How do I run Apex class in user mode?
Use the inherited sharing keyword on an Apex class to run the class in the sharing mode of the class that called it. If with sharing is specified while writing a class, then all the sharing rules of the current user will be considered. You must explicitly specify this keyword.
What’s the difference between kernel mode and user mode?
The kernel is the core of the computer system. The key difference between User Mode and Kernel Mode is that user mode is the mode in which the applications are running and kernel mode is the privileged mode to which the computer enters when accessing hardware resources.
What is difference between kernel mode and user mode?
Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC. In User mode, the executing code has no ability to directly access hardware or reference memory.
What does it mean to have access to all objects in apex?
In system context, Apex code has access to all objects and fields— object permissions, field-level security, sharing rules aren’t applied for the current user. This strategy ensures that code doesn’t fail to run because of hidden fields or objects for a user.
Can you run Apex code under another user?
The runAs method doesn’t enforce user permissions or field-level permissions, only record sharing. You can use runAs only in test methods. I have not found any exception to this rule, nor any workaround.
Do you have to explicitly set keyword for apex class?
You have to explicitly set this keyword for the class because Apex code runs in system context. In system context, Apex code has access to all objects and fields— object permissions, field-level security, sharing rules aren’t applied for the current user.
Can a class run in apex without a sharing declaration?
Apex without a sharing declaration is insecure by default. Designing Apex classes that can run in either with sharing or without sharing mode at runtime is an advanced technique. Such a technique can be difficult to distinguish from one where a specific sharing declaration is accidentally omitted.
