实施用于基准化的SolutionIO接口 [英] Implementing a SolutionIO Interface for Benchmarking

问题描述

我正在尝试在项目中实现基准配置，无论我做什么，我似乎都遇到了某种错误.从文档中读了几遍之后，我发现我需要实现一个SolutionIO接口来读取输入并将其变成解决方案.

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.

这是我没有求解器的配置:

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>

我遇到的错误是在<problemIOClass>标记处(请参阅文章结尾).

The error I'm getting is at the <problemIOClass> tag (see end of post).

这是我的CustomBenchmarkIO(Custom SolutionIO):

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);
}

在这里，我有一个实现该接口的类:

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) {

}

}

我尝试使用类和接口，但是仍然遇到相同的错误.

I have tried using the class and the interface, but I still get the same error.

我发布此问题是因为我不知道自己没有尝试过什么，因为我不知道实现基准的所有可能方式.

I'm posting this question because I don't know what I haven't tried, as I don't know all the possible ways of implementing a benchmark.

推荐答案

您需要从optaplanner本身实现一个称为

You need to implement an interface from optaplanner itself, called SolutionFileIO: you don't need to define your own interface. It's in the jar optaplanner-persistence-common these days.

这篇关于实施用于基准化的SolutionIO接口的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
