public class DefaultTemporalCRS
extends AbstractCRS
implements TemporalCRS

A 1-dimensional coordinate reference system used for the recording of time. The Apache SIS implementation provides the following methods in addition to the OGC/ISO properties:

• to­Date(double) for converting a temporal position to a Date.
• to­Value(Date) for converting a Date to a temporal position.

Used with datum type: Temporal.
Used with coordinate system type: Time.

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself), the coordinate system and the datum instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.

Since:

0.4

Constructor Detail

DefaultTemporalCRS

public DefaultTemporalCRS(Map<String,?> properties,
                          TemporalDatum datum,
                          TimeCS cs)

Creates a coordinate reference system from the given properties, datum and coordinate system. The properties given in argument follow the same rules than for the super-class constructor. The following table is a reminder of main (not all) properties:

Recognized properties (non exhaustive list)

Property name	Value type	Returned by
"name"	ReferenceIdentifier or String	AbstractIdentifiedObject.getName()
"alias"	GenericName or Char­Sequence (optionally as array)	AbstractIdentifiedObject.getAlias()
"identifiers"	ReferenceIdentifier (optionally as array)	AbstractIdentifiedObject.getIdentifiers()
"remarks"	InternationalString or String	AbstractIdentifiedObject.getRemarks()
"domainOfValidity"	Extent	AbstractReferenceSystem.getDomainOfValidity()
"scope"	InternationalString or String	AbstractReferenceSystem.getScope()

Parameters:

properties - the properties to be given to the coordinate reference system.

datum - the datum.

cs - the coordinate system.

Geodetic­Object­Factory.create­Temporal­CRS(Map, Temporal­Datum, Time­CS)

DefaultTemporalCRS

protected DefaultTemporalCRS(TemporalCRS crs)

Constructs a new coordinate reference system with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a SIS one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API.

This constructor performs a shallow copy, i.e. the properties are not cloned.

Parameters:

crs - the coordinate reference system to copy.

See Also:

cast­Or­Copy(Temporal­CRS)

Method Detail

castOrCopy

public static DefaultTemporalCRS castOrCopy(TemporalCRS object)

Returns a SIS coordinate reference system implementation with the same values than the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.

Parameters:

object - the object to get as a SIS implementation, or null if none.

Returns:

a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

getInterface

public Class<? extends TemporalCRS> getInterface()

Returns the GeoAPI interface implemented by this class. The SIS implementation returns Temporal­CRS.class.

Note for implementors: Subclasses usually do not need to override this method since GeoAPI does not define Temporal­CRS sub-interface. Overriding possibility is left mostly for implementors who wish to extend GeoAPI with their own set of interfaces.

Overrides:

get­Interface in class Abstract­CRS

Returns:

Temporal­CRS.class or a user-defined sub-interface.

getDatum

public TemporalDatum getDatum()

Returns the datum.

Specified by:

get­Datum in interface Single­CRS

Specified by:

get­Datum in interface Temporal­CRS

Returns:

the datum.

getCoordinateSystem

public TimeCS getCoordinateSystem()

Returns the coordinate system.

Specified by:

get­Coordinate­System in interface Coordinate­Reference­System

Specified by:

get­Coordinate­System in interface Single­CRS

Specified by:

get­Coordinate­System in interface Temporal­CRS

Overrides:

get­Coordinate­System in class Abstract­CRS

Returns:

the coordinate system.

forConvention

public DefaultTemporalCRS forConvention(AxesConvention convention)

Returns a coordinate reference system equivalent to this one but with axes rearranged according the given convention. If this CRS is already compatible with the given convention, then this method returns this.

Overrides:

for­Convention in class Abstract­CRS

Parameters:

convention - the axes convention for which a coordinate reference system is desired.

Returns:

a coordinate reference system compatible with the given convention (may be this).

See Also:

Abstract­CS.for­Convention(Axes­Convention)

toDate

public Date toDate(double value)

Convert the given value into a Date object. If the given value is Na­N or infinite, then this method returns null.

This method is the converse of to­Value(Date).

Parameters:

value - a value in this axis unit.

Returns:

the value as a date, or null if the given value is NaN or infinite.

toValue

public double toValue(Date time)

Convert the given date into a value in this axis unit. If the given time is null, then this method returns Na­N.

This method is the converse of to­Date(double).

Parameters:

time - the value as a date, or null.

Returns:

the value in this axis unit, or Na­N if the given time is null.

formatTo

protected String formatTo(Formatter formatter)

Formats this CRS as a Well Known Text Time­CRS[…] element.

Compatibility note: Time­CRS is defined in the WKT 2 specification only.

Overrides:

format­To in class Abstract­CRS

Parameters:

formatter - the formatter where to format the inner content of this WKT element.

Returns:

"Time­CRS".
