The Winter ’24 release of the Salesforce Platform has brought significant improvements for Apex developers …
Here are highlights from article A Deep Dive into Winter ’24 Apex Enhancements
1. DataWeave in Apex:
– Simplifies data transformations between different formats such as CSV, JSON, XML, and Apex objects.
– Integrates MuleSoft’s DataWeave library into the Apex runtime.
– Allows the execution of DataWeave scripts in Apex code.
– Streamlines data transformations and eliminates the need for complex code.
2. Comparator interface and Collator class for sorting:
– Prior to Winter ’24 release, sorting non-primitive data types required writing a wrapper class implementing a Comparable interface.
– With the new Comparator interface, sort orders can be implemented without wrapper classes.
– List.sort() now accepts a class implemented using a Comparator interface.
– Example code provided for implementing custom sort order for a list of Accounts.
3. Simplified code examples:
– Code examples provided in the article demonstrate how to use DataWeave in Apex to convert a CSV string to Contact object records in Salesforce.
– Code snippets and complete code available in the apex-recipes sample app.
4. Resources for learning DataWeave:
– Recommendations for using the DataWeave playground and online tutorial to learn how to write DataWeave scripts.
– Suggested use of the DataWeave 2.0 (Beta) VisualStudio code extension and Code Builder for building and testing DataWeave scripts.
5. Sorting lists based on user locale:
– The Collator class allows sorting lists based on user locale.
– Each language has specific rules for sorting, and the Collator class helps implement these rules.
