Can I use inherited contract in artifacts require statement

Question

Suppose I have 2 contracts A and B and I inherit B from A and add some code in contract B, when I use the artifacts.require() statement, should I include both the contracts or including only B will be enough?

Will the following code be fine to use A and B?

var B = artifacts.require("B");

module.exports = function(deployer) {

    deployer.deploy(B);

};

Answer 1

Yes, this code will work just fine. When you inherit a contract, only one contract will be created during deployment. So when you inherit a contract then the child contract will have the contents of the parent contact. Look at this example and understanding how you can implement it:

pragma solidity ^0.4.18;

contract A {

  uint256 public balance;

  function() public payable {

    balance = msg.value;

  }

}

contract B is A {

  uint256 i;

  A a;

  function B(address _a) public {

    a = A(_a);

  }

  function receiveForParent() public payable {

    a.transfer(msg.value);

  }

  function getParentBalance() public constant returns (uint256) {

    return a.balance();

  }

}
