Method Detail

from

public static <T extends V,V> Value<V> from(GeoCoordinates coordinates,
                                            Optional<T> optional)

Creates a Value from a key and an Optional. The resulting value contains the value from the Optional if a value is present. Value is empty if the Optional is empty.

Parameters:

coordinates - the score.

optional - the optional. May be empty but never null.

Returns:

the Value.

fromNullable

public static <T extends V,V> Value<V> fromNullable(GeoCoordinates coordinates,
                                                    T value)

Creates a Value from a coordinates and value. The resulting value contains the value if the value is not null.

Parameters:

coordinates - the coordinates.

value - the value. May be null.

Returns:

the Value.

just

public static <T extends V,V> GeoValue<V> just(double longitude,
                                               double latitude,
                                               T value)

Creates a GeoValue from a key and value. The resulting value contains the value.

Parameters:

longitude - the longitude coordinate according to WGS84.

latitude - the latitude coordinate according to WGS84.

value - the value. Must not be null.

Returns:

the GeoValue

just

public static <T extends V,V> GeoValue<V> just(GeoCoordinates coordinates,
                                               T value)

Creates a GeoValue from a key and value. The resulting value contains the value.

Parameters:

coordinates - the coordinates.

value - the value. Must not be null.

Returns:

the GeoValue.

getCoordinates

public GeoCoordinates getCoordinates()

getLongitude

public double getLongitude()

Returns:

the longitude if this instance has a Value.hasValue().

Throws:

NoSuchElementException - if the value is not present.

getLatitude

public double getLatitude()

Returns:

the latitude if this instance has a Value.hasValue().

Throws:

NoSuchElementException - if the value is not present.

equals

public boolean equals(Object o)

Overrides:

equals in class Value<V>

hashCode

public int hashCode()

Overrides:

hashCode in class Value<V>

toString

public String toString()

Overrides:

toString in class Value<V>

map

public <R> GeoValue<R> map(Function<? super V,? extends R> mapper)

Returns a GeoValue consisting of the results of applying the given function to the value of this element. Mapping is performed only if a value is present.

Overrides:

map in class Value<V>

Type Parameters:

R - element type of the new GeoValue.

Parameters:

mapper - a stateless function to apply to each element.

Returns:

the new GeoValue.

mapCoordinates

public GeoValue<V> mapCoordinates(Function<? super GeoCoordinates,? extends GeoCoordinates> mapper)

Returns a GeoValue consisting of the results of applying the given function to the GeoCoordinates of this element. Mapping is performed only if a value is present.

Parameters:

mapper - a stateless function to apply to each element.

Returns:

the new GeoValue.
