MilestoneTriggerTimeCalculator Interface
Namespace
Implement the Support.MilestoneTriggerTimeCalculator interface to calculate a dynamic time trigger for a milestone based
on the milestone type, the properties of the case, and case-related
objects. To implement the Support.MilestoneTriggerTimeCalculator interface, you must first declare a class with the implements keyword as follows:
global class Employee implements Support.MilestoneTriggerTimeCalculator {
Next, your class must provide
an implementation for the following method:
global Integer calculateMilestoneTriggerTime(String caseId, String milestoneTypeId)The implemented method must be declared as global or public.
MilestoneTriggerTimeCalculator Methods
The following are instance methods for MilestoneTriggerTimeCalculator.
calculateMilestoneTriggerTime(caseId, milestoneTypeId)
Calculates the milestone trigger time based on the specified
case and milestone type and returns the time in minutes.
Syntax
public Integer calculateMilestoneTriggerTime(String caseId, String milestoneTypeId)
Parameters
- caseId
- Type: String
- ID of the case the milestone is applied to.
- milestoneTypeId
- Type: String
- ID of the milestone type.
Return Value
Type: Integer
The calculated trigger time in minutes.
MilestoneTriggerTimeCalculator Example Implementation
This sample class demonstrates the implementation of theSupport.MilestoneTriggerTimeCalculator interface. In this sample, the case’s priority and the milestone m1 determine that the time trigger is 18 minutes.
global class myMilestoneTimeCalculator implements Support.MilestoneTriggerTimeCalculator {
global Integer calculateMilestoneTriggerTime(String caseId, String milestoneTypeId){
Case c = [SELECT Priority FROM Case WHERE Id=:caseId];
MilestoneType mt = [SELECT Name FROM MilestoneType WHERE Id=:milestoneTypeId];
if (c.Priority != null && c.Priority.equals('High')){
if (mt.Name != null && mt.Name.equals('m1')) { return 7;}
else { return 5; }
}
else {
return 18;
}
}
}This test class can be used to test the implementation of Support.MilestoneTriggerTimeCalculator.
@isTest
private class MilestoneTimeCalculatorTest {
static testMethod void testMilestoneTimeCalculator() {
// Select an existing milestone type to test with
MilestoneType[] mtLst = [SELECT Id, Name FROM MilestoneType LIMIT 1];
if(mtLst.size() == 0) { return; }
MilestoneType mt = mtLst[0];
// Create case data.
// Typically, the milestone type is related to the case,
// but for simplicity, the case is created separately for this test.
Case c = new Case(priority = 'High');
insert c;
myMilestoneTimeCalculator calculator = new myMilestoneTimeCalculator();
Integer actualTriggerTime = calculator.calculateMilestoneTriggerTime(c.Id, mt.Id);
if(mt.name != null && mt.Name.equals('m1')) {
System.assertEquals(actualTriggerTime, 7);
}
else {
System.assertEquals(actualTriggerTime, 5);
}
c.priority = 'Low';
update c;
actualTriggerTime = calculator.calculateMilestoneTriggerTime(c.Id, mt.Id);
System.assertEquals(actualTriggerTime, 18);
}
