## Building
./gradlew build
## Gradle dependency
See https://search.maven.org/artifact/io.github.markrileybot/geokey/
## Using
### Use built in keys to make geohashes
```java
import org.geokey.GeoKey;
// Make a geo hash key
String key = new GeoKey().setLatitude(48.669).setLongitude(-4.329).toString(); // "gbsuv7ztqzpts82uzfwq5e1bp"
// parse a geo hash key
GeoKey gk = new GeoKey("gbsuv7ztqzpts82uzfwq5e1bp");
```
### Make a special purpose K-Dimensional key
```java
public class GeoTimeKey extends KDKey {
private static final KDKeySpec spec = new KDKeySpec.Builder()
.addDim(-180, 180, 1)
.addDim(-90, 90, 1)
.addDim(0, 1L << 62, 1)
.setAlphabet(Alphabet.GEO_TIME_HASH)
.build();
public GeoTimeKey() {
super(spec);
}
public GeoTimeKey(String s) {
super(spec, s);
}
public GeoTimeKey(byte[] s) {
super(spec, s);
}
public GeoTimeKey setLatitude(double latitude) {
set(1, latitude);
return this;
}
public double getLatitude() {
return super.get(1);
}
public GeoTimeKey setLongitude(double longitude) {
set(0, longitude);
return this;
}
public double getLongitude() {
return super.get(0);
}
public GeoTimeKey setTime(long time) {
set(2, time);
return this;
}
public long getTime() {
return (long) get(2);
}
}
```
