public class JsArrayNumber
extends JavaScriptObject

A simple wrapper around a homogeneous native array of numeric values. All native JavaScript numeric values are implicitly double-precision, so only double values may be set and retrieved. This class may not be directly instantiated, and can only be returned from a native method. For example, native JsArrayNumber getNativeArray() /*-{ return [1.1, 2.2, 3.3]; }-* /;

protected JsArrayNumber()
Method Detail

get

public final double get(int index)
Gets the value at a given index. If an undefined or non-numeric value exists at the given index, a type-conversion error will occur in hosted mode and unpredictable behavior may occur in web mode.

Parameters:
index - the index to be retrieved
Returns:
the value at the given index

length

public final int length()
Gets the length of the array.

Returns:
the array length

set

public final void set(int index,
                      double value)
Sets the value 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 value.

Parameters:
index - the index to be set
value - the value to be stored
