Interface EmailerAPI

All Known Implementing Classes:

Emailer, TestEmailer

public interface EmailerAPI

Provides application with emailing functionality.
Sending email can be synchronous (caller's thread is blocked until email is delivered to SMTP server) or asynchronous (email is persisted in a DB queue and sent later by scheduled task).
In order to send emails asynchronously, you should register a scheduled task that periodically invokes processQueuedEmails() method.
