Detailed Description

Iterator to iterator over the grid points of the supported range

Todo:

this iterator shouldn't be here, but should be a separate class not bound to the 2D transformation

Constructor & Destructor Documentation

C2DTransformation::const_iterator::const_iterator

(

)

Standard constructor

Remarks

constructed like this the iterator is not usable.

C2DTransformation::const_iterator::const_iterator

(

iterator_impl *

holder

)

Constructor to be initialized with "a real implementation"

Parameters

holder

is the implementation that does all the real work and depends on the transformation

C2DTransformation::const_iterator::const_iterator

(

const const_iterator &

other

)

Copy Constructor impelemnts the deep copy of the holder The pointer to the holder is not shared but cloned.

Member Function Documentation

const C2DBounds& C2DTransformation::const_iterator::get_size

(

)

const

const C2DFVector& C2DTransformation::const_iterator::operator*

(

)

const

Returns

the current value of the transformation

const_iterator& C2DTransformation::const_iterator::operator++

(

)

Prefix increment

const_iterator C2DTransformation::const_iterator::operator++

(

int

)

Postfix increment

const_iterator& C2DTransformation::const_iterator::operator+=

(

unsigned int

delta

)

Advance a certain amount of steps. This implementation will ususlly be fatser than the generic std::advance function, since for forward_iterators std::advance calls "++" delta times

Parameters

delta

const C2DFVector* C2DTransformation::const_iterator::operator->

(

)

const

Returns

the pointer version of the current value of the transformation

const_iterator& C2DTransformation::const_iterator::operator=

(

const const_iterator &

other

)

Assignment operator implemnts the deep copy of the holder The pointer to the holder is not shared but cloned.

const C2DBounds& C2DTransformation::const_iterator::pos

(

)

const

void C2DTransformation::const_iterator::print

(

std::ostream &

os

)

const

Print the current position and value to an output stream

Parameters

os

Referenced by operator<<().
