OpenLocationCode (JOpt Java Core 7.5.0-rc8 API)

java.lang.Object
- com.dna.jopt.member.unit.converter.openlocation.OpenLocationCode

```
public final class OpenLocationCode
extends Object
```
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()
