After Contronoller is activated, asp.net mvc gets the name of the target action based on the current request context, and then parses the corresponding method and executes it. In the execution of the whole action method, the analysis of model metadata is a very important link. asp.net MVC model actually view model, which represents the final binding to the view of the data, and the model metadata describes the model's data structure, as well as the model of the characteristics of each data membe

In MSF, some of the corresponding tool classes for accessing and maintaining metadata are provided, namely the metadata Storage Service. It helps store synchronization metadata for the provider, which means that copies of the metadata cannot be stored in other ways. The Metadata Storage service uses lightweight databases that take up small amounts of memory and disk space, which can be redistributed with the provider and are safe and reliable. The API provided by it separates the metadata store

the table by column.The column size of the BLOB type and text type is variable and can be very large. To improve the performance of storage in queries, these databases automaticallyThese types of columns are stored separately from the other columns in the table. If you make a query that does not contain a BLOB type and text type, you canMore efficient access to other columns has improved query performance.3. resolving metadata splitting columns : Creating association TablesConclusion : Don't le

A metadata label is a special kind of tag that is useful in code to provide the compiler with information on how to compile the program.In fact, these tags are not compiled into the generated SWF file, but simply tell the compiler how to generate the SWF file. The list of META tags in Flex is as follows: label Description [Arrayelementtype ("ElementType")] All allowed data types are defined in the array.

Meta-Class 1. Class is also an objectIn most programming languages, a class is a set of code snippets that describe how to generate an object. This is still true in Python:>>> class ObjectCreator(object):… pass…>>> my_object = ObjectCreator()>>> print my_object0x8974f2c>However, the classes in Python are far more than that. class is also an object. Yes, yes, that's the object. As long as you use the keyword Class,python The interpreter will create an

The meta-object SystemMeta-object provides Signal/slot, run-time type information, and dynamic property systems for inter-class communication.The use of Meta-object is based on the following three points: Qobject provides a common base class that can use MetaObject. By adding Q_object macros to the declaration of the class, you can turn on the metaobject of the class such as Signal/slot, dynami

Goto: meta name meaning: What is META? Meta is actually an auxiliary tag in the head area of the HTML language. In almost all of the pages, we can see similar to the following HTML code: Some people say, this code seems dispensable, not much practical effect!

Brief introductionIn the lookup W3school, the first sentence of "meta-data" Let me start the Google trip. And then very smoothly in the English version of the W3school found the desired results.

So here's an English version of W3school's explanation. ） The It is

Preface: Bishi in the open Source Library to do the program, but the source looked very faint (at that time the tutor told me this is the template meta-programming, you can not care too much), recently built the wheel when I want to learn STL source code, but it is the same feeling, roughly understand what he does to do, but do not know the mechanism inside. So began to learn "C + + template meta-programmin

"""Metaclass Effect:1) Creation of interception classes2) Modify the class3) return the modified class""""""Why use the Metaclass class instead of the function?Since __metaclass__ can accept any callable object, why use a class, because it is obviously more complex to use the class? There are several reasons for this:1) intentions will be clearer. When you read Upperattrmetaclass (type), you know what's going to happen next.2) You can use OOP programming. A
