values. This can be useful if you also need access to the StatusCode or timestamps that came back along with the attribute being read.

If you look at the implementation you'll see the getXXX methods just delegate to the corresponding readXXX and then extract the value.
