Package org.moeaframework.problem

Class PropertiesProblems

java.lang.Object
org.moeaframework.core.spi.ProblemProvider
org.moeaframework.problem.PropertiesProblems
public class PropertiesProblems extends ProblemProvider
Legacy problem provider that loads problems defined in "moeaframework.properties". For example, we could add the following to the properties file: 
   org.moeaframework.problem.TestLZ1.class = org.moeaframework.problem.LZ.LZ1
   org.moeaframework.problem.TestLZ1.referenceSet = ./pf/LZ09_F1.pf
And then instantiate the problem with: 
 
   ProblemFactory.getInstance().getProblem("TestLZ1");
Defining problems this way is no longer recommended. Instead, we recommend using a RegisteredProblemProvider to register new problems with this framework.
