Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java

package okhttp3.sample;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.security.GeneralSecurityException;
import java.security.KeyStore;
import java.security.SecureRandom;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;

  /** Returns -1 if unset. */
  val headerTableSize: Int
    get() {
      val bit = 1 shl HEADER_TABLE_SIZE
      return if (bit and set != 0) values[HEADER_TABLE_SIZE] else -1
    }

  val initialWindowSize: Int
    get() {
      val bit = 1 shl INITIAL_WINDOW_SIZE

 * it easy to get sample values to use in such tests.
 *
 * This class is pretty fast and loose with default values: it attempts to provide values that are
 * well-formed, but doesn't guarantee values are internally consistent. Callers must take care to
 * configure the factory when sample values impact the correctness of the test.
