Property :: objectSpace - Get Database Object handle

The function returns the object space handle for the property handle. For transient references the function returns the object space handle that is associated with the transient reference property and not the object space handle of the property handle, which is currently set in the transient reference, which might in some cases belong to another object space.

When the property handle is invalid or when it refers to an independent transient property that does not have an object space parent, the function will throw an exception.
