Complete API documentation

Documentation should be complete, accurate, and follow Spring Framework conventions. Ensure your Javadocs include:

1. Clear and accurate descriptions that precisely explain behavior and purpose ```java /**
   • Returns a concise description of this {@code HandlerMethod}, which is used
   • in log and error messages.

   • The description should typically include the method signature of the

   • underlying handler method for clarity and debugging purposes. */ ```
2. Complete parameter documentation for all parameters, especially in interfaces ```java /**
   • Called before every retry attempt.
   • @param retryExecution the current retry execution context */ default void beforeRetry(RetryExecution retryExecution) { ```

3. Class-level Javadoc for all public classes and interfaces

4. Format standards:
   • Wrap Javadoc around 90 characters
   • Don’t end @param or @return descriptions with periods unless they contain sentences
   • Include @since tags for all new public methods
5. Contextual information about when and how to use the API: ```java /**
   • Create a builder with the method, URI, headers, cookies, attributes, and body of the given request.
   • @param other the request to copy the method, URI, headers, cookies, attributes, and body from
   • @return the created builder
   • @since 5.3 */ ```
6. Clear behavioral documentation for methods with special handling: ```java /**
   • Create a builder with the given method and given string base URI template.

   • The given URI template may contain URI variable placeholders that can be expanded using

   • the methods of the built request.
   • @param method the HTTP method (GET, POST, etc)
   • @param uri the URI template
   • @return the created builder
   • @since 5.3 */ ```

Documentation should be specific to the code at hand rather than copied from similar classes, and should clarify edge cases and expected behaviors.
