This attribute specifies the token collection type and determines the behavior of all further operations with regard to the collection:

 

- Folder: from now on, the collection is considered as a set of tokens. When this collection will be processed by a further operation, each token forming part of the collection will be individually processed. However, the resources will be allocated for the whole collection and freed after processing of the last collection item.

The collection exits the operation and all further ones only when all its constituent tokens have been processed.

Example: documents are placed in a folder. Each document in the folder is processed individually but the folder does not pass from operation to operation until all the documents have been processed.

 

- Pack: the tokens collected become a single token. This macro token is processed once by all subsequent operations.

Example: bottles of mineral water are grouped in a pack. From now on, operations will process the pack of bottles as a single unit and not the individual bottles.
