Validation Without Torture: Clean Checks in OpenEdge

Readable, scalable, and portable across contexts.

Validation logic in OpenEdge often spirals into tangled IF statements and brittle one-off checks. But it doesn’t have to. With ValidatorUtil.cls, you get a focused set of tools for validating structured input—without the chaos.

This utility class from OE Essentials helps you enforce data integrity with reusable, testable methods.

What It Actually Solves

📧 Email Address Validation: Check if an email string follows standard formatting rules—no regex required.

🌐 URL and IP Address Checks: Validate IPv4, IPv6, and URL formats using built-in logic and Unix-based libraries.

📱 Phone Number Validation: Confirm that phone numbers meet expected patterns, especially useful for form inputs and contact records.

💳 Credit Card Number Validation: Use the Luhn algorithm to verify card numbers before processing.

Use Cases That Shine

Validating user-submitted contact info

Pre-checking API payloads for malformed fields

Enforcing format rules in config files or system settings

Building robust form validation for web or desktop UIs

e.g.

class class Tests.ValidatorUtilUnitTest: 

@Test. 

    method public void TestValidateEmailAddress(): 

  

        Assert:IsTrue(ValidatorUtil:ValidateEmailAddress("user@example.com"), "Expected valid email to pass"). 

        Assert:IsFalse(ValidatorUtil:ValidateEmailAddress("user@.com"), "Expected invalid email to fail"). 

        Assert:IsFalse(ValidatorUtil:ValidateEmailAddress("userexample.com"), "Expected email without @ to fail"). 

        Assert:IsTrue(ValidatorUtil:ValidateEmailAddress("user.name+tag@example.co.uk"), "Expected complex valid email to pass"). 

         

    end method. 

end class.

Why It Matters

Reusable logic across modules: Centralized validation means fewer bugs and easier maintenance.

Cleaner code, fewer conditionals: Replace verbose checks with expressive method calls.

Predictable behavior: Built-in methods handle edge cases so you don’t have to.

Final Thought

ValidatorUtil.cls helps you write validation logic like a pro. Whether you’re checking emails, URLs, or credit card numbers, this class keeps your code clean and your data trustworthy.
