In that session we talk about all below Trigger Framework
1) Trigger Handler Pattern
2) Trigger Framework using a Virtual Class
3) Trigger Framework using an Interface
4) An architecture framework to handle triggers
Why Trigger Framework ?
A framework may, however, greatly simplify your development efforts when your code base gets large. In a nutshell, your framework should have the following goals:-- Generic code that can be extended for any object
- Ensures triggers are consistently handled and only required code is needed
- Allows for simple Triggers and Handlers
- Handles routing for you
- Enforces consistent trigger behavior
- Easily allows for trigger bypasses
Trigger Handler Pattern
Please check this post to learn about Handler pattern and code. Lets talk about what is the advantage of Trigger Handler Patter.- Apex Class that handles trigger logic
- Allows code to be called from other code or tests
- Uses specific Trigger contexts and Trigger variables for routing
- Keep Triggers Simple
- Allow for greater flexibility
- Make code reusable
- Unit tests are much easier
Please check this recording for code walk-through. What is missing in Handler pattern ?
- Still duplicated code in every trigger
- How can we simplify things?
- How can we make our process repeatable?
Trigger Framework using a Virtual Class
Please check this post to learn more about Virtual Class Trigger Framework.
Please check this recording for code walk-through. Accomplishments with this Trigger framework :-
- 1 line trigger
- Only need to add handler methods that we want to use
- All routing is handled for us
Trigger Framework using an Interface
Please check this post to learn about this framework.
- 1 line trigger
- All routing is handled for us
- All handlers are consistent and will have the same methods
- Multiple ways to deactivate a trigger
An architecture framework to handle triggers
Please check this post to learn about this framework.
Please check this recording for code walk-through. Accomplishments with this Trigger framework :-
- 1 line trigger
- All routing is handled for us
- Establish all methods while letting us pick and choose which ones we want
- Individual event handler methods
