    • toRlpObject

      Object toRlpObject()
      Build the nested RLP object representation of this item: [address, [storageKeys...]]. The returned value is suitable for inclusion in the object list passed to RLPEncoder.list/RLPEncoder.sequence.

    • accessListItemsToRlpObject

      static List<Object> accessListItemsToRlpObject(List<AccessListItem> items)
      Build the nested RLP object representation of an entire access list.
      Parameters:
      items - the access list items (may be null)
      Returns:
      a list of nested RLP objects, one per item

    • fromRlp

      static AccessListItem fromRlp(com.esaulpaugh.headlong.rlp.RLPItem item)
      Decode a single access list entry from its RLP representation.
      Parameters:
      item - the RLP item for a single entry
      Returns:
      the decoded item, or null if the entry is malformed

    • accessListItemsFromRlp

      static List<AccessListItem> accessListItemsFromRlp(com.esaulpaugh.headlong.rlp.RLPItem accessListItem)

    • encodeAccessList

      static byte[] encodeAccessList(List<AccessListItem> items)
      Encode a list of access list items to their canonical, self-contained RLP list bytes. An empty (or null) list encodes to an empty byte array so that the stored accessList field stays "" for the common empty case.
      Parameters:
      items - the access list items
      Returns:
      the RLP-encoded access list, or an empty byte array when there are no items

      Decode the stored accessList bytes (either empty or a self-contained RLP list) back into items.
      Parameters:
      accessList - the stored access list bytes
      Returns:
      the decoded items (empty when there are none)
