Constructor Detail

ScriptHash

public ScriptHash(byte[] scriptHash)

Constructs a new script hash from the given byte array. The array must represent the script hash in little-endian order and can be 160 (contract script hash) or 256 (global asset id) bits long.

Parameters:

scriptHash - The script hash in little-endian order.

ScriptHash

public ScriptHash(java.lang.String scriptHash)

Constructs a new script hash from the given hexadecimal string. The string must represent the script hash in big-endian order and can be 160 (contract script hash) or 256 (global asset id) bits long.

Parameters:

scriptHash - The script hash in big-endian order.

Method Detail

length

public int length()

Gets the length of the script hash byte array.

Returns:

the length.

toArray

public byte[] toArray()

Gets the script hash as a byte array in little-endian order.

Returns:

the script hash byte array in little-endian order.

toString

public java.lang.String toString()

Gets the script hash as a hexadecimal string in big-endian order without the '0x' prefix.

Overrides:

toString in class java.lang.Object

Returns:

the script hash as hex string in big-endian order.

toAddress

public java.lang.String toAddress()

Derives the address corresponding to this script hash.

Returns:

the address.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

fromAddress

public static ScriptHash fromAddress(java.lang.String address)

Creates a script hash from the given address.

Parameters:

address - The address from which to derive the script hash.

Returns:

the script hash.

fromPublicKey

public static ScriptHash fromPublicKey(byte[] publicKey)

Creates a script hash from the given public key.

TODO 29.07.19 claude: What form does the public key need to have?

Parameters:

publicKey - The key to calculate the script hash for.

Returns:

the script hash.

fromPublicKeys

public static ScriptHash fromPublicKeys(int signingThreshold,
                                        byte[]... publicKeys)

Creates a script hash from the given public keys and signing threshold.

The signing threshold is the number of signatures needed for a valid transaction created with the public keys. It is needed to create the proper verification script.

Parameters:

signingThreshold - The signing threshold.

publicKeys - The public keys.

Returns:

the script hash.

fromScript

public static ScriptHash fromScript(byte[] script)

Creates a script hash from the given script in byte array form.

Parameters:

script - The script to calculate the script hash for.

Returns:

the script hash.

fromScript

public static ScriptHash fromScript(java.lang.String script)

Creates a script hash from the given script in hexadecimal string form.

Parameters:

script - The script to calculate the script hash for.

Returns:

the script hash.

compareTo

public int compareTo(ScriptHash o)

Specified by:

compareTo in interface java.lang.Comparable<ScriptHash>
