serializable class

When the serializable feature is used, if the class is updated (but must be compatible with the previously serialized Class Object), you can use the optionalfield feature to mark the newly added field. As for the serializable feature in class

We know that we can add the serializable attribute to serialize and deserialize objects. It is usually used to store and transmit objects. For example [Serializable]class ShoppingCartItem{public int productId;public decimal price;public int quantity;

Java.io.Serializable Analysis　　Java API Java.io.Serializable Interface Source code:1 public interface Serializable {2}The Java.io.Serializable class enables its serialization functionality by implementing the interface. A class that does not

Encountered this Java Serializable serialization of this interface, we may have the following problemsA, what's called serialization and deserializationb, the effect. Why do you want to implement this Serializable interface, which is why you want to

Java basics-serialization and java serialization 1. java serialization When two processes perform remote communication, they can send different types of data to each other. Regardless of the type of data, it is transmitted in binary sequence. The

The serialization runtime is associated with each serializable class using a version number called Serialversionuid, which is used during deserialization to verify that the sender and receiver of the serialized object have loaded a

Implementing java.io.Serializable This interface is for serialization, and Serialversionuid is used to indicate compatibility between different versions of the serialization class. If you modify this class, you want to modify this value.Otherwise,

We know that we can add the serializable attribute to serialize and deserialize objects. It is usually used to store and transmit objects. For example Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->[

1. Explanation of JAVA serialization in java api 1.6.0:Class to enable its serialization function by implementing the java. io. Serializable interface. Classes that do not implement this interface cannot be serialized or deserialized in any State.

The serialization mechanism for Java is to validate version consistency by judging the serialversionuid of the class at run time. When deserializing, the JVM compares the serialversionuid in the stream that is transmitted to the serialversionuid of

When writing a serializable class, MFC uses the pattern number you specify to develop a rough version control method. When writing data to a file, MFC uses patterns to mark instances of the class, and when the data is read, MFC compares the pattern

Streaming* The stream abstracts the external storage of data (usually objects ).* Streaming APIs are abstract-It provides interfaces for reading data from the storage and writing data to the storage, but does not care what the storage is-Defined in
