Generialized efficient pathways involving iterators.

->iterator clj

(->iterator item)

Convert a stream or an iterable into an iterator.

ary-iter clj

(ary-iter ary-data)

Create an iterator for any primitive or object java array.

const-iterable clj

(const-iterable arg)

Return an iterable that always returns a arg.

current-iterator clj

(current-iterator item)

Return a current iterator - and iterator that retains the current object. This iterator is positioned just before the first object so it's current item is nil.

doiter clj macro

(doiter varname iterable & body)

Execute body for every item in the iterable. Expecting side effects, returns nil.

iter-cons clj

(iter-cons vv iter)

Produce a new iterator that points to vv then defers to passed in iterator.

linear-merge-iterator clj

(linear-merge-iterator iterators)

(linear-merge-iterator cmp iterators)

(linear-merge-iterator cmp p iterators)

Create a merging iterator - fast for N < 8.

once-iterable clj

(once-iterable init-fn)

(once-iterable valid? init-fn)

(once-iterable valid? init-fn update-fn)

once-iterator clj

(once-iterator valid? init-fn update-fn)

priority-queue-merge-iterator clj

(priority-queue-merge-iterator iterators)

(priority-queue-merge-iterator cmp iterators)

(priority-queue-merge-iterator cmp p iterators)

Create a priority queue merging iterator - fast for most N

queue->iterable clj

(queue->iterable queue term-symbol)

seq-once-iterable clj

(seq-once-iterable init-fn)

(seq-once-iterable valid? init-fn)

(seq-once-iterable valid? init-fn update-fn)

Iterable with efficient reduce but also contains a cached seq conversion so patterns like: (when (seq v) ...) still work
