IDL reverse engineering limitations

There are some limitations on the use of the reverse IDL feature in this version. Some of the missing functions are intentionally documented to give you a correct insight of the situation.

Pre-processing

The pre-processing function in IDL is not handled in this version. It has the following effect, as shown in the example below:

When a # symbol appears at the beginning of a line, the reverse feature processes both "if" and "else" values during reverse.

# IF

   true

# ELSE

   false

# ENDIF

Unsupported tags

The following tags are not reversed in this version:

fixed <8, 4>
fixed <8, 2>
sequence <short, 4>
sequence
[wire_marshal( wireVARIANT )]

An example is shown below:

struct bar {
    fixed <8, 4> high_scale;
    fixed <8, 2> low_scale;
};

struct bar {
    long val;
    sequence <short, 4> my_shorts;
};

typedef sequence<LinkKind>LinkKinds;
typedef [wire_marshal( wireVARIANT )]  struct tagVARIANT  VARIANT;
