Utility Classes¶
Utility classes of other languages can contain reusable methods that can be interesting for your own languages. They often have the suffix Util or Helper. Classes ending with Manager also can have those methods. You can access them through static getInstance methods or, if they are core components, through jetbrains.mps.project.Project#getComponent. To find new methods, search for nodes named [TOPIC]+ [suffix] e.g. "UI" + "Util" becomes UIUtil. If you work closely with MPS languages, search their runtime models for useful methods. For example, jetbrains.mps.ide.httpsupport.runtime.base contains a utility class HttpSupportUtil ⧉ that helps with the HTTP Support plugins.
