Types

type Account

type Account interface {
	Type() AccountType

	GetNonce() uint64
	GetBalance() *big.Int
	GetHumanReadable() bool

	SetNonce(n uint64)
	SetBalance(b *big.Int)
	SetHumanReadable(b bool)

	// UpdateKey updates the account's key with the given key.
	UpdateKey(newKey accountkey.AccountKey, currentBlockNumber uint64) error

	// Empty returns whether the account is considered empty.
	// The "empty" account may be defined differently depending on the actual account type.
	// An example of an empty account could be described as the one that satisfies the following conditions:
	// - nonce is zero
	// - balance is zero
	// - codeHash is the same as emptyCodeHash
	Empty() bool

	// Equal returns true if all the attributes are exactly same. Otherwise, returns false.
	Equal(Account) bool

	// DeepCopy copies all the attributes.
	DeepCopy() Account

	// String returns all attributes of this object as a string.
	String() string
}

Account is the Klaytn consensus representation of accounts. These objects are stored in the main account trie.
