This process controls the rate of flow of traffic from its input to output channels.

Description
RegulateInt produces a constant rate of output flow, regardless of
the rate of its input.
At the end of each time period, it outputs the last object input during that period.
If nothing comes in, the previous output will be repeated
(note: this is defined to be zero if nothing has ever arrived).
If the input flow is greater than the required output flow, data will be discarded.
The interval (in msecs) defining the output flow rate is given by a constructor argument.
This can be changed at any time by sending a new interval (as a Long)
down its reset channel.
Channel Protocols
Input Channels |
in |
int |
The input stream.
|
reset |
java.lang.Long |
This resets the time interval between outputs (milliseconds).
|
Output Channels |
out |
int |
This carries samples from the input data, sampled at the
defined rate.

Implementation

here (for the implementation
of
Regulate
– which is the same apart from regulating
Object,
rather than
int, traffic).
