## com.google.gwt.core.client
Class JsArray<T extends JavaScriptObject>

    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}, ]; }-* /;`

Constructor Summary
`protected` | `JsArray()`

Method Summary
`T` | `get(int index)` Gets the object at a given index.
`java.lang.String` | `join()` Convert each element of the array to a String and join them with a comma separator.
`java.lang.String` | `join(java.lang.String separator)` Convert each element of the array to a String and join them with a comma separator.
`int` | `length()` Gets the length of the array.
`void` | `push(T value)` Pushes the given value onto the end of the array.
`void` | `set(int index, T value)` Sets the object value at a given index.
`void` | `setLength(int newLength)` Reset the length of the array.
`T` | `shift()` Shifts the first value off the array.
`void` | `unshift(T value)` Shifts a value onto the beginning of the array.

Constructor Detail

### JsArray

    protected JsArray()

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
