Why do single objects have one trigger?
An object oriented code base is more organized, predictable, and modular too! Control your order of execution – in Apex, “the order of execution isn’t guaranteed for multiple triggers on the same object.” This pattern gives you total order control.
How many triggers are possible per object?
The reason behind the principle of only one trigger per object is mainly due to the fact that in Salesforce we don’t have any way to guarantee order of execution for triggers on the same object.
What is trigger framework in Salesforce?
The SFDC Trigger Framework has an abstract TriggerHandler base class that handles execution and prevents recursion. Child classes inherit from the TriggerHandler class, and override one or more of the trigger context methods (like beforeInsert, beforeUpdate, or afterUpdate).
What is trigger factory in Salesforce?
These patterns provide an elegant way of coding triggers to avoid bad practices such as repetitive SOQL queries that can hit governor limits and multiple triggers over the same object.
What is advantage of trigger framework?
Why Trigger Framework They can interfere with one another and cause huge performance and debugging problems. Ensures triggers are consistently handled and only required code is needed. Allows for simple Triggers and handlers. Allow you to enforce different behavior for triggers that start a process vs.
Why do we use triggers in Salesforce?
Apex triggers enable you to perform custom actions before or after events to records in Salesforce, such as insertions, updates, or deletions. Triggers can be defined for top-level standard objects, such as Account or Contact, custom objects, and some standard child objects. Triggers are active by default when created.
Can we define two triggers with same event on single object?
You can have multiple triggers of the same type for the same statement for any given table. For example, you can have two BEFORE statement triggers for UPDATE statements on the employees table.
