StringConversionSink class - dart:convert library (original) (raw)

A sink for converters to efficiently transmit String data.

Instead of limiting the interface to one non-chunked String it accepts partial strings or can be transformed into a byte sink that accepts UTF-8 code units.

The StringConversionSink class provides a default implementation ofadd, asUtf8Sink and asStringSink.
