<div class="block"><code>Wire</code> property key (named <code>wireadmin.filter</code>) specifying a
filter used to control the delivery rate of data between the Producer and
the Consumer service.
<p>
This property should contain a filter as described in the <code>Filter</code>
class. The filter can be used to specify when an updated value from the
Producer service should be delivered to the Consumer service. In many
cases the Consumer service does not need to receive the data with the
same rate that the Producer service can generate data. This property can
be used to control the delivery rate.
<p>
The filter can use a number of pre-defined attributes that can be used to
control the delivery of new data values. If the filter produces a match
upon the wire filter attributes, the Consumer service should be notifed
of the updated data value.
