Class LocationInfoResponse

java.lang.Object

net.degreedays.api.Response

net.degreedays.api.data.LocationInfoResponse

All Implemented Interfaces:

java.io.Serializable

public final class LocationInfoResponse
extends Response
implements java.io.Serializable

Contains the location/station-related info returned in response to a LocationInfoRequest.

This mirrors LocationDataResponse, except it doesn't actually contain any data (i.e. no DataSets).

Since:

1.1

Instances of this class are immutable. You can safely reuse them and call them from multiple threads at once.

Method Detail

stationId

public java.lang.String stationId()

Returns the non-null, non-empty canonical ID of the weather station or combination of weather stations that would be used to generate data for an equivalent LocationDataResponse.

If the Location in the LocationInfoRequest was a StationIdLocation, this method will simply return the canonical form of that weather station's ID. We say "canonical" because it's possible for a station ID to be expressed in more than one way, like upper case or lower case. The canonical form of the station ID is the form that you should display in a UI or store in a database if appropriate.

If the Location in the LocationInfoRequest was a GeographicLocation, then:

• If the data for an equivalent LocationDataResponse would be calculated using temperature data from a single station (the usual case), this method will return the canonical form of that station's ID.
• If the data for an equivalent LocationDataResponse would be calculated using temperature data combined from multiple stations (something that the API might optionally start doing at some point in the future), this method will return the ID of a "virtual station" that represents the specific combination of weather stations used.

Either way, the station ID returned by this method can be used to fetch data from the same station(s) that would have been used to generate data in response to an equivalent LocationDataRequest. Typically you would use this to get the station ID to best represent a GeographicLocation, and then use that ID in LocationDataRequests going forward.

targetLongLat

public LongLat targetLongLat()

Returns the non-null LongLat object that specifies the geographic position of the Location from the LocationInfoRequest that led to this response.

If the Location from the request was a PostalCodeLocation, this will return the LongLat that the API determined to be the central point of that postal code.

If the Location from the request was a StationIdLocation, this will return the LongLat of that station (also accessible through getSources()).

If the Location from the request was a LongLatLocation, this will simply return the LongLat that was originally specified. (Bear in mind that the longitude and latitude may have been rounded slightly between the request and the response. Such rounding would only introduce very small differences that would be insignificant as far as the real-world position is concerned, but it's worth bearing this in mind in case you are comparing for equality the returned LongLat with the LongLat from the request. The two positions will be close, but they might not be equal.)

getSources

public Source[] getSources()

Returns the non-null, non-empty array of source(s) (essentially weather stations) that would be used to generate data for an equivalent LocationDataResponse.

At the time of writing there will only be one source for any given response (so getSources()[0] is the way to get it)... But at some point we might start combining data from multiple sources to satisfy requests for data from geographic locations. If we do add this feature, it will be optional, and disabled by default, so the behaviour of your system won't change unless you want it to.

The returned array can be modified freely without affecting the immutability of this LocationInfoResponse or the arrays returned by past, concurrent, or future calls to this method.

equals

public boolean equals(java.lang.Object o)

Returns true if o is a LocationInfoResponse with equal values for everything apart from the metadata() (which is not considered in the equality test).

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overridden to ensure consistency with equals.

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Returns a non-null, non-empty string representation of this object for logging and debugging purposes.

The exact details of the representation are unspecified and subject to change.

Overrides:

toString in class java.lang.Object
