Walkthrough

The changes involve significant updates to the ExpressionUtil class, enhancing its ability to parse Expression Language (EL) expressions. New overloaded parse methods have been added to accommodate different input types, and the internal logic for expression evaluation has been refactored for better organization. Additionally, a new test class, ExpressionUtilTest, has been introduced to validate the functionalities of the ExpressionUtil, ensuring comprehensive coverage of various parsing scenarios.

Poem

In fields of code, where rabbits play,
New methods hop in, brightening the day.
Parsing with ease, like a breeze in the sun,
Each test a burrow, where all can run.
With every change, our joy does swell,
In the world of Spring, all is well! 🐇✨

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
