More complex hierarchies, or the association with delivery or
order numbers, can only be done at a higher level such as an
AutoID Node.
SimplePackSend
This data processor does a simple packing operation assuming a
single read point. A read point could be composed of several
physical readers, but the algorithm regards them as one.
Like HierarchyBuilderSend, it builds RFID events into simple
hierarchies. An example is the building of a pallet with
information about the cases contained on the pallet.
The following assumptions are made:
• We have a simple hierarchy of one single container,
containing an unlimited number of contained objects.
• The first tag seen is interpreted as the container.
• No new container object appears before the previous one has
disappeared (physically impossible for this to happen).
• No contained objects appear if there is no container object.
Should this happen, the contained object is interpreted as a
container and we cannot recognize this situation as error.
How the building is done depends upon the option setting.
LowPassFilter
Shortly buffers events to filter out false "disappeared" events. This
data processor is usually the first one in a chain.
SelectedFieldEnricher
Reads data from selected data fields of the tag and adds this data
to the event. It uses the FieldNameMapper to map from logical
field names to physical addresses on the tag.
Send
Transforms the internal event data structure and sends the
information to registered recipients.
TagBitsFilter
Filters tag events based on the contents of the tag fields. You can
specify a bit mask and value used to filter tags. TagBitsFilters can
filter on the contents of any tag field defined in the field map
including the EPC ID.
