|  | ## Loop Collection

#### Synopsis

Iterates over a collection of objects.

#### Description

The subprocess of this operator is executed once for every entry in the input collection. If "unfold" is checked, the input list is flattened, i.e. nested collections are replaced by their entries. The outputs of the iterations are grouped into collections again. Since the inner subprocess can have multiple results, the output of the Loop Collection operator consits of multiple collections, one for each result of the subprocess. Objects can be grouped into a collection using the Collect operator.

#### Input

- collection: expects: IOObjectCollection

#### Output

- output 1:

#### Parameters
