BandPass Filter
The BandPass filter is used to select a subset of events that match the specified event
source's identity. If an event matches, the Event object is passed to the listeners of
the filter, otherwise the Event object is dropped.
An event source identity matches if any of the following conditions are true:
■
An EPC identifier property has been specified in the configuration for this filter
and the event source is an identifier that matches exactly the specified EPC
identifier.
■
An EPC String has been specified in the configuration for this filter and the
event source is a String that matches exactly the specified EPC String
■
A Mask property has been specified in the configuration for this filter and the
event source is an identifier that matches the specified Mask’s identity URI
pattern.

URI, then it is treated as a String and the event’s source
must be a String that matches the EPC value
