Solidity Function Signature - question about part of signature

Question

I'm looking at examples of Smart Contracts written in Solidity and I found a constructor with the signature:

constructor() ERC721Full("<Token name>", "<Token Symbol>") public {

}

what is the ERC721Full("", "") part of the signature? And how am I able to pass arguments into it?

Answer 1

You can hardcode it, or modify your constructor to have more parameters.

Code example:

contract A {
    string public name;
    constructor(string tokenName) public {
        name = tokenName;
    }
}

// Hardcode
contract B is A {
    constructor() A("My tokenName") public {

    }
}

// Add params to constructor
contract C is A {
    constructor(string tokenName) A(tokenName) public {

    }
}
