class MerklePatriciaTrie<V> : MerkleTrie<Bytes, V> (source)
An in-memory MerkleTrie.
valueSerializer - A function for serializing values to bytes.
Parameters
<init> |
Creates an empty trie. MerklePatriciaTrie(valueSerializer: (V) -> Bytes) |
get |
Returns the value that corresponds to the specified key, or an empty byte array if no such value exists. suspend fun get(key: Bytes): V? |
getAsync |
Returns the value that corresponds to the specified key, or an empty byte array if no such value exists. fun getAsync(key: Bytes): AsyncResult<V?> |
put |
Updates the value that corresponds to the specified key, creating the value if one does not already exist. suspend fun put(key: Bytes, value: V?): Unit |
putAsync |
Updates the value that corresponds to the specified key, creating the value if one does not already exist. fun putAsync(key: Bytes, value: V?): AsyncCompletion |
remove |
Deletes the value that corresponds to the specified key, if such a value exists. suspend fun remove(key: Bytes): Unit |
removeAsync |
Deletes the value that corresponds to the specified key, if such a value exists. fun removeAsync(key: Bytes): AsyncCompletion |
rootHash |
Returns the KECCAK256 hash of the root node of the trie. fun rootHash(): Bytes32 |
toString |
fun toString(): String |
create |
Create a trie. fun <V> create(valueSerializer: Function<V, Bytes>): MerklePatriciaTrie<V> |
storingBytes |
Create a trie with keys and values of type Bytes. fun storingBytes(): MerklePatriciaTrie<Bytes> |
storingStrings |
Create a trie with value of type String. fun storingStrings(): MerklePatriciaTrie<String> |
