# Density

[![Join the chat at https://gitter.im/axic/density](https://badges.gitter.im/axic/density.svg)](https://gitter.im/axic/density?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

Density is a library or collection of useful modifiers and methods for [Solidity](https://ethereum.github.io/solidity/), one of the high-level languages for the Ethereum virtual machine (EVM).

## Usage

Either import the whole library:

```js

import "density.sol"

contract Test is owneronly, mortal {

  function Test() {

  }

  function method(string arg) owneronly {

    return strconcat("Hello ", arg);  

  }

}

```

Or just the parts you need:

```js

import "interfaces/token.sol"

contract Test {

  function Test() {

  }

  function method(address _address) {

    IToken token = IToken(_address);

    if (token.balanceOf(this) > 1 ether)

      // We are happy

  }

}

```
