/**
|
|
||||||
* Convert locations to and from convenient short codes.
|
|
||||||
*
|
|
||||||
* Open Location Codes are short, ~10 character codes that can be used instead of street
|
|
||||||
* addresses. The codes can be generated and decoded offline, and use a reduced character set that
|
|
||||||
* minimises the chance of codes including words.
|
|
||||||
*
|
|
||||||
* This provides both object and static methods.
|
|
||||||
*
|
|
||||||
* Create an object with:
|
|
||||||
* OpenLocationCode code = new OpenLocationCode("7JVW52GR+2V");
|
|
||||||
* OpenLocationCode code = new OpenLocationCode("52GR+2V");
|
|
||||||
* OpenLocationCode code = new OpenLocationCode(27.175063, 78.042188);
|
|
||||||
* OpenLocationCode code = new OpenLocationCode(27.175063, 78.042188, 11);
|
|
||||||
*
|
|
||||||
* Once you have a code object, you can apply the other methods to it, such as to shorten:
|
|
||||||
* code.shorten(27.176, 78.05)
|
|
||||||
*
|
|
||||||
* Recover the nearest match (if the code was a short code):
|
|
||||||
* code.recover(27.176, 78.05)
|
|
||||||
*
|
|
||||||
* Or decode a code into its coordinates, returning a CodeArea object.
|
|
||||||
* code.decode()
