Don't buffer stream inside of toString()

9

`Seq` currently buffers any stream when calling `toString()` because this allows for a nice display in debuggers without wasting the stream / modifying program behaviour. However, buffering the stream has...

Add CheckedConsumer[N] and CheckedFunction[N] and add wrapper methods to Unchecked

This is the inverse operation for #214 ``` java interface Tuple { static Consumer2 consumer2(Consumer

Pass appropriate java.util.stream.Collector.Characteristics to Collector API

2

`java.util.stream.Stream` can implement some optimisations if custom `Collectors` pass hints to the `collect()` API via ` java.util.stream.Collector.Characteristics`. We should also pass these characteristics.

Seq.shuffle() (and others) should delay buffering until a terminal op requests the stream values

See comment there: https://github.com/aol/simple-react/issues/99#issuecomment-185275640 Others: - `innerJoin()` - `leftOuterJoin()` - `removeAll()` - `retainAll()` - `window()` - `zip()` eagerly allocates an `Iterator` - `SeqUtils.transform()` eagerly allocates a `Spliterator` - `reverse()` -...

Add Seq<T> onEmptySwitch(Supplier<? extends Stream<? extends T>>)

4

As suggested by @johnmcclean-aol (https://github.com/jOOQ/jOOL/issues/177#issuecomment-170689447), an `onEmptySwitch(Supplier

Avoid collecting entire partition(s), when no Comparator is provided with a window

9

When using only the frame clause (and possibly the partition function), subsequent window function evaluations can be done lazily, as they do not necessarily depend on the whole partition(s) being...

Associative _and_ identity aggregations could be calculated based on the result of the aggregation of the previous value: ``` v sum (-3, -1) current calculation better ------------------------------------------------- 1 e e...
