Method Detail

recordElementStatus

public void recordElementStatus(MetElement element,
                                Duration resolution,
                                Period period,
                                boolean status)

Record that a station measured or didn't measure an element at a particular resolution over a period. Used to initially specify the data holding of a station, and update it based on the results of queries.

Parameters:

element - the meteorological element

period - the period of time (which might not have an end specified)

resolution - the temporal resolution. There are useful constants in weatherData.MetDuration

status - true if the element was recorded over the period, false if it wasn't

getStationID

public String getStationID()

Get the ID that the host database uses to refer to the station.

Returns:

the ID

getRegionID

public String getRegionID()

Get the ID that the host database uses to refer to the region.

Returns:

the ID

metCatalogCardExists

public boolean metCatalogCardExists(MetElement element,
                                    Duration resolution)

Check whether a station has ever recorded an element at a particular resolution.

Returns:

true if it has recorded the element, false if it hasn't.

checkMetElementCatalog

public boolean checkMetElementCatalog(MetElement element,
                                      Duration resolution,
                                      Period period)

Check whether a station has recorded an element at a particular resolution over the period.

Returns:

true if it has recorded the element, false if it hasn't.

report

public String report(String language)

Provide a description of the station and the data it holds

Returns:

a summary of the station's metadata

getOperational

public Period getOperational()

Get the period of operation of the weather station

Returns:

the date when the station began operating, and, if it has closed, the date when it closed.

getLocation

public Location getLocation()

Get the weather station's position on the globe.

Returns:

the location of the station (latitude, longitude and altitude)

toString

public String toString()

getName

public String getName(String language)

getWeatherStation

public WeatherStation getWeatherStation(String language)

setShortestResolution

public void setShortestResolution(Duration shortestResolution)

getShortestResolution

public Duration getShortestResolution()

compareTo

public int compareTo(Object a)

Specified by:

compareTo in interface Comparable
