      • getCompatibleVariableStorage

        public static VariableStorage getCompatibleVariableStorage​(Program program,

                                                           Program otherProgram)
        Convert a variable storage object from the specified program to a comparable variable storage object in the specified otherProgram. Certain variable storage (UNIQUE/HASH-based) will always produce a null return object.
        Parameters:
        program - program which contains the specified address instance
        storage - variable storage in program
        otherProgram - other program
        Returns:
        storage for otherProgram or null if storage can not be mapped to other program

        Convert a varnode from the specified program to a comparable varnode in the specified otherProgram. Certain varnode addresses spaces (UNIQUE, HASH) will always produce a null return varnode.
        Parameters:
