Trigger Controller

Trap instance actually is a controller for the trigger handlers created by it. The code below shows the relationship:

TriggerHandler handler = Trap.getInstance().find('Case');

Here the Trap controller creates the trigger handler for Case if it is not found, and returns it. Besides creating the trigger handlers, the trigger controller provides much more features.

Trap.getInstance()
    .setEnabled('Case', true) // enable the CaseTrigger
    .setMaxReEntry('Case', 3) // re-entered for 3 times at most
    .setUsingNewTransaction('Case', true); // new transaction in trigger
