+ |:--- |:--- |:--- |
+ |`.parallel` | boolean | Flag to indicate parallel action execution |
+
+- DigiContainerProcessor
+
+ Base class of all actors dealing with one of more containers sequentially.<br/>
+
+- DigiContainerSequence
+
+ Sequencer of `DigiContainerProcessor` entities with container based work load splitting.<br/>
+
Properties: <br/>
|**Property** |**Data type** |**Description** |
|:--- |:--- |:--- |
- |`.input` | vector<string> | List of input files to be processed |
+ |`.parallel` | boolean | Flag to indicate parallel action execution |
+
+- DigiContainerSequenceAction
+
+ Specialization of the `DigiEventAction`.
+ Process continers from the data store according to the `input_segment` and the `input_mask`.
+ Output of workers is delivered to the `output_segment` with mask `output_mask`.
+

+ |`.output_mask` | integer | Mask identifier of the output containers |
+
+- DigiMultiContainerProcessor
+
+ Specialization of the `DigiEventAction`.
+ Process multiple containers from the data store according to the `input_segment` and the list of `input_masks`. Allows to re-use the same container action.
+ Output of workers is delivered to the `output_segment` with mask `output_mask`.
