Apex Reference Guide
Apex is a strongly typed, object-oriented programming language that allows developers
to execute flow and transaction control statements on the Salesforce Platform server, in
conjunction with calls to the API. This reference guide includes built-in Apex classes,
interfaces, enums, and exceptions, grouped by namespace. It also includes Apex DML
statements to insert, update, merge, delete, and restore data in Salesforce.
For information on the Apex development process, see Apex Developer Guide.
