Apex Comments
Apex Comment Syntax
Apex comments use // and /* */ with ApexDoc for APIs.
Introduction to Apex Comments
Comments are essential in programming to explain code logic, make it readable, and maintainable. In Apex, comments can be single-line or multi-line, and there's also a way to generate documentation using ApexDoc.
Single-Line Comments
Single-line comments in Apex start with //
. Everything after these characters on the same line is considered a comment.
Multi-Line Comments
Multi-line comments begin with /*
and end with */
. This is useful for commenting out larger blocks of code or adding detailed explanations.
ApexDoc for API Documentation
ApexDoc is a tool used to generate documentation for your Apex classes. Similar to Javadoc, ApexDoc comments begin with /**
and are placed before classes, methods, or properties.
Best Practices for Using Comments in Apex
Effective commenting can greatly enhance code readability and maintainability. Follow these best practices:
- Use comments to explain why code exists, not what it does.
- Avoid redundant comments that state the obvious.
- Keep comments up-to-date with code changes.
- Use ApexDoc for public APIs to ensure comprehensive documentation.
