public boolean isValid(CharSequence value, ConstraintValidatorContext constraintValidatorContext)

Implements jakarta.validation.ConstraintValidator.isValid.

Doc from jakarta.validation.ConstraintValidator.isValid.

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.

Parameters
value:CharSequence

object to validate

constraintValidatorContext:ConstraintValidatorContext

context in which the constraint is evaluated

Returns:boolean

false if value does not pass the constraint
