Constructor & Destructor Documentation

VectorUnary()

template<typename E , typename F >

CDPL::Math::VectorUnary< E, F >::VectorUnary ( const ExpressionType &  e )

inline

Constructs the expression-template node wrapping e.

Parameters

e	The vector expression to wrap.

Member Function Documentation

getSize()

template<typename E , typename F >

SizeType CDPL::Math::VectorUnary< E, F >::getSize ( ) const

inline

Returns the wrapped expression's size.

Returns

The element count.

operator()()

template<typename E , typename F >

ConstReference CDPL::Math::VectorUnary< E, F >::operator() ( SizeType  i ) const

inline

Applies the unary functor to element i of the wrapped expression and returns the result.

Parameters

i	The zero-based element index.

Returns

The element value as transformed by the functor.

operator[]()

template<typename E , typename F >

ConstReference CDPL::Math::VectorUnary< E, F >::operator[] ( SizeType  i ) const

inline
