Calling from Kotlin

Here's an example of calling this function from Kotlin code:

val value: Any = "[email protected]"
val address: EmailAddress? = EmailAddress.fromStringOrNull(value)
println(address != null) // true

Calling from Java

Here's an example of calling this function from Java code:

final Object value = "[email protected]";
final EmailAddress address = EmailAddress.fromStringOrNull(value);
System.out.println(address != null); // true

You can use the fromString function for throwing an exception instead of returning null in case of invalid value.

println(address != null) // true

Calling from Java

Here's an example of calling this function from Java code:

final Object value = "[email protected]";
final Object pattern = "^[a-z]+@[a-z]+\\.[a-z]+$";
final EmailAddress address =
    EmailAddress.fromStringOrNull(value, pattern);
System.out.println(address != null); // true

You can use the fromString function for throwing an exception instead of returning null in case of invalid value or pattern.
