join method
- @override
Combines the string representation of elements into a single string.
Each element is converted to a string using its Object.toString
method.
If separator
is provided, it is inserted between element string
representations.
The returned future is completed with the combined string when the stream is done.
If the stream contains an error, or if the call to Object.toString
throws, the returned future is completed with that error,
and processing stops.
Implementation
@override
AsObservableFuture<String> join([String separator = ""]) =>
new AsObservableFuture<String>(_stream.join(separator));
