                      LatLon2PsxyIter

Iterate and convert for points with optional loop-back and copies.

Instance Methods

__init__(self, points, loop=0, base=None, wrap=True, radius=None, dedup=False, name='latlon')
New LatLon2PsxyIter iterator.

__getitem__(self, index)
Get the point(s) at the given index or slice.

enumerate(self, closed=False, copies=False)
Iterate and yield each point as a 2-tuple (index, Point3Tuple).

iterate(self, closed=False, copies=False)
Iterate the points starting at index loop and yield each as a Point3Tuple(x, y, ll).

Method Details

init (self, points, loop=0, base=None, wrap=True, radius=None, dedup=False, name=`'latlon'`)
(Constructor)

New LatLon2PsxyIter iterator.

Arguments:

points - Iterable or list, sequence, set, tuple, etc. (LatLon[]).
loop - Number of loop-back points, also initial enumerate and iterate index (non-negative int).
base - Optional points instance for type checking (any).
wrap - If True, wrap or normalize the enum-/iterated points (bool).
radius - Mean earth radius (meter) for conversion from degrees to meter (or radians if radius=1).
dedup - Skip duplicate points (bool).
name - Optional name (str).

Raises:

PointsError - Insufficient number of points.
TypeError - Some points are not base-compatible.

Overrides: object.__init__

Note: The LatLon latitude is considered the pseudo-y and longitude the pseudo-x coordinate, like LatLon2psxy.

getitem (self, index)
(Indexing operator)

Get the point(s) at the given index or slice.

Raises:

IndexError - Invalid index, beyond loop.

Overrides: _BaseIter.__getitem__

enumerate (self, closed=False, copies=False)

Iterate and yield each point as a 2-tuple (index, Point3Tuple).

Arguments:

closed - Loop back to the first point(s), de-dup'ed (bool).
copies - Save a copy of all points (bool).

Raises:

PointsError - Insufficient number of points or using closed=True without loop-back.
TypeError - Some points are not base-compatible.

Overrides: _BaseIter.enumerate

iterate (self, closed=False, copies=False)

Iterate the points starting at index loop and yield each as a Point3Tuple(x, y, ll).

Arguments:

closed - Loop back to the first point(s), de-dup'ed (bool).
copies - Save a copy of all points (bool).

Raises:

PointsError - Insufficient number of points or using closed=True without loop-back.
TypeError - Some points are not base-compatible.

Overrides: _BaseIter.iterate
