Email

This example shows how you construct an email from a name field, then adding a random email domain.

Mask Email
task MyTaskName
{
    // Anonymize - Mask various fields
    update CUSTOMER Anonymize_CUSTOMER
		// Create email based on the newly created name
		mask EMAIL CUSTOMER_EMAIL
			format %s@%s
			transform Email
			unique
			column NAME
			file src/main/resources/email.txt random-order
}

Notice

the "transform Email" makes a valid email format by replacing spaces and illegal email characters
"unique" makes sure the generated email is unique to satisfy constraints. If it is not unique it will try again, in this case with a different suffix.

The resource files, simple list of names whereas newline is used as delimiter
