Class JsArrayNumber

java.lang.Object
com.google.gwt.core.client.JavaScriptObject
com.google.gwt.core.client.JsArrayNumber
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]; }-* /;

  • Method Details

    • 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 Development Mode and unpredictable behavior may occur in Production Mode.
      Parameters:
      index - the index to be retrieved
      Returns:
      the value at the given index

    • 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(double value)
      Pushes the given number onto the end of the array.

    • 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

    • setLength

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

    • shift

      public final double shift()
      Shifts the first value off the array.
      Returns:
      the shifted value

    • unshift

      public final void unshift(double value)
      Shifts a value onto the beginning of the array.
      Parameters:
      value - the value to the stored
