Field Details

EMPTY

public static Address EMPTY

The address the yellow paper denotes as "∅" and is represent by a zero-length byte sequence, unlike all other addresses which are 20-bytes long.

Not to be confused with ZERO.

Used as destination for contract creation.

ZERO

public static Address ZERO

An address composed of 20 zero bytes.

Not to be confused with EMPTY.

Used as coinbase for the genesis block.

bytes

public final byte[] bytes

The big-endian representation of the address. Usually 20-bytes long, zero-length if EMPTY.

Constructor Details

Address

public Address(@Retained
byte[] bytes)

Address

public Address(String hexString)

Method Details

from

public static Address from(String hexString)

Creates a natural from a hex-string (e.g. "0x95ad61b0a150d79219dcf64e1e6cc01f0b64c4ce").

If the hex string is empty or simply "0x", then the EMPTY address is returned.

If the post-0x part of the hex string is not 40 characters long, the address will be padded with zeroes at the start so that it is 20 bytes long.

parse

public static Address parse(RLP rlp)
                     throws RLPParsingException

Throws:

RLPParsingException
