A Traversable represents an Iterable type and adds useful functionality that can be applied to any Iterable type.
Traversable contains a large range of utility methods including - operators are lazy if the traversable is lazy.
- combine : partial reduction operator, use this for lazy / terminating reduction or folding of infinite data structures
- cycle : repeats the data inside the traversable
- groupedXXX : groups the data in the traversable
- slidingXXX : create sliding windows over the data in the traversable
- onEmpty : gracefully handle an empty traversable
- scanLeft / scanRight : fold over the traversable creating a new traversable of the intermediate outputs
- takeXXX / dropXXX : advanced take / drop operators
ReactiveSeq.generate(this::process)
.map(data->data.isSuccess())
.combine((a,b)-> a ? false : true, (a,b) -> a|b)
.findFirst(); //terminating reduction on infinite data structure
ListX.of(1,2,3)
.dropRight(1);
//ListX[1,2]
