Equal to method Message Information that is used in the output application to provide a journal event. Mdc The MDC (old name: Threadcontext.properties) is part of the Union event. This mode supports compatibility but is equivalent to property. Method Use the name of the method used to produce a journal.Warning : The location information of the production caller is slow. Try to avoid it, unless the speed is not a problem.

Failed", ex); } }Else{Log.error ("specified car type {} does not exist", type); }returnCar }}As you can see from the code above, the factory scans all the car vehicle annotations (each car declares its type in the note and can be used as an alias for that car) and then establishes a class original mapping of the car alias to the specific car. At this point the static method of the factory can instantiate the corresponding car according to the target alias.All the code in this article is avai

A small, automated version of the tool was implemented in Python. This "Automatic Version" is a bit virtual, just simply copy the configuration file under the Debug directory to the specified directory, copy the generated files under release to the same designation, filter out the unwanted folders (. svn), and then add several specific files to the specified directory.This is my first Python applet.Here's a look at the implementation of the Code.First

This is useful if you have several associated scripts.Run the following command to display all the command line tokens for the Py2exe command.Python mysetup.py py2exe--helpIv.

reading. In other words, if you read a lot of threads and few write threads, you can be optimistic that there is very little chance of writing and reading occurring at the same time, so it is not pessimistic to use a full read lock, and the program can see if the data is read, whether it is being changed by the write thread, and then take the next steps. Use the Condition:condition interface to match the lock. Calling condition's await () will cause the thread to enter the condition waiting s

Reentrantreadwritelock.writelock calls the Lock () method, which means that a write lock can be obtained without any read or write lockValidate (): Verify that the stamp was not acquired by another exclusive lock, and if so, returns False if the stamp is 0 and returns false conditionThe condition interface is used with Lock, and the most basic usage is to achieve the function of the Wait (), notify (), Notifyall () method of Object.signal (): To notify a thread in the Wait collection, you can c

变量或者函数前，以标示变量或者函数的定义在别的文件中，提示编译器遇到此变量和函数时在其他模块中寻找其定义。此外extern也可用来进行链接指定。typedef char Line[81]; int (*PF)(int , int);typedef int (*PF) (int, int);Why do I add extern "C" when I call a function compiled by the C compiler in C + +?C+ supports function overloading, while C does not, and functions are c+ compiled and C-compiled with different names in the library. For example, void foo (int a,int b), C may be _foo, and c+ is foo_int_int.At this point the C function will need to use the extern "C" f

Registration Channel: TcpChannel channel = new TcpChannel (); ChannelServices.RegisterChannel (channel); Note When a client instantiates a channel, it is the default constructor that is called, that is, the port number is not passed. In fact, this port number is integral, except that its designation is placed behind it as par

, in this method soap ( Simple Object Access Protocol ) messages to the content of the message to provide a consistent representation. In addition, when SOA is truly used for enterprise-class applications, additional factors such as message security, reliable transmission, transactional support, and so on, need to be considered. To achieve a truly cross-platform operation, the interoperability of these features requires an open standard. In this regard, some major IT vendors such as Microsoft, I

[0] It should be noted that the URL mapping table inside the Tornado and Django is the same order, that is, the URL in order from top to bottom matching, as long as the match to the immediate end, no longer match, and the URL of the domain name and the generi

function is the function that an instance of a class will call, and whenever we invoke obj = Foo () to instantiate a class, we call __new__ () first. Then call the __init__ () function to initialize the instance. __INIT__ () executed after __new__ () execution, The class also has an attribute __metaclass__, which is used to indicate who created the class by whom it was instantiated, so we can view the process of class creation by setting a derived class of type class for __metaclass__.

the "ABC" object, also called Make a reference to the "ABC" object. 4. String objects can be concatenated by "+". A new string is generated after concatenation. It can also be concatenated by concat (), which is explained later. 6. The Java runtime maintains a string pool, Javadoc translation is very vague "string buffer". The string pool is used to hold the various strings produced in the runtime, and the contents of the strings in the pool are not duplicated. The normal object does not exis

priority of a process. if multiple processes are in the executable state at the same time, there is nothing to worry about when there is a higher priority. How can we determine the priority of a process? You can use either of the following methods: User program designation and dynamic adjustment by the kernel scheduler. (As mentioned below) The Linux kernel divides processes into common and real-time processes. Real-time processes have higher priori

dealing with consumer audio output. The audio may not have any output whatsoever, or it may be mono, stereo, or surround sound.This may have some potential logic definitions without any output of 0, mono as 1, stereo 2, and the value is provided by the number of channels.So what value do you give Dolby 5.1 surround stereo.On the one hand, it has 6 channel outputs, but on the other hand, only 5 channels are full-bandwidth channels (hence the 5.1 designation
