Methods

public static justWriteALogStatement(String toLog)

Method exists to demonstrate what it might look like to call a service layer method from a trigger handler.

Parameters

Param	Description
toLog	String to Log.

Example

AccountServiceLayer.justWriteALogStatement('Hello World');

public static changeShippingStreet(List<Account> accounts, System accessLevel)

SUPPRESSWARNINGS

Changes the account's Shipping Street field to a hardcoded value. You should do this kind of work in a before trigger, but this is a demo. Note: This method contains a false-positive PMD viloation around not checking FLS/CRUD before doing DML. This is because PMD is unaware of what the CanTheUser call right before it is doing - namely checking CRUD.

Parameters

Param	Description
accounts	List of account objects to change the shipping street on

Example

Account[] accounts = [SELECT Name FROM Account LIMIT 50];
AccountServiceLayer.changeShippingStreet(accounts);
System.debug([SELECT Name, ShippingStreet FROM Account WHERE id in : accounts]);

System.debug([SELECT Name, Description FROM Account WHERE id in : accounts]);
