Helper class to wrap a StreamConsumer<List<int>> and provide utility functions for writing to the StreamConsumer directly. The IOSink buffers the input given by all StringSink methods and will delay an addStream until the buffer is flushed.

When the IOSink is bound to a stream (through addStream) any call to the IOSink will throw a StateError. When the addStream completes, the IOSink will again be open for all calls.

If data is added to the IOSink after the sink is closed, the data will be ignored. Use the done future to be notified when the IOSink is closed.

Properties

Future done
read-only
Get a future that will complete when the consumer closes, or when an error occurs. This future is identical to the future returned by close.
Encoding encoding
read / write
The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable. /

Constructors

IOSink(StreamConsumer<List<int>> target, {Encoding encoding: UTF8})

Methods

add(List<int> data) → void
Adds data to the target consumer, ignoring encoding.
addError(error, [StackTrace stackTrace]) → void
Passes the error to the target consumer as an error event.
addStream(Stream<List<int>> stream) → Future
Adds all elements of the given stream to this.
close() → Future
Close the target consumer.
flush() → Future
Returns a Future that completes once all buffered data is accepted by the to underlying StreamConsumer.
write(Object obj) → void
Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer.
writeAll(Iterable objects, [String separator = ""]) → void
Iterates over the given objects and writes them in sequence.
writeCharCode(int charCode) → void
Writes the charCode to this.
writeln([Object obj = ""]) → void
Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline.
