Accumulators
Function
At each step of an iteration, resulting data can be memorized and stored with the OMLoop accumulators . Accumulators execute storage or other operation upon the elements they are returned successively.
There are six accumulators :
-
: ** Collect ** gathers the result of each step of a loop into a list. -
: Sum returns the sum of the collected elements. -
: Min and max return the lowest and highest value among a set of collected elements. -
: ** Counter ** counts the number of non-nil collected elements. -
: Acum allows to define specific accumulation procedures.

Inputs and Outputs
-
All accumulators but acum have a single input : this input is used for collecting the successive values during a loop.
-
All accumulator have three outputs, allowing to access their current “memory” :
- first output : executes a specific operation with each new collected element.
- second output : returns the current stat e of the accumulator’s memory,
- third output : reinitializes the memory.
