serializable interface

Usually we are in Java memory object, is unable to do IO operation or network communication, because in the IO operation or network communication, people do not know what the memory object is a thing, so the object must be expressed in some way,

I. The concept of serialization and deserialization　　The process of converting an object to a sequence of bytes is called serialization of an object .The process of reverting a sequence of bytes to an object is called deserialization of the object

Hibernate annotations map three main methods of joint primary keys, hibernate primary keys During project creation today, an intermediate table has no primary key and no components are added when an object is created. The following error is returned:

1. What is serialization and deserializationSerialization (serialization) is a process of describing objects in a sequence of bytes, and deserializing deserialization is a process of re-building these bytes into an object.2. What situations require

Design Mode-command modeOverview In software development, we often need to send requests (call one or some methods) to some objects, but we do not know who the request receiver is, we do not know which operation is requested. At this time, we

IO stream in java and javaIO stream Stream: java stream is a class developed by Sun for file operations and data transmission, but it is called a stream. all opened streams must be closed because the opened streams consume resources and are insecure.

Two ways to implement serialization in Java Serializable interface and externalizable interfaceThe serialization of an object is the writing of an object to the output stream.Deserialization is the reading of an object from an input stream.The

See the code today see a JavaBean implementation of the Serializable interface, which is the identity class interface, there is no method or constant, find the following blog deliberately recorded.Reprint: http://www.cnblogs.com/gw811/archive/2012/10

Java serialization is the encoding of an object into a byte stream, and deserialization converts the byte stream encoding into an object. Serialization is a method of implementing persistent storage in Java and provides a line-level object

1. What is the serializable interface?http://en.wikipedia.org/wiki/serializationThe serialization of a class is implemented through the class implementation of the Java.io.Serializable interface. Classes that do not implement this interface will not

Serialization (serialization) is also called serializing, which allows a program to write a complete object into a byte stream. With crossdress (deserialization), you can read a complete object stored in a byte stream.Serialization can convert Java

What does serialization do?This is simply to preserve the state of various objects in memory (i.e., instance variables, not methods), and to read the saved object state again. Although you can save object states in a variety of ways, Java provides

Java provides a mechanism called serialization, which persists Java objects in an ordered format or byte sequence, containing the object's data, the object's type, and the data type stored in the object. So, if we have serialized an object, it can

This process can also be done over the network by first creating an object on the Windows machine, serializing it, and then sending it over the network to a UNIX machine, where it can be correctly reassembled. One of them, like RMI, sockets, JMS,

In writing Javame program, we often need to save some data to the phone, but also often want to be able to save objects to the phone inside, but javame there is no reflection mechanism, there is no Java.io.Serializable interface, so there is no

1. The principle of level two caching As described earlier, the level two cache in MyBatis is a mapper cache, and it is noteworthy that different mapper have a level two cache, that is to say, the two-level cache between different mapper is not

Hibernate Federated Primary Key mapping rules: First: Primary keys and attributes in a class 1. Configuration files Note: The primary key configuration label for the Federated primary Key is represented by . 2

As you can see, the default serialization mechanism is not difficult to manipulate. But what if there are special requirements? We may have special security issues, we don't want to serialize a part of the object, or a child object does not have to

The goal of object serialization is to either save the object on disk or transfer it over the network. The implementation mechanism is to allow the object to be transformed into a platform-independent binary stream.The serialization mechanism for
