Interface GenericContractValidator<T extends AbstractContractModel>

  • Type Parameters:
    T -
    All Known Subinterfaces:
    AccessContractValidator, IngestContractValidator, ManagementContractValidator

    public interface GenericContractValidator<T extends AbstractContractModel>
    Used to validate contracts (any class that extends AbstractContractModel) and to apply acceptance rules. Bellow the example of usage :
     private static GenericContractValidator checkDuplicateInDatabaseValidator() {
        return (contract, contractName) -> {
            GenericRejectionCause rejection = null;
            boolean exist = ... exists in database?;
            if (exist) {
               rejection = GenericRejectionCause.rejectDuplicatedInDatabase(contractName);
            return (rejection == null) ? Optional.empty() : Optional.of(rejection);
    The call the method like this to validate the contract c: GenericRejectionCause rejection = checkDuplicateInDatabaseValidator().validate(c, c.getName()); Check if rejection is present then do the resolution
