Simple Summary

Adapt to solidity_0.8.4.

Abstract

Solidity_0.8.4 supports custom errors via the error keyword and introduce the revert statement. To adapt to solidity_0.8.4 we need add Error type in java-tron smart contract ABI.

Motivation

To adapt to solidity_0.8.4 we need add Error type in java-tron smart contract ABI.

Specifications

Add Error = 6 EntryType in message ABI in smart_contract.proto file.

message ABI {
    message Entry {
      enum EntryType {
        UnknownEntryType = 0;
        Constructor = 1;
        Function = 2;
        Event = 3;
        Fallback = 4;
        Receive = 5;
        Error = 6;
      }
      message Param {
        bool indexed = 1;
        string name = 2;
        string type = 3;
      }
      enum StateMutabilityType {
        UnknownMutabilityType = 0;
        Pure = 1;
        View = 2;
        Nonpayable = 3;
        Payable = 4;
      }

      bool anonymous = 1;
      bool constant = 2;
      string name = 3;
      repeated Param inputs = 4;
      repeated Param outputs = 5;
      EntryType type = 6;
      bool payable = 7;
      StateMutabilityType stateMutability = 8;
    }
    repeated Entry entrys = 1;
  }
