## 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.
