public class LocationFormat
extends TabularFormat<AbstractLocation>

Formats Location instances in a tabular format. This format assumes a monospaced font and an encoding supporting drawing box characters (e.g. UTF-8).

Example: the location identified by "32TNL83" in the military grid reference system can be represented by the following string formatted using Locale.ENGLISH:

┌─────────────────────────────────────────────────────────────┐
│ Location type:               Grid zone designator           │
│ Geographic identifier:       32TNL83                        │
│ West bound:                    580,000 m    —     9°57′00″E │
│ Representative value:          585,000 m    —    10°00′36″E │
│ East bound:                    590,000 m    —    10°04′13″E │
│ South bound:                 4,530,000 m    —    40°54′58″N │
│ Representative value:        4,535,000 m    —    40°57′42″N │
│ North bound:                 4,540,000 m    —    41°00′27″N │
│ Coordinate reference system: WGS 84 / UTM zone 32N          │
└─────────────────────────────────────────────────────────────┘

Limitations:

• The current implementation can only format features — parsing is not yet implemented.
• Location­Format, like most java.text.Format subclasses, is not thread-safe.

Constructor Detail

LocationFormat

public LocationFormat(Locale locale,
                      TimeZone timezone)

Creates a new format for the given locale. The given locale can be null or Locale.ROOT if this format shall format "unlocalized" strings.

Parameters:

locale - the locale for the new Format, or null for Locale.ROOT.

timezone - the timezone, or null for UTC.

Method Detail

getValueType

public Class<AbstractLocation> getValueType()

Returns the type of values formatted by this Format instance.

Specified by:

get­Value­Type in class Compound­Format<Abstract­Location>

Returns:

the type of values formatted by this Format instance.

format

public void format(AbstractLocation location,
                   Appendable toAppendTo)
            throws IOException

Writes a textual representation of the given location in the given stream or buffer.

Upcoming API change — generalization
in a future SIS version, the type of location parameter may be generalized to the org.opengis.referencing.gazetteer.Location interface. This change is pending GeoAPI revision.

Specified by:

format in class Compound­Format<Abstract­Location>

Parameters:

location - the location to format.

to­Append­To - where to format the location.

Throws:

IOException - if an error occurred while writing to the given appendable.

createFormat

protected Format createFormat(Class<?> valueType)

Creates the format to use for formatting a latitude, longitude or projected coordinate. This method is invoked by format(Location, Appendable) when first needed.

Overrides:

create­Format in class Compound­Format<Abstract­Location>

Parameters:

value­Type - Angle.class. Number.class or Unit.class.

Returns:

a new Angle­Format, Number­Format or Unit­Format instance depending on the argument value.

parse

public AbstractLocation parse(CharSequence text,
                              ParsePosition pos)
                       throws ParseException

Unsupported operation.

Specified by:

parse in class Compound­Format<Abstract­Location>

Parameters:

text - the character sequence for the location to parse.

pos - the position where to start the parsing.

Returns:

the parsed location, or null if the text is not recognized.

Throws:

Parse­Exception - if an error occurred while parsing the location.

clone

public LocationFormat clone()

Returns a clone of this format.

Overrides:

clone in class Tabular­Format<Abstract­Location>

Returns:

a clone of this format.
