API
new Account([data])
Creates an new account object
data
- an account can be initiailized with either abuffer
containing the RLP serialized account. Or anarray
of buffers relating to each of the tx Properties, listed in order below. For example.
var raw = [
'02', //nonce
'0384', //balance
'56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421', //stateRoot
'c5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470' //codeHash
];
var tx = new Account(raw);
Or lastly an Object
containing the Properties of the transaction
var raw = {
nonce: '',
balance: '03e7',
stateRoot: '56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421',
codeHash: 'c5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470'
};
var tx = new Account(raw);
For Object
and Arrays
each of the elements can either be a Buffer
, hex String
, Number
, or an object with a toBuffer
method such as Bignum
.
Account
Properties
nonce
- The account's nonce.balance
- The account's balance in wiestateRoot
- the stateRoot for the storage of the contractcodeHash
- the hash of the code of the contract
Account
Methods
Account.isEmpty()
Returns a Boolean
determining if the account is empty
account.isContract()
Returns a Boolean
deteremining if the account is a contract
account.isPrecompiled
Returns a Boolean
deteremining of the account is a preCompiled contract
account.serialize()
Returns the RLP serialization of the account as a Buffer
acount.toJSON([object])
Returns the account as JSON
object
- aBoolean
that defaults to false. Ifobject
is true then this will return an object else it will return anarray
.
account.getCode(trie, cb)
Fetches the code from the trie
trie
- the trie to storing the accountscb
- the callback
account.setCode(trie, code, cb)
Stores the code in the trie
trie
- the triecode
- aBuffer
cb
- the callback
account.getStorage(trie, key, cb)
Fetches key
from the account's storage
account.setStorage(trie, key, val, cb)
Stores a val
at the key
in the contract's storage
