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.

                                                            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.
