co.multiply.pathling.accumulator — co.multiply/pathling 0.2.1

Mutable accumulator utilities for efficient collection building. Uses ArrayList on CLJ, JS array on CLJS.

acc-append! clj/s macro

(acc-append! acc v)

Append a single value to the accumulator. Mutates in place, returns the accumulator.

acc-append-many! clj/s macro

(acc-append-many! acc many)

Append all elements from a sequential collection to the accumulator. Mutates in place, returns the accumulator.

acc-get clj/s macro

(acc-get acc idx)

Get element at index position from the accumulator.

acc-init-append! clj/s macro

(acc-init-append! acc v)

Append a value to the accumulator, lazily initializing if nil. Returns the (possibly new) accumulator.

acc-set! clj/s macro

(acc-set! acc idx v)

Set element at index position in the accumulator. Returns the value.

acc-size clj/s macro

(acc-size acc)

Return the number of elements in the accumulator.

accumulator clj/s macro

(accumulator)

(accumulator initial-size)

Create a new mutable accumulator. Optionally accepts an initial-size for preallocation when final size is known. In ClojureScript, returns a raw JS array (preallocation hint is ignored).

accumulator->list clj/s

(accumulator->list acc)

Convert an accumulator to a list.

accumulator->vec clj/s

(accumulator->vec acc)

Convert an accumulator to a persistent vector.

arr-push! cljs

(arr-push! arr v)
