C++ (Cpp) jl_field_index Examples

Example #1

File: alloc.c Project: FizzyP/julia

int jl_field_isdefined(jl_value_t *v, jl_sym_t *fld, int err)
{
    jl_datatype_t *st = (jl_datatype_t*)jl_typeof(v);
    int i = jl_field_index(st, fld, err);
    if (i == -1) return 0;
    size_t offs = jl_field_offset(st,i) + sizeof(void*);
    if (st->fields[i].isptr) {
        return *(jl_value_t**)((char*)v + offs) != NULL;
    }
    return 1;
}
