TariffMarket (Power TAC accounting service 1.8.0-SNAPSHOT API)

All Known Implementing Classes:

TariffMarketService
```
public interface TariffMarket
```
Tariff Market Receives, validates, and stores new tariffs, enforces tariff validity rules. Generates transactions to represent tariff publication fees. Provides convenience methods to find tariffs that might be of interest to Customers.
Note that all methods driven by messages from the incoming message channel are polymorphic methods that select by argument type at runtime. They all return a TariffStatus instance that can be routed back to the originating broker.
