Detailed Description

Identifies a unique instance of a variable.

Storage for identifying a potentially inlined instance of a variable, or a fragment thereof. This guarantees that exactly one variable instance may be identified by this class, even when that variable is a fragment of an aggregate variable and/or there is another inlined instance of the same source code variable nearby. This class does not necessarily uniquely identify that variable: it is possible that a DebugVariable with different parameters may point to the same variable instance, but not that one DebugVariable points to multiple variable instances.
