Class Geohashed

         |
        Geohashed

A cache of en- and decoded geohashes of one precision.

Instance Methods

__init__(self, precision, ndigits=None)
New Geohashed cache.

__len__(self)
Return the number of unigue geohashes (int).

clear(self)
Clear the en- and decoded cache.

decoded(self, geohash, encoded=False)
Get and cache the (lat, lon) for geohash, see decode.

encoded(self, lat, lon, decoded=False)
Get and cache the geohash for (lat, lon), see encode.

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __sizeof__, __str__, __subclasshook__

Properties
	len2 Return 2-tuple `(lencoded, ldecoded)` with the `len`gths of the `en-` and `decoded` cache.
	ndigits Get the rounding (`int` or `None`).
	precision Get the `precision` (`int`).
Inherited from `object`: `__class__`

Method Details

init (self, precision, ndigits=None)
(Constructor)

New Geohashed cache.

Arguments:

precision - The geohash encoded length (int, 1..12).
ndigits - Optional number of digits to round lat and lon to cache keys (int, typically ndigits=precision) or None for no rounding.

Overrides: object.__init__

decoded (self, geohash, encoded=False)

Get and cache the (lat, lon) for geohash, see decode.

Arguments:

encoded - If True, cache the result as encoded.

Returns:

The (lat, lon) pair for geohash.

encoded (self, lat, lon, decoded=False)

Get and cache the geohash for (lat, lon), see encode.

Arguments:

decoded - If True, cache the result as decoded.

Returns:

The geohash for pair (lat, lon).

Property Details

len2

Return 2-tuple (lencoded, ldecoded) with the lengths of the en- and decoded cache.

Get method:: len2(self) - Return 2-tuple (lencoded, ldecoded) with the lengths of the en- and decoded cache.
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.

ndigits

Get the rounding (int or None).

Get method:: ndigits(self) - Get the rounding (int or None).
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.

precision

Get the precision (int).

Get method:: precision(self) - Get the precision (int).
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.
