Annotation

@Documented

@Target(value: [FIELD, METHOD, PARAMETER, TYPE_USE, ANNOTATION_TYPE])
@Retention(value: RUNTIME)
@jakarta.validation.Constraint(validatedBy: [])
@interface RandomUuidFormatConstraint

The annotated element must be well-formed random UUID string.

The version of random UUID string is 4, and the variant is 2. In the following UUID string representation, character M must have a value of 4 (version), while character N must have a value between 8 and B (variant):

   4dd180d4-c554-4235-85be-3dfed42c316d
                 |    |
   xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
 

This constraint accepts only String types.

In default validator implementation, default message interpolation keys (when message annotation param is empty) are org.klokwrk.lib.lo.validation.constraint.RandomUuidFormatConstraint.invalidRandomUuidFormatMessage and org.klokwrk.lib.lo.validation.constraint.RandomUuidFormatConstraint.invalidUuidFormatMessage. Default implementation uses org.klokwrk.lib.lo.validation.constraint.RandomUuidFormatConstraint.invalidUuidFormatMessage when corresponding string cannot be parsed into a UUID. Similarly, default implementation uses org.klokwrk.lib.lo.validation.constraint.RandomUuidFormatConstraint.invalidRandomUuidFormatMessage when corresponding string does represent an UUID but is not a random UUID (version 4 and variant 2).

When custom annotation message parameter value is specified, it can be either a reference to the resource bundle key (must be enclosed in curly braces '{}'), or a hardcoded message. In resource bundle and in the hardcoded message, interpolation expressions must be enclosed in curly braces starting with a dollar sign '${}'.
