8. Serialization    coderanch.com

Put simply, serialization is the process of converting an entire Java object and all it's data and attributes into a serial form: a form that can be transmitted over a stream. Typically, Java objects are serialized and passed around using ObjectInput/Output Streams. The serialization is done automatically as part of the writeObject() method. Serialized Java objects can be deserialized as well. ...

29. Serializable    coderanch.com

In basic terms, serialiazation means converting a java Object into a series of bytes, which can be persisted and/or transported over the wire to have the Object reconstructed later on. JDK provides the easy way of serializing a Java object and that is implementing the java.io.Serializable interface. By implemetning the interface, you are approving jvm that this object can be persisted. ...

30. How do I serialize?    coderanch.com

The fact that it is not serializable should give you pause. Maybe passing it to an EJB method is not the best approach. In fact, EJBs should not concern themselves with implementation details like whether some piece of data goes to a servlet or to /dev/null. It should just return the business data, and let the client facade handle the rest. ...

33. serialization    coderanch.com

Serializing in Java has a specific meaning used with ObjectOutputStream and such. As a generic term, serialize means convert an in-memory structure into another format that can be sent between software components, usually into bytes that can be sent one at a time - serially - over a wire. RMI certainly counts as an example of that. Other examples include converting ...

37. Serialization    coderanch.com

Serializable is an interface. All the compiler does is to check that the class implements all methods declared in that interface. Since there are none, every class passes this test. Using Serializable is more like a promise by you -the author of the class- that the class is actually serializable, i.e. that it doesn't contain references to objects that can't be ...

41. Serialization    coderanch.com

Serialization is preferred when you want to persist the state of the object. That means saving the state of the object into a permanent storage. Say, into a file in the disk. State of the Object means the values of instance variables of the object you are serializing excluding the variables which are declared as 'transient'. Serialization - process of storing ...

54. Serializable    coderanch.com

Interesting... Let me see if I got this right. When you serialize an object, you serialize the object's non-static class-level properties? The object itself is just a pile of property data in memory. Methods are not stored in the object. That's why an object can be serialized, because its just property data? For instance, when a reference variable is declared as ...

Originally posted by Dan Pollitt: Implementing the java.io.Serializable interface but adding no additional methods means you are stating that the object can be serialized by Java's default mechanism.

56. why Serialization has no methods    coderanch.com

Implementing Serializable is just how you tell Java that it's OK to serialize a class. This kind of empty interface is called a "marker interface" and there are a handful of them in the Java APIs. Besides Serializable, Externalizable, and Remote, there's java.lang.Cloneable, which tells the default implementation of clone() that it's OK for it to be invoked.

59. Serializable    coderanch.com

Hi, 'Serializable' is a marker interface. A marker interface is one that has no methods. By implimenting a marker interface, you're telling the JRE that your class has specific properties. For example, if your class implements Serializable, then the JRE knows that it doesn't have to do anything special to serialize it. (convert an object of your class into a byte ...

Indeed, if a parent class implements Serializable, the subclass is-a serializable object. But remember, Serializable is as much a commitment as it is an implementable interface.

74. Serialization    coderanch.com

There is really no performance hit if you implement Serializable, but you should implement it with care. Not everything should be Serializable.

Also, you probably don't want to make everything Serializable because ...

Serialization refers to the idea that any object can be written (with its current state) to a file, a socket...any stream.
