iterator_impl() [2/2]

C2DTransformation::iterator_impl::iterator_impl	(	const C2DBounds &	pos,
		const C2DBounds &	size )

Constructor to initialize the iterator at a certain point

Parameters

pos	current position of the iterator
size	defines the grid of the domain of the iterator as \([pos.x, size.x-1] \times [pos.y, size.y-1]\)

Member Function Documentation

advance()

void C2DTransformation::iterator_impl::advance

(

unsigned int

delta

)

fast advance the position

clone()

virtual iterator_impl * C2DTransformation::iterator_impl::clone ( ) const

pure virtual

Returns

a dynamically allocated copy of the iterator

References iterator_impl().

get_pos()

const C2DBounds & C2DTransformation::iterator_impl::get_pos

(

)

const

Returns

the cutrrent grid position of the iterator

References get_pos().

Referenced by get_pos().

get_size()

const C2DBounds & C2DTransformation::iterator_impl::get_size

(

)

const

Returns

the domain size of the underlying transformation

References get_size().

Referenced by get_size().

get_value()

const C2DFVector & C2DTransformation::iterator_impl::get_value

(

)

const

Returns

the current value of the transformation iterated over

increment()

void C2DTransformation::iterator_impl::increment

(

)

increment the position

operator==()

bool C2DTransformation::iterator_impl::operator==

(

const iterator_impl &

other

)

const

Compare the iterator to another one

Parameters

other

Returns

true if the positions are equal or both are at the end of the range

Remarks

no test is run whether both iterator belong to the same transformation

print()

void C2DTransformation::iterator_impl::print

(

std::ostream &

os

)

const

Print some information about the iteratorto an output stream, mostely used for debugging purpouses

Parameters

os
