I'm trying to implement a benchmark configuration in my project, and whatever I do, I seem to encounter some sort of error. After a few reads from the Documentation I discovered that I need to implement a SolutionIO interface to read the input and make it into a solution.
This is my configuration without the solver:
<benchmarkDirectory>local/data/nurserostering/folder</benchmarkDirectory> <inheritedSolverBenchmark> <problemBenchmarks> ----> <problemIOClass>org.optaplanner.examples.nurserostering.persistence.CustomBenchmarkIO</problemIOClass> <----- <inputSolutionFile>data/nurserostering/import/importTest/Input0.xml</inputSolutionFile> </problemBenchmarks> The error I'm getting is at the <problemIOClass> tag (see end of post).
This is my CustomBenchmarkIO(Custom SolutionIO):
package org.optaplanner.examples.nurserostering.persistence; import java.io.File; import org.optaplanner.core.api.domain.solution.Solution; public interface CustomProblemIOInterface { String getFileExtension(); Solution read(File inputSolutionFile); void write(Solution solution, File outputSolutionFile); } And here I have a class that implements that interface:
package org.optaplanner.examples.nurserostering.persistence; import java.io.File; import org.optaplanner.core.api.domain.solution.Solution; import org.optaplanner.persistence.common.api.domain.solution.SolutionFileIO; public class CustomBenchmarkIOClass implements CustomProblemIOInterface{ public String getInputFileExtension() { return null; } public String getOutputFileExtension() { // TODO Auto-generated method stub return null; } public Solution read(File inputSolutionFile) { return null; } public void write(Object solution, File outputSolutionFile) { } } I have tried using the class and the interface, but I still get the same error.
Here is the full error log:
