Class FloatControl

java.lang.Object

eu.bandm.sig.adlib.FloatControl

public class FloatControl
extends Object

Data type for control signals with guaranteed initial values.

Many signals, in particular those implemented by subclasses of ClockedFloatSignalSource, attain a meaningful value only at the first clock event, that is, too late for initialization of the dataflow network.

Components that take parameters which can change dynamically are encouraged to:

1. declare a method to set the parameter value;
2. declare a constructor parameter of type FloatControl;
3. use the given initialValue for initialization;
4. route the signal value emitted by the given source to the setter method at each clock event, before computing their own value.

Note that the invocation of the setter method is not an event; implementations are explicitly allowed to do nothing if the new parameter value is identical to the old one.
