Java Source Code / Java Documentation » Science » Cougaar12_4 » org.cougaar.qos.qrs   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.cougaar.qos.qrs.DataFormula       org.cougaar.qos.qrs.PollingIntegral All known Subclasses:   org.cougaar.qos.qrs.SingleKeyPollingIntegral, PollingIntegral abstract class PollingIntegral extends DataFormula (Code) This a 'rate-ifier' abstraction. It's designed to accumulate calculated instantanteous data so that a periodic poller can supply a rate to the client. The period is supplied as an argument. For now the assumption is that raw values are doubles. Instantiate subclasses must provide two methods: configureDependencies(), to set up any dependencies on other formulas, and computeValueFromDependencies, which should calculate a new value given a collection of dependency values. A useful extension is SingleKeyPollingIntegral.java, a PollingIntegral which relies on a single DataFeed value.
