Usage

From source file:com.streamsets.pipeline.lib.el.FileEL.java

@ElFunction(prefix = "file", name = "pathElement", description = "Returns element (directory or file name) from given index. On path /path/to/file.txt, 'path' have index 0, 'to' have index 1 and file.txt have index 2.")
public static String pathElement(@ElParam("filePath") String filePath, @ElParam("index") int index) {
    if (isEmpty(filePath)) {
        return null;
    }/*from  ww  w  .j  a va 2  s  .com*/

    // Array of elements of the path
    Path[] elements = Iterables.toArray(Paths.get(filePath), Path.class);

    // Accept negative index to count from the end of array
    if (index < 0) {
        // Using + as the number is negative, so the resulting operation is actually subtraction
        index = elements.length + index;
    }

    // Index have to be in range, otherwise return null (which will be very likely converted to empty string by EL engine)
    if (index < 0 || index >= elements.length) {
        return null;
    }

    return elements[index].toString();
