Class AbstractEmailValidator<A extends Annotation>

java.lang.Object

org.hibernate.validator.internal.constraintvalidators.AbstractEmailValidator<A>

All Implemented Interfaces:

ConstraintValidator<A,CharSequence>

Direct Known Subclasses:

EmailValidator, EmailValidator

public class AbstractEmailValidator<A extends Annotation>
extends Object
implements ConstraintValidator<A,CharSequence>

Checks that a given character sequence (e.g. string) is a well-formed email address.

The specification of a valid email can be found in RFC 2822 and one can come up with a regular expression matching all valid email addresses as per specification. However, as this article discusses it is not necessarily practical to implement a 100% compliant email validator. This implementation is a trade-off trying to match most email while ignoring for example emails with double quotes or comments.

Implements the validation logic. The state of value must not be altered.

This method can be accessed concurrently, thread-safety must be ensured by the implementation.

Specified by:

isValid in interface ConstraintValidator<A extends Annotation,CharSequence>

Parameters:

value - object to validate

context - context in which the constraint is evaluated
