first, the new old class of Python object-oriented 1) New Class (recommended): When defining a class, the class is followed by the base class (object) in parentheses. In python3.x, if the parent class is not specified, object is used as the base class by default, and in python2.x, if no parent class is specified, object is not used as the base class. 2) Legacy Class (classic Class): When you define a class, the class does not inherit the object class

Test the legacy code
In most cases, it is difficult to test the code. Because many codes cannot inject parameters, there is an unrestricted isolation framework TypeMock for you to use, unfortunately, this software is a paid isolation framework and has a 15-day free use right. If you can solve your existing problems, I don't think the cost is too much. Official download of TypeMock: http://www.typemock.com /. Next let's take a look at how TypeMock is u

two regions meets the above formula, the region is considered to be the removal of objects, and the background model corresponding to the region needs to be further updated; otherwise, it is the legacy of objects, the background model corresponding to the region is not updated. Why is the criterion valid? In practice, the background tends to be the same in the scenario, that is, the adjacent areas in the same scenario are similar (especially in indoo

map method, we first select the attributes of the class, and then map the selected Attribute list to a database table.
We add a new unit test in our test program to test whether Entity Framework code first persists this class instance to two tables.

Legacy problems
The first two articles mentioned some features that are not supported during retrieval. For example, if syanz cannot be searched by Sun Yanzi's name, today, we have corrected the word segmentation.Solution
The name field is converted into two types: full spelling and simple spelling. For example, Sun Yanzi, the result of PinYin conversion is sunyanzi, syz, the conversion result is then split into n-grams in the forward and backward dir
concrete implementation class, and the Create method of the implementation class still uses the factory method pattern. Unfortunately currently Enovia kernel JDK is still 1.6, I can not use switch (String), only use ugly if...else ... To solve it.I sent the refactoring program document, implementation code and test report to the PLM project manager in Europe for review, and I didn't expect it to be approved because I had previously suggested some decoupling and performance improvements to the p
