Class TypedArrays

    java.lang.Object
      com.google.gwt.typedarrays.shared.TypedArrays

    public class TypedArrays

extends java.lang.Object

Factory class for various typed arrays. Behavior of all other methods is undefined if `isSupported()` returns false.

In client code, the various types are implemented by JavaScriptObjects, so you cannot reliable use instanceof checks on any of the returned implementations.

    public static Uint8ClampedArray createUint8ClampedArray(ArrayBuffer buffer,
                                                            int byteOffset,
                                                            int length)

  Create a `Uint8ClampedArray` instance on `buffer`, starting at `byteOffset` into the buffer, continuing for `length` elements.

  Parameters:
    `buffer` - underlying `ArrayBuffer`
    `byteOffset` - byte offset from the start of `buffer`
    `length` - number of elements in the resulting array
  Returns:
    an `Uint8ClampedArray` instance

### createUint8ClampedArray

    public static Uint8ClampedArray createUint8ClampedArray(int length)

  Create a `Uint8ClampedArray` instance of `length` elements, backed by a new `ArrayBuffer`.

  Parameters:
    `length` - size of array
  Returns:
    a `Uint8ClampedArray` instance

### isSupported

    public static boolean isSupported()

  Check if the current environment supports typed arrays. Behavior of the various `createXXX` methods is undefined if this method returns `false`, but will typically throw some exception.

  Returns:
    true if typed arrays are support.
