Tutorial 2

Apex Language Orientation

It’s like Java or .Net– Strongly typed with curly braces

Common primitive data types

Familiar collections and logic constructs

Classes and Interfaces and Inheritance

Familiar polymorphic exception handling

This is what it looks like

Invoking Apex Code

Can be executed directly– Execute Anonymous

Can be triggered by database changes– Insert, Update, Delete, before and after triggers

Can be directly called through REST– Custom Apex Rest Service

Invoked as the controller portion of a Visualforce page

Apex Has Data Manipulation Built In

Query is first class part of the language– [Select Id, Name From Account Where Country = ‘UK’]

Insert, update, delete and upsert

Full database transaction control– SetSavePoint and Rollback

Operates on sets of or single sObjects

Retrieving Data Using SOQL and SOSL

SOQL is like SQL, only one verb supported (select)– Aggregation, grouping, and geolocation are all

supported

– Relationship navigation, sub queries and anti joins are supported

SOSL is for searching for data across columns and tables– Full text search and polymorphic results across objects

– Supports abstract search field specification• Find “5559993344” in Phone Fields

What is an sObject?

It is a chunk of data, a kin to a record, but more– An sObject can contain a sef of other sObjects (child

records)

– All stored data is represented as an sObject

– They all have a universally unique Id (kind of like a foreign key)

Automatically available through a REST endpoint

Can have computed fields (we call them formula fields)

Working with sObjects

DML Demo

Implementing Triggers

Excellent choice to enforce business logic– Triggers fire no matter what caused the data change

Triggers operate in bulk– You should assume that more than one record is part of

the execution scope

Consider the use of Asynchronous options– Calling out to a web service, cascading changes to

many different objects

Implementing Triggers

Let’s look at some triggers…

Unit Testing in Apex

Built in support for testing– Test Utility Class Annotation

– Test Method Annotation

– Test Data build up and tear down

Unit test coverage is required– Must have at least 75% of code covered

Why is it required?

Apex Batch Processing

Governor Limits– Various limitations around resource usage

Asynchronous processing– Send your job to a queue and we promise to run it

Can be scheduled to run later– Kind of like a chron job

Writing Your Own REST Service with Apex

Aggregating DML– Most REST services are very granular

Implementing database transactions in REST– Enforce you business logic at the data layer

Common “servlet” model– Annotations to specify POST, GET, PATCH, DELETE

You control the URL Mapping for the resource

What can you do with Visualforce?

Framework to build custom user interfaces

Hosted natively on Force.com

Build streamlined UX

Create internal and public facing pages

Customize for different devices

Leverage other web technologies

Custom ObjectsStandard

Controllers and Apex

Visualforce

Mobile Visualforce in Salesforce1

Where can I put Visualforce Pages?– Navigation Menu

– Publisher

– Record Homepage – Mobile Cards

Build UI with ‘Mobile Ready’ techniques (responsive, CSS, etc)

Navigation: sforce.one object– Ex: sforce.one.navigateToRelatedList(relatedListId,

parentRecordId)

‘Available for Salesforce Mobile apps’ flag enabled

Developers are responsible for making the VF page ‘mobile ready’

• Use a Responsive Design framework like Bootstrap or Mobile Design templates

• Leverage touch and swipe events where appropriate

Use JavaScript Remoting/VF Remote Objects for better performance

Use HTML5 for device features like Geolocation and Camera access

Salesforce Canvas Overview

Enable integration of external applications securely within Salesforce1 from the native environment– Javascript API, Secure Authentication, Context Services,

X-Domain API, Eventing Model, App Registration and Management

When might you use Canvas?

Your data does not reside in salesforce.com– The data is best consumed in the context of salesforce,

but is not required to reside there

You have developers focused on other technologies– Sometimes Salesforce1 developers are hard to find

You have an existing application– Don’t need to reinvent the wheel
