Method Detail

redeemP2WPKH

public static TransactionWitness redeemP2WPKH(@Nullable
                                              TransactionSignature signature,
                                              ECKey pubKey)

Creates the stack pushes necessary to redeem a P2WPKH output. If given signature is null, an empty push will be used as a placeholder.

redeemP2WSH

public static TransactionWitness redeemP2WSH(Script witnessScript,
                                             TransactionSignature... signatures)

Creates the stack pushes necessary to redeem a P2WSH output.

of

public static TransactionWitness of(java.util.List<byte[]> pushes)

Construct a transaction witness from a given list of arbitrary pushes.

Parameters:

pushes - list of pushes

Returns:

constructed transaction witness

of

public static TransactionWitness of(byte[]... pushes)

Construct a transaction witness from a given list of arbitrary pushes.

Parameters:

pushes - list of pushes

Returns:

constructed transaction witness

read

public static TransactionWitness read(java.nio.ByteBuffer payload)
                               throws java.nio.BufferUnderflowException

Deserialize this transaction witness from a given payload.

Parameters:

payload - payload to deserialize from

Returns:

read message

Throws:

java.nio.BufferUnderflowException - if the read message extends beyond the remaining bytes of the payload

getPush

public byte[] getPush(int i)

getPushCount

public int getPushCount()

write

public java.nio.ByteBuffer write(java.nio.ByteBuffer buf)
                          throws java.nio.BufferOverflowException

Write this transaction witness into the given buffer.

Parameters:

buf - buffer to write into

Returns:

the buffer

Throws:

java.nio.BufferOverflowException - if the serialized data doesn't fit the remaining buffer

serialize

public byte[] serialize()

Allocates a byte array and writes this transaction witness into it.

Returns:

byte array containing the transaction witness

getMessageSize

public int getMessageSize()

Return the size of the serialized message. Note that if the message was deserialized from a payload, this size can differ from the size of the original payload.

Returns:

size of the serialized message in bytes

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
