ContractState

All Implemented Interfaces:
```
public interface ContractState

                    
```
Defines a contract state.
A contract state (or just "state") contains opaque data used by a contract program. It can be thought of as a disk file that the program can use to persist data across transactions.
States are immutable. Once created, they are never updated, instead, any changes must generate a new successor state. States can be updated (consumed) only once. The notary is responsible for ensuring there is no "double spending" by only signing a transaction if the input states are all free.
