How to map #define in enum

[luxingxiao]

Like this:

enum idl_type {
  IDL_NULL = 0u,
  IDL_TYPEDEF = (1llu<<19),
  /* constructed types */
  IDL_STRUCT = (1u<<17),
  IDL_UNION = (1u<<16),
  IDL_ENUM = (1u<<15),
  IDL_BITMASK = (1u<<18),
  /* template types */
  IDL_SEQUENCE = (1llu<<14),
  IDL_STRING = (1llu<<13),
  IDL_WSTRING = (1llu<<12),
  IDL_FIXED_PT = (1llu<<11),
  /* simple types */
  /* miscellaneous base types */
#define IDL_BASE_TYPE (1llu<<10)
#define IDL_UNSIGNED (1llu<<0)
  IDL_CHAR = (IDL_BASE_TYPE | (1u<<1)),
  IDL_WCHAR = (IDL_BASE_TYPE | (2u<<1)),
  IDL_BOOL = (IDL_BASE_TYPE | (3u<<1)),
  IDL_OCTET = (IDL_BASE_TYPE | (4u<<1) | IDL_UNSIGNED),
  IDL_ANY = (IDL_BASE_TYPE | (5u<<1)),
  /* integer types */
#define IDL_INTEGER_TYPE (1llu<<9)
  IDL_SHORT = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (1u<<1)),
  IDL_USHORT = (IDL_SHORT | IDL_UNSIGNED),
  IDL_LONG = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (2u<<1)),
  IDL_ULONG = (IDL_LONG | IDL_UNSIGNED),
  IDL_LLONG = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (3u<<1)),
  IDL_ULLONG = (IDL_LLONG | IDL_UNSIGNED),
  /* fixed size integer types overlap with legacy integer types in size, but
     unique identifiers are required for proper syntax errors. language
     bindings may choose to map onto different types as well */
  IDL_INT8 = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (4u<<1)),
  IDL_UINT8 = (IDL_INT8 | IDL_UNSIGNED),
  IDL_INT16 = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (5u<<1)),
  IDL_UINT16 = (IDL_INT16 | IDL_UNSIGNED),
  IDL_INT32 = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (6u<<1)),
  IDL_UINT32 = (IDL_INT32 | IDL_UNSIGNED),
  IDL_INT64 = (IDL_BASE_TYPE | IDL_INTEGER_TYPE | (7u<<1)),
  IDL_UINT64 = (IDL_INT64 | IDL_UNSIGNED),
  /* floating point types */
#define IDL_FLOATING_PT_TYPE (1llu<<8)
  IDL_FLOAT = (IDL_BASE_TYPE | IDL_FLOATING_PT_TYPE | 1u),
  IDL_DOUBLE = (IDL_BASE_TYPE | IDL_FLOATING_PT_TYPE | 2u),
  IDL_LDOUBLE = (IDL_BASE_TYPE | IDL_FLOATING_PT_TYPE | 3u)
};

We need to tell JavaCPP to not try to map those as final variables like this:

[luxingxiao]

These "define" are not mapped to final variables. The problem is that 'IDL_BASE_TYPE', 'IDL_UNSIGNED', 'IDL_INTEGER_TYPE' and 'IDL_FLOATING_PT_TYPE' type definition will be missing.

Mapping #define to final variables inside enum like that doesn't work very well right now, that needs to be fixed up a bit.
