JsArray (Google Web Toolkit Javadoc)

java.lang.Object
- com.google.gwt.core.client.JavaScriptObject
- - com.google.gwt.core.client.JsArray<T>

Type Parameters:
T - the concrete type of object contained in this array
```
public class JsArray<T extends JavaScriptObject>
extends JavaScriptObject
```
A simple wrapper around a homogeneous native array of JavaScriptObject values. This class may not be directly instantiated, and can only be returned from a native method. For example, native JsArray getNativeArray() /*-{ return [ { x: 0, y: 1}, { x: 2, y: 3}, { x: 4, y: 5}, ]; }-* /;

- Method Detail
  - get
```
public final T get(int index)
```
    Gets the object at a given index.
    
    Parameters:
    index - the index to be retrieved
    
    Returns:
    the object at the given index, or null if none exists
  - join
```
public final java.lang.String join()
```
    Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
  - join
```
public final java.lang.String join(java.lang.String separator)
```
    Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
  - length
```
public final int length()
```
    Gets the length of the array.
    
    Returns:
    the array length
  - push
```
public final void push(T value)
```
    Pushes the given value onto the end of the array.
  - set
```
public final void set(int index,
       T value)
```
    Sets the object value at a given index. If the index is out of bounds, the value will still be set. The array's length will be updated to encompass the bounds implied by the added object.
    
    Parameters:
    index - the index to be set
    value - the object to be stored
  - setLength
```
public final void setLength(int newLength)
```
    Reset the length of the array.
    
    Parameters:
    newLength - the new length of the array
  - shift
```
public final T shift()
```
    Shifts the first value off the array.
    
    Returns:
    the shifted value
  - unshift
```
public final void unshift(T value)
```
    Shifts a value onto the beginning of the array.
    
    Parameters:
    value - the value to the stored
