How to get Record Type developer name in Apex ?

Hi All,

Before summer 18, we used to write SOQL query to get developer name of a particular record type, now SOQL query is not required. 

This is my earlier post where recordtypeinfo method has been explained. What can we do using those methods.

1. How can we get Record Type Id of an object ?

    a.  Lets assume we know the record type name. say its "Inquiry".

Id objectRecordTypeId = Schema.SObjectType.CASE.getRecordTypeInfosByName().get('Inquiry').getRecordTypeId();
System.debug('objectRecordTypeId ---'+objectRecordTypeId ); 

    b.  Lets assume we know the record type developer name, say its "DevInquiry".

Id objectRecordTypeId = Schema.SObjectType.CASE.getRecordTypeInfosByDeveloperName().get('DevInquiry').getRecordTypeId();
System.debug('objectRecordTypeId ---'+objectRecordTypeId );

2.  How can we get record type developer name ? 

     a. Lets assume we know the record type name. say its "Inquiry".

String developerName = Schema.SObjectType.Case.getRecordTypeInfosByName().get('Inquiry').getDeveloperName();

Same code can be broken into following.

String recordTypename = 'Inquiry';
Schema.DescribeSObjectResult caseDesribe = Schema.SObjectType.Case;
Map<String,Schema.RecordTypeInfo> rtMapByName = caseDesribe.getRecordTypeInfosByName();
Schema.RecordTypeInfo rtByName =  rtMapByName.get(recordTypename);
String RecordTypeDeveloperName = rtByName.getDeveloperName();
System.debug('RecordTypeDeveloperName --'+RecordTypeDeveloperName ); 

  b.  Lets Assume we know recordType id.

String developerName = Schema.SObjectType.Case.getRecordTypeInfosById().get('012w0000000kc2XAAQ').getDeveloperName();

Please let me know if you have any confusion, I would be happy to help.
