Examining Microsoft's J/Direct

By Andrew Wilson

Dr. Dobb's Journal January 1998

//Native C Structure
typedef struct _MYSTRUCT
{
    DWORD dwLen;
    char szMyString[24];
} MYSTRUCT;
//J/Direct Structure Conversion for Fixed Length Types
/** @dll.struct() */
{
    int dwLen;
    /** @dll.structmap([type=FIXEDARRAY, size=24]) */
    char szMyString[];
}
//J/Direct Structure Conversion for String Types
/** @dll.struct() */
class MYSTRUCT
{
    int dwLen;
    /** @dll.structmap([type=char[24]) */
    String szMyString; // converted to a string object
}

Example 4: Conversions that must occur whenever fixed-length array objects are created.
