public class JsArrayMixed extends JavaScriptObject
A simple wrapper around an heterogeneous native array of values. This class may not be directly instantiated, and can only be returned from a native method. For example, native JsArrayMixed getNativeArray() /*-{ return [ { x: 0, y: 1}, "apple", 12345, ]; }-* /;

      Gets the double at a given index.
      Parameters:
      index - the index to be retrieved
      Returns:
      the object at the given index coerced to number.

    • getObject

      public final <T extends JavaScriptObject> T getObject(int index)
      Gets the JavaScriptObject at a given index.
      Parameters:
      index - the index to be retrieved

      public final String getString(int index)
      Gets the String 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 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 String join(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(boolean value)
      Pushes the given boolean onto the end of the array.

    • push

      public final void push(double value)
      Pushes the given double onto the end of the array.

    • push

      public final void push(JavaScriptObject value)
      Pushes the given JavaScriptObject onto the end of the array.

    • push

      public final void push(String value)
      Pushes the given String onto the end of the array.

    • set

      public final void set(int index, boolean value)
      Sets the boolean 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 boolean to be stored

    • set

      public final void set(int index, double value)
      Sets the double 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 double to be stored

    • set

      public final void set(int index, JavaScriptObject 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 JavaScriptObject to be stored

    • set

      public final void set(int index, String value)
      Sets the String 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 String.
      Parameters:
      index - the index to be set
      value - the String to be stored

    • setLength

      public final void setLength(int newLength)
      Reset the length of the array.
      Parameters:
      newLength - the new length of the array
