cast<RS, RT> method
Provides a StreamTransformer<RS, RT>
view of this stream transformer.
The resulting transformer will check at run-time that all data events
of the stream it transforms are actually instances of S
,
and it will check that all data events produced by this transformer
are actually instances of RT
.
Implementation
@override
StreamTransformer<RS, RT> cast<RS, RT>() {
return StreamTransformer.castFrom(this);
}
