## Usage

```js
const abi = require('ethjs-abi');
const SimpleStoreABI = [{"constant":false,"inputs":[{"name":"_value","type":"uint256"}],"name":"set","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"get","outputs":[{"name":"storeValue","type":"uint256"}],"payable":false,"type":"function"},{"anonymous":false,"inputs":[{"indexed":false,"name":"_newValue","type":"uint256"},{"indexed":false,"name":"_sender","type":"address"}],"name":"SetComplete","type":"event"}];

const setInputBytecode = abi.encodeMethod(SimpleStoreABI[0], [24000]);

// returns 0x60fe47b10000000000000000000000000000000000000000000000000000000000005dc0

const setOutputBytecode = abi.decodeMethod(SimpleStoreABI[0], "0x0000000000000000000000000000000000000000000000000000000000000001");

// returns  Result { '0': true }

const getInputBytecode = abi.encodeMethod(SimpleStoreABI[1], []);

// returns 0x6d4ce63c

const getMethodOutputBytecode = abi.decodeMethod(SimpleStoreABI[1], "0x000000000000000000000000000000000000000000000000000000000000b26e");

// returns Result { '0': <BN: b26e>, storeValue: <BN: b26e> }

const SetCompleteInputBytecode = abi.encodeEvent(SimpleStoreABI[2], [24000, "0xca35b7d915458ef540ade6068dfe2f44e8fa733c"]);

// returns 0x10e8e9bc0000000000000000000000000000000000000000000000000000000000005dc0000000000000000000000000ca35b7d915458ef540ade6068dfe2f44e8fa733c

const SetCompleteOutputBytecode = abi.decodeEvent(SimpleStoreABI[2], "0x0000000000000000000000000000000000000000000000000000000000000d7d000000000000000000000000ca35b7d915458ef540ade6068dfe2f44e8fa733c", ["0xc36800ebd6079fdafc3a7100d0d1172815751804a6d1b7eb365b85f6c9c80e61"]);

/* returns   Result {
  '0': <BN: d7d>,
  '1': '0xca35b7d915458ef540ade6068dfe2f44e8fa733c',
  _newValue: <BN: d7d>,
  _sender: '0xca35b7d915458ef540ade6068dfe2f44e8fa733c' }
*/

const methodSig = abi.encodeSignature(SimpleStoreABI[2]);

/* returns 0x10e8e9bc */
```

for contract SimpleStore:

```
pragma solidity ^0.4.4;

contract SimpleStore {
  uint store;

function set(uint256 _value) returns (bool) {
    store = _value;

SetComplete(store, msg.sender);

return true;
  }

function get() returns (uint256 storeValue) {
    return store;
  }

event SetComplete(uint256 _newValue, address _sender);
}
```
