Method details

getName

public String getName()

The network’s name.

getP2pkhVersion

public int getP2pkhVersion()

The Base58Check version byte of a P2PKH address.

getP2shVersion

public int getP2shVersion()

The Base58Check version byte of a P2SH address.

getBech32Hrp

public String getBech32Hrp()

The Bech32 human-readable part of a SegWit address.

getWifPrefix

public int getWifPrefix()

The first byte of a WIF private key.

getXpubVersion

public int getXpubVersion()

The BIP-32 public version bytes (xpub/tpub).

getXprvVersion

public int getXprvVersion()

The BIP-32 private version bytes (xprv/tprv).

getCoinType

public int getCoinType()

The BIP-44 coin type: 0 on mainnet, 1 on every test network.

toString

public String toString()

Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
