Constructor Detail

LogicSigAccount

public LogicSigAccount(byte[] logic,
                       List<byte[]> args)

Creates a new escrow LogicSig Account The address of the account is the hash of its program (logic)

Parameters:

logic - the bytes of program

args - the arguments of the program

LogicSigAccount

public LogicSigAccount(byte[] logic,
                       List<byte[]> args,
                       PrivateKey privateKey)
                throws NoSuchAlgorithmException,
                       IOException

Creates a new delegated LogicSigAccount. This type of LogicSigAccount has the authority to sign transaction on behalf of another account, or so to say that account delegate the transaction signing to the program. If the delegating account is a multi-sig account, please pass in a multi-address for class construction (do not use this constructor in that case)

Parameters:

logic - the bytes of program

args - the arguments of the program

privateKey - the (only) private key of the delegating account

Throws:

NoSuchAlgorithmException

IOException

LogicSigAccount

public LogicSigAccount(byte[] logic,
                       List<byte[]> args,
                       PrivateKey privateKey,
                       MultisigAddress ma)
                throws IOException,
                       NoSuchAlgorithmException

Creates a new delegated LogicSigAccount. This type of LogicSigAccount has the authority to sign transaction on behalf of another account, or so to say that account delegate the transaction signing to the program. The delegated Account here is a multi-sig account. To add additional signature from other member, use appendMultiSig method.

Parameters:

logic - the bytes of program

args - the arguments of the program

privateKey - is the private key of one of the member of delegating multi-sig account

ma - is the multi-sig-address of the delegating account.

Throws:

IOException

NoSuchAlgorithmException

LogicSigAccount

public LogicSigAccount(LogicsigSignature lsig,
                       Ed25519PublicKey signerPublicKey)
                throws IllegalArgumentException,
                       NoSuchAlgorithmException

Creates a new delegated LogicSigAccount from existing LogicSig

Parameters:

lsig - is an existing LogicSig.

signerPublicKey - must be present if the LogicSig is delegated and the delegating account is backed by a single private key (i.e. not a multi-sig account). It must be the public key of the delegating account, or an error will be returned if it is present.

Throws:

IllegalArgumentException

NoSuchAlgorithmException

                           IOException,
                           NoSuchAlgorithmException

Adds a signature from the delegating multi-sig account

Parameters:

privateKey - is the private key of one of the member of delegating multi-sig account

Throws:

IllegalArgumentException

IOException

NoSuchAlgorithmException

isDelegated

public boolean isDelegated()

IsDelegated returns true iff. the LogicSig has been delegated to another account with a signature

Returns:

boolean

getAddress

public Address getAddress()
                   throws NoSuchAlgorithmException,
                          IllegalArgumentException

getAddress returns the address of the LogicSigAccount

Returns:

the address of the LogicSigAccount

Throws:

NoSuchAlgorithmException

IllegalArgumentException

signLogicSigTransaction

public SignedTransaction signLogicSigTransaction(Transaction tx)
                                          throws NoSuchAlgorithmException,
                                                 IOException
