Commit(ITrie)

Commits given trie to storage. Returned ITrie must be identical to the one obtained from GetStateRoot(Nullable<HashDigest<SHA256>>) with resulting ITrie's Hash.

Declaration
ITrie Commit(ITrie trie)
Parameters
Type Name Description
ITrie trie

The ITrie to commit.
Returns
Type Description
ITrie

The committed ITrie. The committed ITrie's Root is guaranteed to be either null or a HashNode.
Remarks

Given trie must have originated from the same instance (or with an instance with the same reference to an IKeyValueStore). Otherwise, this is not guaranteed to work properly.

GetStateRoot(Nullable<HashDigest<SHA256>>)

Gets the state root trie of the stateRootHash from the state store.

Declaration
ITrie GetStateRoot(HashDigest<SHA256>? stateRootHash)
Parameters
Type Name Description
Nullable<HashDigest<SHA256>> stateRootHash

The state root hash of the state root trie to get. If null is passed the empty state root trie is returned.
Returns
Type Description
ITrie

The state root trie of the stateRootHash. If null is passed the empty state root trie is returned.
