Shouldn't all (non-final, at least) Clownfish classes be mapped to Go
interfaces? Otherwise, I don't see how objects could be upcasted. This would
mean that for every class, there'd be an interface and a struct containing the
implementation. For the implementing structs, it should work to put a
cfish_Obj pointer in the Obj struct and the parent struct in the structs of
subclasses?
type Obj interface {
ToPtr() unsafe.Pointer
}
type ObjImpl struct {
ref *C.cfish_Obj
}
type Searcher interface {
Obj
Hits(...)
}
type SearcherImpl struct {
ObjImpl
}
type IndexSearcher interface {
Searcher
}
type IndexSearcherImpl struct {
SearcherImpl
}
