Using Constants ​

Learn how to use Apex Consts in your code.

Basic Usage ​

Access constants using the Consts class:

apex
// Account Type
String type = Consts.ACCOUNT.TYPE.PROSPECT;

// Account Rating
String rating = Consts.ACCOUNT.RATING.HOT;

// API Name
String apiName = Consts.ACCOUNT.API_NAME;

Creating Records ​

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

SOQL Queries ​

apex
List<Account> hotProspects = [
    SELECT Id, Name
    FROM Account
    WHERE Type = :Consts.ACCOUNT.TYPE.PROSPECT
    AND Rating = :Consts.ACCOUNT.RATING.HOT
];

Conditional Logic ​

apex
if (account.Type == Consts.ACCOUNT.TYPE.PROSPECT) {
    // Prospect logic
} else if (account.Type == Consts.ACCOUNT.TYPE.CUSTOMER_DIRECT) {
    // Customer logic
}

Switch Statements ​

apex
switch on account.Rating {
    when 'Hot' {
        // Use constants for comparison
        if (account.Rating == Consts.ACCOUNT.RATING.HOT) {
            // Hot account logic
        }
    }
    when 'Warm' {
        // Warm account logic
    }
}

Updating Records ​

apex
Account acc = [SELECT Id, Type FROM Account WHERE Id = :accountId];
acc.Type = Consts.ACCOUNT.TYPE.CUSTOMER_DIRECT;
acc.Rating = Consts.ACCOUNT.RATING.HOT;
update acc;

Best Practices ​

  1. Always use constants instead of hard-coded strings
  2. Import at class level if using extensively
  3. Use in validation rules via formulas when possible
  4. Document when you deviate from constants
