LCOV formatting

Each class provided by this library has a dedicated toString() method returning the corresponding data formatted as LCOV string. All you have to do is to create the adequate structure using these different classes, and to export the final result:

import io.belin.lcov.FunctionCoverage;
import io.belin.lcov.LineCoverage;
import io.belin.lcov.LineData;
import io.belin.lcov.Report;
import io.belin.lcov.SourceFile;
import java.nio.file.Path;
import java.util.List;

class Program {
  public static void main(String... args) {
    var sourceFile = new SourceFile(Path.of("/home/cedx/lcov.java/fixture.java"));
    sourceFile.functions = new FunctionCoverage(1, 1);
    sourceFile.lines = new LineCoverage(2, 2, List.of(
      new LineData(6, 2, "PF4Rz2r7RTliO9u6bZ7h6g"),
      new LineData(7, 2, "yGMB6FhEEAd8OyASe3Ni1w")
    ));

    var report = new Report("Example", List.of(sourceFile));
    System.out.println(report);
  }
}

The Report.toString() method will return a LCOV report formatted like this:

TN:Example
SF:/home/cedx/lcov.java/fixture.java
FNF:1
FNH:1
DA:6,2,PF4Rz2r7RTliO9u6bZ7h6g
DA:7,2,yGMB6FhEEAd8OyASe3Ni1w
LF:2
LH:2
