DESCRIPTION

       2D vector class used to store 2D integer vectors and points. This class is used throughout
       Inventor for arguments and return values.

METHODS

                         SbVec2s()
          Default constructor.

                         SbVec2s(const short v[2])
                         SbVec2s(short x, short y)
          Constructor given 2 components.

     int32_t             dot(const SbVec2f &v) const
          Returns dot (inner) product of vector and another vector.

     const short *       getValue() const
     void                getValue(short &x, short &y) const
          Returns vector components.

     void                negate()
          Negates each component of vector in place.

     SbVec2s &           setValue(const short v[2])
     SbVec2s &           setValue(short x, short y)
          Sets vector components.

     short &             operator [](int i)
     const short &       operator [](int i)
          Accesses indexed component of vector.

     SbVec2s &           operator *=(int d)
     SbVec2s &           operator *=(double d)
     SbVec2s &           operator /=(int d)
     SbVec2s &           operator /=(double d)
          Component-wise scalar multiplication and division operators.

     SbVec2s &           operator +=(const SbVec2s &u)
     SbVec2s &           operator -=(const SbVec2s &u)
          Component-wise vector addition and subtraction operators.

     SbVec2s             operator -() const
          Nondestructive unary negation — returns a new vector.

     SbVec2s             operator *(const SbVec2s &v, int d)
     SbVec2s             operator *(const SbVec2s &v, double d)
     SbVec2s             operator *(int d, const SbVec2s &v)
     SbVec2s             operator *(double d, const SbVec2s &v)
     SbVec2s             operator /(const SbVec2s &v, int d)
     SbVec2s             operator /(const SbVec2s &v, double d)
          Component-wise binary scalar multiplication and division operators.

     SbVec2s             operator +(const SbVec2s &v1, const SbVec2s &v2)
     SbVec2s             operator -(const SbVec2s &v1, const SbVec2s &v2)
          Component-wise binary vector addition and subtraction operators.

     int                 operator ==(const SbVec2s &v1, const SbVec2s &v2)
     int                 operator !=(const SbVec2s &v1, const SbVec2s &v2)
          Equality comparison operators.
