  • Field Details

    • EMPTY

      public static final Rect[] EMPTY
      Empty array of Rect's.

    • x

      public int x
      The X position of the rectangle.

    • y

      public int y
      The Y position of the rectangle.

    • cx

      public int cx
      The width of the rectangle.

    • cy

      public int cy
      The height of the rectangle.

  • Constructor Details

    • Rect

      public Rect()
      Constructor for x=y=cx=cy=0.

    • Rect

      public Rect(String string)
      Constructor from a String formatted as "x,y,cx,cy".
      Parameters:
      string - The string.
      Throws:
      IllegalArgumentException - If the string is not well formatted, holds a token that is not an integer, holds more than four tokens, or holds a value outside the codec range.

    • Rect

      public Rect(ReadTransaction trans)
      Constructor from a Transaction.
      Parameters:
      trans - The transaction.

    • Rect

      public Rect(int x, int y, int cx, int cy)
      Constructor.
      Parameters:
      x - X position.
      y - Y position.
      cx - Width.
      cy - Height.
      Throws:
      IllegalArgumentException - If any value is outside the codec range, -0x1FFFFFFF to 0x1FFFFFFF inclusive.

  • Method Details

    • isInside

      public boolean isInside(Position p)
      Checks if a position is inside.
      Parameters:
      p - The position.
      Returns:
      true if inside, false otherwise.

    • clear

      public void clear()
      Reinitializes the contents.

    • equals

      public boolean equals(Object o)
      Checks if two rectangles are equal.

      A GRect with the same four values is equal to this instance, and GRect.equals(Object) accepts a Rect in the same way, so equality is symmetric across the two types. Both classes hash as Objects.hash(x,y,cx,cy), so the hashCode contract holds across them too.

      Overrides:
      equals in class Object

    • clone

      public Rect clone()
      Clones this instance.
      Overrides:
      clone in class Object
      Returns:
      As cloned instance of GUnit.

    • toString

      public String toString()
      Formats to a string as "x,y,cx,cy".
      Overrides:
      toString in class Object

    • hashCode

      public int hashCode()
      The hash code.
      Overrides:
      hashCode in class Object

    • append

      public void append(SendTransaction trans)
      Appends the rectangle to a transaction.
      Parameters:
      trans - The transaction to append to.
