interface MerkleTrie<in K, V> (source)
A Merkle Trie.
get |
Returns the value that corresponds to the specified key, or an empty byte array if no such value exists. abstract suspend fun get(key: K): V? |
getAsync |
Returns the value that corresponds to the specified key, or an empty byte array if no such value exists. open fun getAsync(key: K): AsyncResult<V?>open fun getAsync(dispatcher: CoroutineDispatcher, key: K): AsyncResult<V?> |
put |
Updates the value that corresponds to the specified key, creating the value if one does not already exist. abstract suspend fun put(key: K, value: V?): Unit |
putAsync |
Updates the value that corresponds to the specified key, creating the value if one does not already exist. open fun putAsync(key: K, value: V?): AsyncCompletionopen fun putAsync(dispatcher: CoroutineDispatcher, key: K, value: V?): AsyncCompletion |
remove |
Deletes the value that corresponds to the specified key, if such a value exists. abstract suspend fun remove(key: K): Unit |
removeAsync |
Deletes the value that corresponds to the specified key, if such a value exists. open fun removeAsync(key: K): AsyncCompletionopen fun removeAsync(dispatcher: CoroutineDispatcher, key: K): AsyncCompletion |
rootHash |
Returns the KECCAK256 hash of the root node of the trie. abstract fun rootHash(): Bytes32 |
EMPTY_TRIE_ROOT_HASH |
The root hash of an empty tree. val EMPTY_TRIE_ROOT_HASH: Bytes32 |
