castFrom<S, T> method
- Stream<
S> source
Adapts source
to be a Stream<T>
.
This allows source
to be used at the new type, but at run-time it
must satisfy the requirements of both the new type and its original type.
Data events created by the source stream must also be instances of T
.
Implementation
static Stream<T> castFrom<S, T>(Stream<S> source) =>
new CastStream<S, T>(source);
