changeShippingStreet(accounts, 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

Name	Type	Description
accounts	List<Account>	List of account objects to change the shipping street on
accessLevel	System.AccessLevel

Return Type

void

Example

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