Interface ParameterValue
-
public interface ParameterValue
Represents a parameter and its value.This used for field comparison algorithms and decision tree node comparison functions.
Code Sample
public class CustomMatchingUserServiceSample implements UserService<TableViewEntitySelection> { public void setupDisplay( UserServiceSetupDisplayContext<TableViewEntitySelection> context, UserServiceDisplayConfigurator configurator) { Session session = context.getSession(); AdaptationTable table = context.getEntitySelection().getTable(); MatchingOperations matchingOperations = OperationsFactory .getMatchingOperations(session); // execute evaluate matching between two records that using a // matching policy with the code 'matchingPolicyCode' Adaptation record1 = table .lookupAdaptationByPrimaryKey(PrimaryKey.parseString("1")); Adaptation record2 = table .lookupAdaptationByPrimaryKey(PrimaryKey.parseString("2")); EvaluateMatchingResult evaluateMatchingResult = matchingOperations .evaluateMatching(record1, record2, "matchingPolicyCode"); // gets and traverses decision tree nodes in the decision // from the root node to the last node Iterator<DecisionNode> decisionNodes = evaluationMatchingResult .getDecisionNodes().iterator(); if (decisionNodes.hasNext()) { DecisionNode rootNode = decisionNodes.next(); List<ParameterValue> parameters = rootNode .getComparisonFunctionParameters(); Integer minimumScore = parameters .stream() .filter(p -> p.getName().equals("minimumScore")) .findFirst() .map(p -> p.getValue(p.getValueType())); } } }
