Details

Discover the power of OpenRewrite, an open-source framework for automated code transformation. This talk will delve into its inner workings, exploring how it converts source code into Lossless Semantic Trees (LSTs), enabling precise and efficient code analysis and modification.

We'll also explore the world of "recipes"—reusable, composable code transformation templates that simplify complex code refactoring tasks. Learn how to harness the flexibility of OpenRewrite's recipe system to automate custom code transformations, streamline your development workflow, and improve code quality.

Whether you're a seasoned developer or just starting, this talk will provide a comprehensive introduction to OpenRewrite and its capabilities, empowering you to unlock the full potential of automated code transformation.

Speaker: Tyler Van Gorder

Our speaker is the co-organizer of this meetup group. He is a seasoned Software leader with deep expertise in Platform Engineering and Enterprise software design and development. He has extensive experience with Java and loves sharing this knowledge with our community.

Portland Java User Group

Join us for the PDX JUG July Meetup where we will dive into the world of Structured Concurrency. Structured Concurrency is a preview feature in Java 21 and will simplify the common scatter-gather kind of pattern.

Tyler Van Gorder is our speaker, he has previously spoken about Virtual Threads in Java, and Structured Concurrency is a great complement to Virtual threads. In Tyler's words:

"Simplify concurrent programming by introducing an API for structured concurrency. Structured concurrency treats groups of related tasks running in different threads as a single unit of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability."

We will briefly recap how virtual threads work and then explore how related tasks can be grouped as a single unit of work. We will cover the different shutdown strategies and examine how the programming model compares to similar functionality using a reactive framework."

Don't miss this opportunity to network with fellow Java enthusiasts, share your experiences, and learn from each other. Whether you are interested in web development, software development, or JVM languages, this meetup is open to anyone who is passionate about Java.
