# 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
