Python metadata usage instance and python metadata instance
The examples in this article describe the usage of meta-classes in python and share them with you for your reference. The specific method is analyzed as follows:
1. metaclass is a class used to create a class.
2.Type (object): returns the type of an object, which is the same as the value of object. _ class _., Type (name, bases, dict): Creates a ne

I deployed a WCF Service on the server and mapped it to the Internet. When an Internet client references the service, the metadata address host name is always the computer name of the server. Because the client is on the Internet of the server, therefore, the client cannot identify the computer name of the server.
For example, my published service address is http: // Internet address: Port Number/service name. SVC. The

Pentaho report Designer (PRD) can support a variety of data source input methods. Pentaho Metadata Editor as a member of the home platform, it should be a cinch. Right.

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization.
The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling
The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru
