Custom Apex utility for merging strings containing merge fields and replacing with values
This utility provides a way to pass a string containing merge fields using {{ field_name }} syntax, and getting the SObject record value.
Eg.
String myTemplate = 'Hey {{ FirstName }}, your email address is {{ Email }} and account name is {{ Account.Name }}';
String myResult = MergeFieldUtility.replaceMergeFieldsWithValues (
myTemplate, // The string to merge
'0032800000YWeRQ' // The record ID
);
system.debug(myResult);
