Member Function Documentation

Coord_map clipper::Coord_grid::coord_map

(

)

const [inline]

convert to Coord_map

Returns:

The non-integer coordinate.

Coord_frac clipper::Coord_grid::coord_frac

(

const Grid_sampling &

g

)

const [inline]

convert to Coord_frac using given Grid_sampling

Fractional coordinate is not normalised onto range 0..1

Parameters:

g	The grid concerned

Returns:

The fractional coordinate

Coord_grid clipper::Coord_grid::unit

(

const Grid_sampling &

g

)

const [inline]

reduce to unit box: (0..nu-1, 0..nv-1, 0..nw-1)

Parameters:

g	The grid concerned

Returns:

The transformed coordinate.

const Coord_grid & clipper::Coord_grid::next

(

const Grid &

g

)

[inline]

increment in storage order (see index())

guaranteed to increment index(g) by 1

The grid coordinate is incremented efficiently in a manner which is exaclty equivalent to increasing index() by 1 in a zero based grid.

Parameters:

g	The grid with which this increment is synchronised.

const Coord_grid & clipper::Coord_grid::next

(

const Grid_range &

g

)

[inline]

increment in storage order (see index())

guaranteed to increment index(g) by 1

The grid coordinate is incremented efficiently in a manner which is exaclty equivalent to increasing index() by 1 in a non-zero based grid.

Parameters:

g	The grid with which this increment is synchronised.

bool clipper::Coord_grid::last

(

const Grid &

g

)

const [inline]

test if done in storage order (see index())

Test whether this coordinate has been incremented using next() beyond the end of the specified zero based grid.

Parameters:

g	The grid concerned.

bool clipper::Coord_grid::last

(

const Grid_range &

g

)

const [inline]

test if done in storage order (see index())

Test whether this coordinate has been incremented using next() beyond the end of the specified non-zero based grid.

Parameters:

g	The grid concerned.

int clipper::Coord_grid::index

(

const Grid &

g

)

const [inline]

grid indexing operator

Return the index in a 1-d array corresponding to this coordinate for a zero based grid.

Parameters:

g	The grid concerned.

Returns:

The corresponding index.

void clipper::Coord_grid::deindex	(	const Grid &	g,
		const int &	index
	)		[inline]

grid deindexing operator

Return the coordinate corresponding to a given index in a zero based grid.

Parameters:

g	The grid concerned.

Returns:

The corresponding coordinate.

String clipper::Coord_grid::format

(

)

const

return formatted String representation

Returns:

The formatted text string

Reimplemented from clipper::Vec3< int >.
