Calling the Service layer


The preceding examples have shown the use of the service class methods from Visualforce Controller methods. Let's take a closer look at what is happening here, the assumptions being made, and also at an Apex Scheduler example. Other examples of service methods in action, such as from a Lightning Component, will feature throughout later chapters.

The following code represents code from a controller class utilizing StandardController that provides support for the Visualforce page associated with a Custom Button on the Race object. Notice how it wraps the record ID in Set, honoring the bulkified method signature:

public PageReferenceawardPoints(){
  try{
    RaceService.awardChampionshipPoints(new Set<Id> {standardController.getId() });
  }

  catch (Exception e){
    ApexPages.addMessages(e);
  }
  return null;
}

The constructor of these controllers is not shown, but it essentially stores StandardController or StandardSetController in a member variable for later...
