Introduction

In this page you can find the example usage for org.apache.commons.lang SerializationUtils serialize.

Prototype

public static void serialize(Serializable obj, OutputStream outputStream) 

Source Link

Document

Serializes an Object to the specified stream.

The stream will be closed once the object is written.

Usage
