Examples of com.google.gwt.core.client.JsArrayNumber

com.google.gwt.core.client.JsArrayNumber
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]; }-* /;

  public JavaScriptObject wrap(int[] type) {
    if (!GWT.isScript()) {
      if (type == null) {
        return null;
      }
      JsArrayNumber wrapperArray =  JavaScriptObject.createArray().cast();
      for (int i = 0; i < type.length; i++) {
        wrapperArray.set(i, type[i]);
      }
      return wrapperArray;
    } else {
      return reinterpretCast(type);
