A [[TextWriter]] is a sort of character output stream. It implements the cycle detection and formatting capabilities in E's primary printing mechanisms, [[Object E#toString/1|E#toString/1]] and [[Miranda __printOn/1]].

{{XXX|...}}

The TextWriter supplied to __printOn is invalid after __printOn returns.

? var stream := null
? def capturer {
> to __printOn(s :TextWriter) :void {
> s.print("<capturer>")
> stream := s
> }
> }
# value: <capturer>

The particular problem might change, but anything but # stdout: Oops! is okay.

? stream.print("Oops!")
# problem: <NullPointerException>
