类 RLPItem

java.lang.Object

org.brewchain.sdk.contract.rlp.RLPItem

直接已知子类:

RLPList, RLPString

public abstract class RLPItem
extends java.lang.Object

An immutable view of a portion of a byte array containing RLP-encoded data, starting at index (inclusive) and ending at endIndex (exclusive), representing a single item (either a string or list). Useful when decoding or otherwise manipulating RLP items. Created by Evo on 1/19/2017.
