Java AccumulatorPathVisitor-class And Method Code Example
Here is an example of how to use the AccumulatorPathVisitor class from the org.apache.commons.io package in Java:
import java.io.File;
import org.apache.commons.io.FileUtils;
import org.apache.commons.io.filefilter.TrueFileFilter;
import org.apache.commons.io.filefilter.IOFileFilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;
import org.apache.commons.io.comparator.PathFileComparator;
import org.apache.commons.io.comparator.SizeFileComparator;
import org.apache.commons.io.comparator.AccumulatorPathVisitor;
public class AccumulatorPathVisitorExample {
public static void main(String[] args) {
// Define the directory to search in
File directory = new File("/path/to/directory");
// Define the file filter to use
IOFileFilter fileFilter = new WildcardFileFilter("*.txt");
// Define the path comparator to use
PathFileComparator pathComparator = new PathFileComparator();
// Define the size comparator to use
SizeFileComparator sizeComparator = new SizeFileComparator();
// Create a new AccumulatorPathVisitor instance
AccumulatorPathVisitor visitor = new AccumulatorPathVisitor(fileFilter, pathComparator, sizeComparator);
// Visit all files in the directory
FileUtils.visitFileTree(directory, visitor);
// Get the accumulated files
List<File> files = visitor.getFiles();
// Do something with the accumulated files
for (File file : files) {
System.out.println(file.getName());
}
}
}
In this example, we are using the AccumulatorPathVisitor class to find all the files in a specific directory that match a certain file filter, in this case, files that end with ".txt".
