Apex ConstsConstants Framework for Apex

Why Apex Consts? ​

Stop using hard-coded string literals scattered throughout your code. Apex Consts provides a centralized, type-safe way to manage constants:

Account acc = new Account(
    Name = 'My Account',
    Type = 'Prospect',  // Easy to mistype
    Rating = 'Hot'      // No autocomplete
);

if (acc.Type == 'Propsect') {  // Typo! Runtime error
    // ...
}

Account acc = new Account(
    Name = 'My Account',
    Type = Consts.ACCOUNT.TYPE.PROSPECT,  // Type-safe
    Rating = Consts.ACCOUNT.RATING.HOT    // Autocomplete
);

if (acc.Type == Consts.ACCOUNT.TYPE.PROSPECT) {  // Compile-time safety
    // ...
}

Quick Example ​

// Using Account constants
Account acc = new Account(
    Name = 'Acme Corp',
    Type = Consts.ACCOUNT.TYPE.PROSPECT,
    Rating = Consts.ACCOUNT.RATING.HOT
);
insert acc;

// Using Contact constants
Contact con = new Contact(
    FirstName = 'John',
    LastName = 'Doe',
    LeadSource = Consts.CONTACT.LEAD_SOURCE.WEB
);
insert con;

// Using Opportunity constants
Opportunity opp = new Opportunity(
    Name = 'Big Deal',
    StageName = Consts.OPPORTUNITY.STAGE_NAME.PROSPECTING,
    Type = Consts.OPPORTUNITY.TYPE.NEW_CUSTOMER,
    CloseDate = Date.today().addDays(30)
);
insert opp;

Features at a Glance ​

• ✅ Type-Safe - Compile-time checking prevents typos
• ✅ Autocomplete - IDE suggestions for all constants
• ✅ Memory Efficient - Singleton pattern with lazy loading
• ✅ Organized - Logical grouping with inner classes
• ✅ Extensible - Easy to add custom constants
• ✅ Standard Objects - Pre-built for Account, Contact, Opportunity, Profile
• ✅ SOLID Design - Follows best practices and design principles

How It Works ​

Apex Consts uses a singleton pattern with lazy initialization:

1. Singleton - Each const class is instantiated only once per transaction
2. Lazy Loading - Classes are only created when first accessed
3. Getter Pattern - Properties use getters to control instantiation

// First access creates instance
String type = Consts.ACCOUNT.TYPE.PROSPECT;  // AccountConsts created

// Later accesses reuse instance
String rating = Consts.ACCOUNT.RATING.HOT;   // Reuses same AccountConsts

// Other classes aren't created unless accessed
// ContactConsts not created yet - no memory used

This approach minimizes heap usage and improves performance.
