Sharing Records using Trigger:

Sharing Records using Trigger:
This example shows how to share records after inserting depends on user you selected before creating the record.The trigger looks like this
trigger Hiring_Manager_Position_Share on Position__c (after insert) {
    if(trigger.isInsert){
        List<Position__Share> posShare = new List<Position__Share>();
        for(Position__c pos : trigger.new){
            Position__Share hiringManagerShare = new Position__Share();
            hiringManagerShare.ParentId = pos.Id;
            hiringManagerShare.UserOrGroupId = pos.Hiring_Manager__c;
            hiringManagerShare.AccessLevel = 'edit';
            hiringManagerShare.RowCause = Schema.Position__Share.RowCause.Hiring_Manager__c;
            posShare.add(hiringManagerShare);
        }
        Database.SaveResult[] posShareInsertResult = Database.insert(posShare, false);  
    }
}

Dynamic Approval:

Dynamic Approval:
We can achieve dynamic approval by creating a custom object and upload all the approve rs  related to your  business logic. In this example first create a custom object Position Approval Matrix and create list of records related to each department.The class and trigger looks like this

public class PositionApproval {
// Author: Mike Dannenfeldt, Etherios

static final Map<String,Position_Approval_Matrix__c> APPROVAL_MAP_CONST;

static {
APPROVAL_MAP_CONST = getPositionApprovalMap();
}

private static Map<String,Position_Approval_Matrix__c> getPositionApprovalMap(){
// build a Map from Department --> Approval Matrix record
Map<String,Position_Approval_Matrix__c> results = new Map<String,Position_Approval_Matrix__c>();
List<Position_Approval_Matrix__c> records = [select id,name,department__c,approver_1__c,approver_2__c,approver_3__c from Position_Approval_Matrix__c];
for(Position_Approval_Matrix__c record : records){
if (!results.containsKey(record.department__c)) results.put(record.department__c, record);
}
return results;
}

public static void setPositionApprovers(Position__c[] positions){
for (Position__c p:positions){
if (p.Department__c != null) {
if (APPROVAL_MAP_CONST.containsKey(p.Department__c)){
p.approver_1__c = APPROVAL_MAP_CONST.get(p.Department__c).approver_1__c;
p.approver_2__c = APPROVAL_MAP_CONST.get(p.Department__c).approver_2__c;
p.approver_3__c = APPROVAL_MAP_CONST.get(p.Department__c).approver_3__c;
} else {
p.approver_1__c = null;
p.approver_2__c = null;
p.approver_3__c = null;
}
}
}
}
}


trigger PositionApprovalTrigger on Position__c (before insert, before update) {
    PositionApproval.setPositionApprovers(Trigger.new);
}

Position record after insert looks like this

Fibonacci Sequence:

Fibonacci Sequence:This example shows how to generate Fibonacci series.Please check the Execute logs how it executes .

/* Fibonacci Sequence: The first two Fibonacci numbers are 0 and 1 and then the next Fibonacci number is found by adding the previous two together  */

// Setup the initial variables to hold the old number, current number, and fibonacci number
Integer oldNumber = 0;
Integer currentNumber = 1;
Integer fibonacciNumber = 0;

// use a loop to output all the fibonacci numbers between 0 and 100
while (fibonacciNumber < 100) {
     
      System.Debug(fibonacciNumber);  // output the Fibonacci number

      // calculate the next fibonacci number by adding the
      // current number to the old number
      fibonacciNumber= currentNumber + oldNumber;
     
      // now set the new values of the old and current numbers
      oldNumber = currentNumber;
      currentNumber = fibonacciNumber;
}
