Eigen::CommaInitializer

template<typename XprType>
class Eigen::CommaInitializer< XprType >

Helper class used by the comma initializer operator.

This class is internally used to implement the comma initializer feature. It is the return type of MatrixBase::operator<<, and most of the time this is the only way it is used.

MatrixBase::operator<<, CommaInitializer::finished()
XprType & finished ()

finished()

template<typename XprType >
XprType& Eigen::CommaInitializer< XprType >::finished ( )
inline
Returns
the built matrix once all its coefficients have been set. Calling finished is 100% optional. Its purpose is to write expressions like this: 
quaternion.fromRotationMatrix((Matrix3f() << axis0, axis1, axis2).finished());
