Constructor Details

LatLonFormatter

public LatLonFormatter(boolean isLat,
 boolean forDisplay)

Create a LatLonFormatter.

Parameters:

isLat - boolean true if for formatting latitudes, false for formatting longitudes.

forDisplay - boolean true if for formatting human-readable displays, false for formatting for machine-to-machine transfers

LatLonFormatter

public LatLonFormatter(boolean isLat,
 boolean forDisplay,
 LatLonFormatter.Format latLonFormat)

Create a LatLonFormatter.

Parameters:

isLat - boolean true if for formatting latitudes, false for formatting longitudes.

forDisplay - boolean true if for formatting human-readable displays, false for formatting for machine-to-machine transfers

latLonFormat - Format for this formatter, ignoring the global format value

Method Details

getGlobalLatLonFormat

public static LatLonFormatter.Format getGlobalLatLonFormat()

Get the current default format to use for formatting latitudes and longitudes.

Returns:

Format enum

setGlobalLatLonFormat

public static void setGlobalLatLonFormat(LatLonFormatter.Format globalLatLonFormat)

Set the default format to use for formatting latitudes and longitudes.

Parameters:

globalLatLonFormat - Format enum identifying the desired format

addPropertyChangeListener

public static void addPropertyChangeListener(PropertyChangeListener l)

Register a PropertyChangeListener to be informed of changes to the global format value.

Parameters:

l - PropertyChangeListener to register

removePropertyChangeListener

public static void removePropertyChangeListener(PropertyChangeListener l)

Unregister a PropertyChangeListener so it will no longer be informed of changes to the global format value.

Parameters:

l - PropertyChangeListener to unregister

format

public String format(double value)

Format the specified latitude or longitude value into a String.

Parameters:

value - double latitude or longitude in fractional degrees North or East

Returns:

String formatted according to the format, isLat, and forDisplay properties of this LatLonFormatter

format

public static String format(double latValue,
 double lonValue)

Format the specified latitude and longitude pair according to the current global format. This allows formatting in UTM format (which implicitly merges latitude and longitude together).

Parameters:

latValue - latitude in fractional degrees North

lonValue - longitude in fractional degrees East

Returns:

formatted String
