Detailed Description

template<typename T>
class sensesp::RepeatConstantRate< T >

Repeat transform that emits the last value at a constant interval.

The last value is emitted at a constant interval, regardless of whether the value has changed or not. If the value age exceeds max_age, expired_value is emitted.

This is particularly useful for outputs that expect a value at a constant rate such as NMEA 2000.
