Web3j-Cli does not generate correct java methods for view solc methods

2
votes

I would really appreciate some help with this...

I have generated java smart contract wrappers for two smart contracts (SheepHelper and SheepFactory). When I try to use these methods in android I can only return TransactionReciept objects (Even for view functions)

Because of this I cannot read any data contained in the Smart Contracts.

  1. Is there something wrong with the way the wrapper methods were generated / Is this a web3j issue (Code below)
  2. Could there be something wrong with the versions I am using? (Web3j Version is: , Pragma is ^0.6.1, web3-cli version is: )
  3. Are there any alternate ways of calling smart contract get functions *such as getSheepTotal() to return values?

Any help would be appreciated!

Smart Contracts:

SheepHelper.sol

pragma solidity ^0.6;

import "./sheepFactory.sol";
contract SheepHelper is SheepFactory {


modifier onlyOwnerOf(uint _sheepId){
  require(msg.sender == sheepToOwner[_sheepId]);
  _;
}
  function getSheepsByOwner(address _owner) external view returns(uint[] memory) {
    uint[] memory result = new uint[](ownerSheepCount[_owner]);
    uint counter = 0;
    for (uint i = 0; i < sheeps.length; i++) {
      if (sheepToOwner[i] == _owner) {
        result[counter] = i;
        counter++;
      }
    }
    return result;
  }

  function getSheepById(uint _sheepId) public view returns(string memory, uint, uint, uint, string memory){
    Sheep memory sheep = sheeps[_sheepId];
    return (sheep.name, sheep.hp, sheep.dp, sheep.dna, sheep.imageAsset);
  }

  function getSheepTotal() external view returns (uint){
    return sheepCount;
  }

  function findMySheepTotal() external view returns (uint){
    return sheepCount;
  }
}

SheepFactory.sol

pragma solidity ^0.6;

contract SheepFactory{

  event NewSheep(uint sheepId, string name, uint dna, uint hp, uint dp, string imageAsset);

  uint dnaDigits = 16;
  uint dnaModulus = 10 ** dnaDigits;
  uint statModulus = 10 ** 1;

  struct Sheep {
    string name;
    uint dna;
    uint hp;
    uint dp;
    string imageAsset;
   }

  Sheep[] public sheeps;
  uint sheepCount = 0;
  mapping (uint => address) public sheepToOwner;
  mapping (address => uint) ownerSheepCount;

  function _createSheep(string memory _name, uint _dna, uint16 _hp, uint16 _dp) internal {
    string memory sheepPic = "https://image.shutterstock.com/image-vector/cute-funny-cartoon-kick-sheep-600w-1577287216.jpg";

    sheeps.push(Sheep(_name, _dna, _hp, _dp, sheepPic));
    sheepCount++;
    uint id = sheeps.length - 1;
    sheepToOwner[id] = tx.origin;
    ownerSheepCount[msg.sender]++;
    emit NewSheep(id, _name, _dna, _hp, _dp, sheepPic);
  }

  function _generateRandomDna(string memory _str) private view returns (uint) {
    uint rand = uint(keccak256(abi.encodePacked(_str)));
    return rand % dnaModulus;
  }

  function _generateRandomStats(string memory _str, uint _statModifier) private view returns (uint) {
    uint rand = uint(keccak256(abi.encodePacked(_str)));
    return (rand % statModulus) + _statModifier;
  }

  function createRandomSheep(string memory _name) public {
    //require(ownerSheepCount[msg.sender] == 0);
    uint randDna = _generateRandomDna(_name);
    uint16 randHp = 2;//_generateRandomStats(_name, 1);
    uint16 randDp = 1;//_generateRandomStats(_name, 0);
    randDna = randDna - randDna % 100;

    _createSheep(_name, randDna, randHp, randDp);
  }
}

Your generated contract wrapper is correct. To access your contract data you have to use the methods which have the name event in it. The ethereum virtual machine handles contract interaction as events and stores it in the log.

To get all past sheep events and listen to new sheep events use:

sheepContract.newSheepFlowable(DefaultBlockParameterName.EARLIEST,
                    DefaultBlockParameterName.LATEST).subscribe(response -> {
    /*doSomthing with response (which is of type NewSheepEventResponse )*/
});

You could also use web3j to fetch all your sheep events. E.g. if you want all your past sheep events use:

EthFilter ethFilter = new EthFilter(DefaultBlockParameterName.EARLIEST,
                    DefaultBlockParameterName.LATEST, sheepContract.getContractAddress());
ethFilter.addSingleTopic(EventEncoder.encode(contract.NEWSHEEP_EVENT));
EthLog newSheepEventLog = web3j.ethGetLogs(ethFilter).send();
