org.polkadot.types.primitive.Int

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<java.math.BigInteger>, Codec

Direct Known Subclasses:

I128, I16, I256, I32, I64, I8

public class Int
extends AbstractInt

A generic signed integer codec. For Substrate all numbers are LE encoded, this handles the encoding and decoding of those numbers. Upon construction the bitLength is provided and any additional use keeps the number to this length. This extends BN, so all methods available on a normal BN object is available here.

public java.lang.String toHex()

Returns a hex string representation of the value

Specified by:

toHex in interface Codec

Specified by:

toHex in class AbstractInt

toU8a

public byte[] toU8a(boolean isBare)

Specified by:

toU8a in interface Codec

Specified by:
