RFID Event Manager Connectors
Zero or more connectors may be defined. Connectors are linked from input events to
other components that name them as outputs. A connector is defined by the
following properties:
■ name – The unique name for the component.
■ classname – The name of the Java class that implements the component.
■ properties – A sequence of name/value pairs that are used for the configuration
of the connector.
The supported connectors are described in the following table. For a description of
the connector’s associated properties, see the table listed in the Properties column.
Delta Reports tags leaving and entering the radio frequency
(RF) field.
See TABLE B-2.
EPC Performs a pass filter on tag EPCs. EPCs that match
the EPC mask are passed on to listeners, while other
EPCs are not.
See
TABLE B-3.
Smoothing Creates a union of EPCs discovered over the number
of specified n cycles. If an EPC was discovered in a
cycle < n, the EPC is reported, if the EPC hasn’t been
seen in more than the last n cycles, the EPC is not
reported. This filtering action is necessary because the
RFID readers do not report tags with 100% tag
accuracy.
See
TABLE B-1.
