I need a concise definition of the "state of an object" in object-oriented programming (for a paper).
For about half of a day I searched for a paper that I can cite on this topic, but I couldn't find one. All the papers I found were mostly general papers on object-oriented programming and they didn't define the state of an object.
I am unsure, but my best guess is something like: The state of an object is defined by the state of the instance variables of the object.
I am searching for a definition of the state of an object and/or a reference on the topic.
(btw, could I refer to the concept as "object state" or is this uncommon?)
