Methods
Properties
timestamp
timestamp of the value change
getTimedValueTimestamp :: MonadIO m => TimedValue -> m Word64 Source #
Get the value of the “timestamp” field.
When overloading is enabled, this is equivalent to
get timedValue #timestamp
setTimedValueTimestamp :: MonadIO m => TimedValue -> Word64 -> m () Source #
Set the value of the “timestamp” field.
When overloading is enabled, this is equivalent to
settimedValue [ #timestamp:=value ]
value
the corresponding value
getTimedValueValue :: MonadIO m => TimedValue -> m Double Source #
Get the value of the “value” field.
When overloading is enabled, this is equivalent to
get timedValue #value
setTimedValueValue :: MonadIO m => TimedValue -> Double -> m () Source #
Set the value of the “value” field.
When overloading is enabled, this is equivalent to
settimedValue [ #value:=value ]
