# Governance Object
A Governance Object (or "govObject") is a generic structure introduced in Divi Core v12.1 to allow for the creation of Budget Proposals, Triggers, and Watch Dogs. Class inheritance has been utilized to extend this generic object into a "Proposal" which is outlined throughout the remainder of this document. 

### `new GovObject([govObjectData])`

Creates a new `GovObject` object where:
  - `govObjectData` - optional data (allowed types are `json`, `jsonString`, `hex`, `buffer`, `GovObject`)

### Methods

####  `dataHex`  
Returns a dataHex representation (see above)
####  `fromObject`  
Allow to create a govObj from a json or stringifiedJSON obj
####  `fromString`
Allow to create a govObj from an hex string
####  `checkedSerialize`
Return an hexa string that can be used in dashd CLI
####  `serialize`
Return an hexa string
####  `inspect`
Returns a representation of the object
####  `toBuffer`
Return a buffer
####  `fromBuffer`
Allow to create a govObject from a buffer
####  `shallowCopy`
Allow to shallowCopy from another govObject

## Governance Object Creation

The following would create a blank govObject

```javascript
// instantiate a new govObject instance
var govObject = new GovObject();
```

Budget Proposals can be created from a valid JSON object (stringified or not)

```javascript
var jsonProposal = {
  name:"My First GovObject",
  start_epoch:1483228800, //timestamp in seconds
  end_epoch:1483747200, //Is valid if end_epoch>now_epoch
  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
  payment_amount:10,
  type:1,//In this case, it will cast a proposal
  url:"http://www.diviproject.org/proposal/first_proposal"
};

//Will instantiate the govObject given the json passed as arg for fromObject
govObject = govObject.fromObject(jsonProposal);
var govObject = new GovObject().fromObject(jsonProposal);


//It worth mentioning that fromObject can also be a valid stringified json.
var govObject = new GovObject().fromObject(JSON.stringify(jsonProposal));
```

Budget Proposals can be instantiated from a Buffer

```javascript
//Allow to create a new object from a given buffer
var fromBuff = new GovObject(govObjBuffer);
//Or
var fromBuff = new GovObject().fromBuffer(govObjBuffer);

//And from an hexa string
var fromString = new GovObject("5b5b2270726f706f736...");
//or
var fromString = new GovObject().fromString("5b5b2270726f706f736...")
```

You can display a hex-encoded representation of a Budget Proposal with a simple "toString()"

```javascript
var fromString = new GovObject("5b5b2270726f706f736...");

var hexString = fromString.toString();
//or
var hexString = fromString.serialize();
```

Logging the object will also return a hex-encoded representation of the object

```javascript
var fromString = new GovObject("5b5b2270726f706f736...");

console.log(fromString) //<GovObject: 5b5b2270726f706f7...>
//Or using the method
fromString.inspect();
```

You could shallowcopy a first govObj into a second one

```javascript
proposal.url="http://diviproject.org/badUrl"
var shallowCopyProposal = proposal.shallowCopy();
proposal.url="http://diviproject.org/fixedUrl"

console.log(proposal.url!==shallowCopyProposal.url)//return true as it's a copy
console.log(proposal!==shallowCopyProposal)//return true
```

Finally you are able to get the dataHex from the object

```javascript
var fromString = new GovObject("5b5b2270726f706f736...");

fromString.dataHex()//Give a stringified json [['proposal',{name:"My First GovObject",....}]]

//You could get back the given JSON object by doing so
var JSONObject = JSON.parse(fromString.dataHex())[0][1]);
```

## GovObject Types:

Each of theses types are inherited from govObject allowing the same methods to be callable.

* Proposal `type:1` : Allow to create a proposal which inherit govObject method and overwrite them when needed

```javascript
var jsonProposal = {
  name:"My First Proposal",
  start_epoch:startDate,
  end_epoch:endDate,
  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
  payment_amount:10,
  type:1,
  url:"http://www.diviproject.org"
};

var proposal = new Proposal();
// create a new proposal from a stringified JSON object
proposal = proposal.fromObject(JSON.stringify(jsonProposal));

var shallowCopy = proposal.shallowCopy(); //As proposal inherits govObject

//Return an hex equivalent of the proposal
var hexProposal = proposal.serialize()
```
