Walkthrough

The changes introduce a new difference function in the N3Store class, which computes the differences between two graph indices. It modifies the equality method to utilize this function when comparing instances with the same entity index. Additionally, a series of tests are added to validate the functionality of the difference and union methods, ensuring correct behavior in various scenarios.

🐇 In the garden where graphs play,
A difference found brightens the day.
With quads that dance and sizes that shift,
New methods added, a wonderful gift!
So hop along, let’s test and explore,
For every change opens a new door! 🌼

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>, please review it.
  -- 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  -- @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.

48-78: Well-implemented 'difference' function for computing graph differences

The newly introduced difference function accurately computes the difference between two _graphs indices, handling nested structures recursively and correctly returning false when there are no differences. This addition enhances the store's capability to efficiently determine differences between datasets.

931-939: Efficient utilization of 'difference' function in dataset difference computation

In the difference method, the implementation effectively uses the new difference function when the other N3Store shares the same _entityIndex. This approach optimizes the performance by directly computing the differences in the internal _graphs representation, rather than iterating over each quad. The fallback to filtering quads when _entityIndex differs ensures compatibility with other datasets.
