  • Method Details

    • x

      public double x()
      Specified by:
      x in interface Vector2DType
      Specified by:
      x in interface VectorReadable2DType
      Returns:
      The value of the x attribute

    • y

      public double y()
      Specified by:
      y in interface Vector2DType
      Specified by:
      y in interface VectorReadable2DType
      Returns:
      The value of the y attribute

    • withX

      public final Vector2D withX(double value)
      Copy the current immutable object by setting a value for the x attribute. A value strict bits equality used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for x
      Returns:
      A modified copy of the this object

    • withY

      public final Vector2D withY(double value)
      Copy the current immutable object by setting a value for the y attribute. A value strict bits equality used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for y
      Returns:
      A modified copy of the this object

    • equals

      public boolean equals(Object another)
      This instance is equal to all instances of Vector2D that have equal attribute values.
      Overrides:
      equals in class Object
      Returns:
      true if this is equal to another instance

    • hashCode

      public int hashCode()
      Computes a hash code from attributes: x, y.
      Overrides:
      hashCode in class Object
      Returns:
      hashCode value

    • toString

      public String toString()
      Prints the immutable value Vector2D with attribute values.
      Overrides:
      toString in class Object
      Returns:
      A string representation of the value

    • of

      public static Vector2D of(double x, double y)
      Construct a new immutable Vector2D instance.
      Parameters:
      x - The value for the x attribute
      y - The value for the y attribute
      Returns:
      An immutable Vector2D instance

    • copyOf

      public static Vector2D copyOf(Vector2DType instance)
      Creates an immutable copy of a Vector2DType value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
      Parameters:
      instance - The instance to copy
      Returns:
      A copied immutable Vector2D instance

    • builder

      public static Vector2D.Builder builder()
      Creates a builder for Vector2D. 
       Vector2D.builder()
    .setX(double) // required x
    .setY(double) // required y
    .build();
      Returns:
      A new Vector2D builder
