Salesforce Best Features available

 Salesforce Code Samples & Best Features available:

1. Get merged body without extra effort.

EmailTemplate emailTemplate = [Select Id FROM EmailTemplate where name = 'Test1'];  

Messaging.SingleEmailMessage email = Messaging.renderStoredEmailTemplate(emailTemplate.Id,

userinfo.getUserId(),AccountObj.Id);

system.debug(email.plainTextBody);

2. Business Hour Calculations example in apex:

public static Boolean checkBusinessHour(){

        //business hour logic

        List<BusinessHours> defaultBusinessHours = [SELECT Id FROM BusinessHours WHERE Name='Default' 

AND IsDefault= TRUE AND IsActive=TRUE Limit 1];

        

        // Find whether the time is within the default business hours

        return BusinessHours.isWithin(defaultBusinessHours[0].id, System.now());

    }

3. Check boolean expression in apex:

public class BooleanExpressionHandler {

    static Map<String, String> logicTypes = new Map<String, String>();

    static Map<String, Map<String, String>> expressionLogic = new Map<String, Map<String, String>>();

    

    public static Boolean eval(String expression) {        

        // If expression contains all TRUE or FALSE

        if(expression.containsNone('FALSE')) { return TRUE; }        

        if(expression.containsNone('TRUE')) { return FALSE; }

        

        fillLogic();

        

        return Boolean.valueOf(evaluateExpression(expression.toUpperCase()));

    }

    

    public static String evaluateExpression(String expression) {        

        for(String logicType : logicTypes.keySet()) {

            if(expression.contains(logicType)) {

                expression = simplifyExpression(expression, logicTypes.get(logicType));

            }

        }

        

        if(expression.contains('AND') || expression.contains('OR') || expression.contains('(')) {

            expression = evaluateExpression(expression);

        }

        

        return expression;

    }

    

    public static string simplifyExpression(String expression, String LogicType){

        Map<String, String> Logic = new Map<String, String>(expressionLogic.get(LogicType));

        

        for(String key : Logic.keySet()) {

            expression = expression.replace(key, Logic.get(key));

        }

        

        return expression;

    } 

    

    public static void fillLogic() {

        Map<String, String> ANDLogic = new Map<String, String>();

        Map<String, String> ORLogic = new Map<String, String>();

        Map<String, String> BRACELogic = new Map<String, String>();

        

        logicTypes.put('AND', 'AND');

        logicTypes.put('OR', 'OR');

        logicTypes.put('(', 'BRACES');

        

        // AND Logic

        ANDLogic.put('TRUE AND TRUE', 'TRUE');

        ANDLogic.put('TRUE AND FALSE', 'FALSE');

        ANDLogic.put('FALSE AND TRUE', 'FALSE');

        ANDLogic.put('FALSE AND FALSE', 'FALSE');

        expressionLogic.put('AND', ANDLogic);

        

        // OR Logic

        ORLogic.put('TRUE OR TRUE', 'TRUE');

        ORLogic.put('TRUE OR FALSE', 'TRUE');

        ORLogic.put('FALSE OR TRUE', 'TRUE');

        ORLogic.put('FALSE OR FALSE', 'FALSE');

        expressionLogic.put('OR', ORLogic);

        

        // Braces Logic

        BRACELogic.put('(TRUE)', 'TRUE');

        BRACELogic.put('(FALSE)', 'FALSE');

        expressionLogic.put('BRACES', BRACELogic);

    }

}

4. Bypass Trigger/Validation Rules/Process Builder

Firstly we need to create the custom setting of hierarchy type.

Create record into custom setting as shown in below screenshot.

Use below code into Triggers:

BypassSetting__c triggerSetting = BypassSetting__c.getInstance();

    if(triggerSetting !=null && !triggerSetting.Bypass_Trigger__c){

        // Trigger Logic

    }

5. Code to split list into particular size.

public static List<List<Account>> splitList(List<Account> recordList, Integer splitSize){

        List<List<Account>> resultList = new List<List<Account>>();

        List<Account> tempList = new List<Account>();

        Integer index = 0, count = 0, size = recordList.size();

        while(index < size) {

            tempList.add(recordList.get(index++));

            ++count;

            if(count == splitSize) {

                resultList.add(tempList);

                tempList = new List<Account>();

                count = 0;

            }

        }

        if(!tempList.isEmpty()) {

            resultList.add(tempList);

        }

        return resultList;

    }

6. fetch a field value from a related parent object

sObject acc = [SELECT Owner.Profile.Name FROM Account LIMIT 1]; String profileName = (String) acc.getSobject('Owner').getSobject('Profile').get('Name'); System.debug(profileName);

7.
