Learn about the Interpreter pattern from a conceptual level and how it is used in the framework.
- [Instructor] In the final behavior pattern … that we're going to talk about, … is one that has a very specific use case in Spring, … but it's not one that I've even ever implemented myself. … It's very, very seldom that you would use this. … So the interpreter pattern's primary use case … in the Spring framework, is through the … Spring Expression Language, and this might allude … to what this pattern is used for. … This pattern's use cases are as I mentioned, limited, … but most often if not always are used with user input. … The input is parsed and converted into specific commands, … or functions, and that parsing behavior is … what the interpreter is providing. … Expressions are deemed terminal or non-terminal … to determine if you need to do future parsing. … So it gives you this sort of tree structure where you're … parsing commands until you get to the end. … And if you've ever looked at how program languages … are parsed, this is sort of the same pattern, … only applied to a system instead of a programming language. …
