Member Function Documentation

operator!=()

bool RVO::Vector2::operator!= ( const Vector2 &  q ) const

inline

Vector inequality.

Parameters

q	The right hand side vector

Returns

True if the lhs vector and the rhs vector are not equal. False otherwise.

operator*() [1/2]

float RVO::Vector2::operator* ( const Vector2 &  q ) const

inline

Dot product.

Parameters

q	The right hand side vector

Returns

The dot product of the lhs vector and the rhs vector.

operator*() [2/2]

Vector2 RVO::Vector2::operator* ( float  a ) const

inline

Scalar product.

Parameters

a	The right hand side scalar

Returns

The scalar product of the lhs vector and the rhs scalar.

operator*=()

Vector2& RVO::Vector2::operator*= ( float  a )

inline

The operator multiplies the vector by a scalar.

Parameters

a	The scalar

Returns

A reference to the vector.

operator+() [1/2]
