[JBoss JIRA] (DROOLS-1422) Make AccumulateFunction simpler and more powerful

by Geoffrey De Smet (JIRA)

Geoffrey De Smet created DROOLS-1422: ---------------------------------------- Summary: Make AccumulateFunction simpler and more powerful Key: DROOLS-1422 URL: https://issues.jboss.org/browse/DROOLS-1422 Project: Drools Issue Type: Feature Request Components: core engine Reporter: Geoffrey De Smet Assignee: Mario Fusco * Replace the AccumulateFunction interface with the AccumulateFunction2 interface: ** All core runtime code uses the AccumulateFunction2 interface. ** Deprecate AccumulateFunction and use a bridge class at DRL compilation time so old implementations still work because they are bridged into the new interface * Changes of the AccumulateFunction2: ** Methods no longer throw checked exceptions (no "throws Exception"), so drools doesn't have to catch them. This might improve performance. ** Remove "Serializable context". The class itself contains the state. *** Remove method createContext() *** Replace method init(Serializeble) with constructor call (no-args normally) *** Remove parameter Serializable from accumulate(value), reserve(value) and getResult() methods *** This might improve performance. ** It should Serializable, but doesn't have to Externalizable. Removes methods writeExternal() and readExternal() in the user implementation. * Interface ReversableAccumulateFunction2 extends AccumulateFunction2 ** Only ReversableAccumulateFunction2 has method reverse(value) ** Remove method supportsReverse(): the custom accumulate is reverseable if it also implements this interface * Opportunities ** construction parameters. For example: fixed average for standard deviation (very useful for OptaPlanner) ** Multi-argument accumulates, for example in DRL: `$total : standardDeviation($groupBy, $weight)` {code} public class SumAccumulateFunction implements ReversableAccumulateFunction2<Integer, Integer> { public int total; public SumAccumulateFunction() { total = 0; } public void accumulate(Integer value) { total += value; } public void reverse(Integer value) { total -= value; } public Integer getResult() { return total; } } {code} {code} public class AverageAccumulateFunction implements ReversableAccumulateFunction2<Integer, Double> { public int total; public int count; public AverageAccumulateFunction() { total = 0; count = 0; } public void accumulate(Integer value) { total += value; count++; } public void reverse(Integer value) { total -= value; count--; } public Double getResult() { return (double) total / count; } } {code} {code} public class StdDeviationAccumulateFunction implements ReversableAccumulateFunction2<Integer, Double> { public final double average; public double variance; public StdDeviationAccumulateFunction(double average) { this.average = average; variance = 0; } public void accumulate(double value) { variance += (value - average)²; // TODO } public void reverse(double value) { variance -= (value - average)²; // TODO } public Double getResult() { return Math.sqrt(variance); } } {code} -- This message was sent by Atlassian JIRA (v7.2.3#72005)
