You've heard about the joys of using platform events from Jonathan in Advanced Logging Using Nebula Logger - their versatility and interoperability with exception handling being a primary example of where the two features dovetail nicely together. Something interesting starts to occur when your platform events start firing other platform events, especially when those platform events originate from Apex that is already running asynchronously| www.jamessimone.net
We owe our ability to understand abstractions in programming to philosophy; much as we owe a debt to mathematics for putting the theorems responsible for our code -- and computers -- to work into words. Consider the immortal words present in the Tao: A well-shut door will stay closed without a latch. Skillful fastening will stay tied without knots. One does not simply (walk into Mordor) build a door that works well. A factory for doors cannot provide you with the quality of worksmanship and p...| www.jamessimone.net
A few months ago I was tasked with replacing Declarative Lookup Rollup Summaries (DLRS) in an org suffering from frequent deadlocks. Rollup summary fields in Salesforce are plagued by severe limitations -- only being available on master-detail relationships being just the start of the list. Read on to learn about how I built Rollup to assist in orgs looking for DLRS-like flexibility with a much smaller performance overhead, complete with elastic scaling (go fast when you need to, slow when th...| www.jamessimone.net
Custom Permissions changed the game when it came to creating programmatic checks for feature management within Salesforce. Between Custom Metadata and Custom Permissions, Salesforce as a whole has been trying to gently move people away from permissions management by way of hierarchical custom settings. And there's a lot to love when it comes to Custom Permissions, in particular. Since Winter '18, the FeatureManagement.checkPermission method has enabled developers to easily implement permissio...| www.jamessimone.net
Setting delays programmatically within Apex represents a unique challenge. We don't have access to the current thread instructions that are being carried out, nor do we have any kind of higher-level `delay` function. While this is frequently fine for internal usage, where the last thing you would want is for your compiled code to be slow, that's not always the case when interacting with external APIs. It's common for APIs to be 'rate-limited' - go over the number of requests you're supposed t...| www.jamessimone.net
So-called Lazy evaluated functions have their actual execution delayed until a terminator function is called. It's common for lazy functions to be chained together using fluent interfaces, culminating with actions being performed when the terminator function is called. What can Salesforce developers writing Apex code stand to gain by learning more about lazy functions? Fluent interfaces -- or objects that return themselves during function calls -- also tend to satisfy one of the prerequisites...| www.jamessimone.net
The abstract enum class in Apex can be very helpful as a class-like object, but there are a few things you should keep in mind to avoid getting bitten by the use of enums.| www.jamessimone.net
