Class LinesStream

java.lang.Object

jenkins.util.io.LinesStream

All Implemented Interfaces:

Closeable, AutoCloseable, Iterable<String>

Deprecated.

use Files.lines(Path)

@Deprecated
 @CleanupObligation
public class LinesStream
extends Object
implements Closeable, Iterable<String>

Represents a stream over the lines of a text file.

Although LinesStream implements Iterable, it is intended to be first used to initialize a resource in a try-with-resources statement and then iterated, as in:

  try (LinesStream stream = new LinesStream(...)) {
      for (String line : stream) {
          ...
      }
  }
 

This pattern ensures that the underlying file handle is closed properly.

Like DirectoryStream, LinesStream supports creating at most one Iterator. Invoking iterator() to obtain a second or subsequent Iterator throws IllegalStateException.
