Annotation Type LevenshteinDistance

@Documented
 @Constraint(validatedBy=LevenshteinDistanceValidator.class)
 @Target(value={TYPE,ANNOTATION_TYPE})
 @Retention(value=RUNTIME)
public @interface LevenshteinDistance

The annotated bean must contain exact three properties:

• a field that has to be checked (option field1)
• a field which entry is compared (option field2)
• the minimum levenshtein distance both field entries must have (option minDistance)
• add the error to field1 (option addErrorToField1, default true)
• add the error to field2 (option addErrorToField2, default true)

The Levenshtein distance between the entry of fieldCompare and field is calculated, it must be equal or greater then the value of minDistance. not be empty (null or "").
Supported types are beans, null elements are considered valid.
