Today, we are studying that the client is an associated expression interface. Take a note.

& Nbsp; for this class chart, LZ simply introduces two points. <P> & nbsp; 1. The client is the associated expression interface, however, a syntax analyzer (grammerparser) is added in the middle, so it becomes the client associated syntax analyzer, And the syntax analyzer then associates with the expression interface. </P> <p> & nbsp; 2. Because we use reverse computing, non-terminator expressions do not have an aggregation line to the expression interface. Instead, they are replaced by two correlated lines. </P> <p> <br/> </P> <p> & nbsp; & nbsp; this is the end of the interpreter mode. You only need to know about it.

Therefore, if a design pattern cannot be understood at half past one, do not try to understand it.

Today, we are studying that the client is an associated expression interface. Take a note. For this class chart, LZ simply says two points.

1. The client is originally an associated expression interface. However, because a syntax analyzer (grammerparser) is added in the middle, the client is associated with the syntax analyzer, And the syntax analyzer is then associated with the expression interface.

2. Because we use reverse computing, non-terminator expressions do not have an aggregation line to the expression interface. Instead, they are replaced by two correlated lines.

This is the end of the interpreter mode. You only need to know about it. If you cannot understand it, you don't have to worry about it.

Learning the design model is sometimes the same as chasing girls. If you cannot catch up with it, it means the fate is not there. You have to give up when you give up. Maybe it's a fate someday, if you don't need to catch up with her, she will naturally be hooked up. Therefore, if a design pattern cannot be understood at half past one, do not try to understand it. The reason is that your accumulation is not enough, they are often beaten by the design model and have to pay their own medical fees.

LZ just wanted to say, why?

As of this article, LZ has explained all 24 design patterns, including good, bad, and wrong. However, lz is still very rewarding, and I am very grateful to the friends who support LZ. The design pattern series may have the last article. The content is naturally a Summary of the 24 design patterns. LZ is also preparing for this recently. Please keep your eyes open and look forward to it.

The end of a series does not mean that the learning path of LZ is over. As mentioned in the previous chapter, LZ has recently studied the Virtual Machine source code. In the following time, LZ may write some virtual machine-related content. If any yuanyou is interested in the virtual machine, you can continue to pay attention to LZ.

Thank you for watching. We will see you next time.
