position per billion. 6.7 State Machine Design A state machine, also known as a finite state machine (FSM), is a behavioral model that consists of a set of well-defined states, transition rules between states, and an initial state. It transitions from one state to another based on the current state and input events. The figure below is the state machine design of a transaction order in a subdomain design that it takes over. As you can see in the figure, there are a total of states, and the transition between each state is triggered by a specific event.
I often see colleagues who have been working belgium email list for several years still using if else or changing the case of writing state machines. This is incorrect and makes the implementation complex and prone to problems. You can even use String to define it directly in the account domain model instead of encapsulating the state pattern in a separate class.Another option is to directly call the domain model to update the state instead of running it through events. Due to space limitations, exact examples will not be given here. If you are interested, you can look it up on the Internet.
6.8 Log Specifications As long as you have been writing code in a company, you must have printed logs, but it is often found that the logs printed by some engineers who have worked for many years are also messy. I once took over a job that had been online for more than a year in one of the leading Internet companies. In the end, engineers could only rework and modify relevant tasks. We need to understand what the log is used for. Only if we first understand the purpose of doing things, can we do things better.
