<a name="new_Vector_new"></a>

### new Vector([start], [end])
Vector model with helper types

## Usage
``` javascript
import { Vector } from 'type-enforcer';
```


| Param | Type |
| --- | --- |
| [start] | <code>Point</code> | 
| [end] | <code>Point</code> | 

<a name="Vector+isSame"></a>

### vector.isSame(vector2) ⇒ <code>Boolean</code>
Determine if another vector is the same as this one

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| vector2 | [<code>Vector</code>](#Vector) | 

<a name="Vector+invert"></a>

### vector.invert()
Switch the start and end points

**Kind**: instance method of [<code>Vector</code>](#Vector)  
<a name="Vector+toString"></a>

### vector.toString()
Get a string representation of the vector

**Kind**: instance method of [<code>Vector</code>](#Vector)  
<a name="Vector+start"></a>

### vector.start([point]) ⇒ <code>this</code> \| <code>Point</code>
The start point

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| [point] | <code>Point</code> | 

<a name="Vector+end"></a>

### vector.end([point]) ⇒ <code>this</code> \| <code>Point</code>
The end point

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| [point] | <code>Point</code> | 

<a name="Vector+length"></a>

### vector.length([length]) ⇒ <code>this</code> \| <code>Number</code>
The length of the vector. Resets the end point.

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| [length] | <code>Number</code> | 

<a name="Vector+angle"></a>

### vector.angle([angle]) ⇒ <code>this</code> \| <code>Number</code>
The angle from the start point to the end point. Resets the end point

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| [angle] | <code>Number</code> | 

<a name="Vector+offset"></a>

### vector.offset([point]) ⇒ <code>this</code> \| <code>Point</code>
The x and y difference represented as a point

**Kind**: instance method of [<code>Vector</code>](#Vector)  

| Param | Type |
| --- | --- |
| [point] | <code>Point</code> | 

<a name="Vector.isValid"></a>

### Vector.isValid(value) ⇒ <code>boolean</code>
