Constructor Detail

• Coordinate

  Coordinate(Number xCoord, Number yCoord)

  Creates a Coordinate with given xCoord and yCoord.

  Parameters:

  xCoord - The x coordinate.

  yCoord - The y coordinate.

Method Detail

• getXCoord

   final Double getXCoord()

  X coordinate.

• getYCoord

   final Double getYCoord()

  Y coordinate.

• plus

   final Coordinate plus(Coordinate other)

  Returns a new coordinate object containing added xCoord and yCoord.

  Parameters:

  other - Coordinate to add.

• minus

   final Coordinate minus(Coordinate other)

  Returns a new coordinate object containing subtracted xCoord and yCoord.

  Parameters:

  other - Coordinate to subtract.

• times

   final Coordinate times(Number factor)

  Returns a new coordinate object containing multiplied Coordinate with factor.

  Parameters:

  factor - factor to multiply with.

• div

   final Coordinate div(Number denominator)

  Returns a new coordinate object containing divided Coordinate by denominator.

  Parameters:

  denominator - denominator to divide by.

• rotated

   final Coordinate rotated(Number angle, Coordinate center)

  Rotates Coordinate by angle degrees around center point.

  With

  • Angle t,

  • Center point Z

  • Coordinate P

  cos(phi) -sin(phi) * Px - Zx + Zx = cos(phi)*(Px-Zx) - sin(phi)*(Py-Zy) + Zx

  Py - Zy sin(phi)*(Px-Zx) + cos(phi)*(Py-Zy) + Zy

• rotated

   final Coordinate rotated(Double angle)

  Rotates coordinate by angle degrees around point (0,0).

  With

  • Angle t,

  • Center point Z

  • Coordinate P

  cos(phi) -sin(phi) * Px - Zx + Zx = cos(phi)*(Px-Zx) - sin(phi)*(Py-Zy) + Zx

  Py - Zy sin(phi)*(Px-Zx) + cos(phi)*(Py-Zy) + Zy

• toString

   String toString()

  Prints xCoord and yCoord as String.

• equals

   Boolean equals(Object other)

  Compares coordinate to another Object.

• hashCode

   Integer hashCode()

  HashCode for this object.
