Class UInt

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<java.math.BigInteger>, Codec, Compactable
    Direct Known Subclasses:

    public class UInt
extends AbstractInt
implements Compactable
    UInt A generic unsigned 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.
