Poolboy is a very extensive process pool library in Erlang, it has many advantages and is easy to use, and can be seen in many projects. However, it also has some pits that need to be noticed when used. (The analysis of Poolboy is based on the 1.5.1 version)Worker creation cannot failA worker is created when Poolboy is initialized, or if the number of workers in the current process pool exceeds the default value. Let's take a look at the code for the new worker:new_worker(

be related to an entry that belongs to a specific structral object class. Although an entry can only belong to a single structural object class, it can belong to the auxiliary object classes.2. Inheritance of object classesA new object class can be defined with the parent class and additional added or modified attributes. All object classes are inherited from abstract object class and are called top inheritance. They can also be inherited from other object classes. Abstract object class defines

[Thinking in Java] note when writing constructor: Avoid calling other non-private methods, thinkingprivate I recently reviewed Thinking in Java and found an exciting knowledge vulnerability. I have to share it with you. In the previous article "Java class initialization process", the initialization sequence is incomplete. The actual initialization process is: However, we know that when the Sub class inherits the Sup of the parent class and overwrites
