Detailed Description

Represents a stack-allocated object variable in the SVFIR (SVF Intermediate Representation) @inherits BaseObjVar.

This class models variables that are allocated on the stack in the program. It provides type checking functionality through LLVM-style RTTI (Runtime Type Information) methods like classof.
