Enclosing class:

SimpleCRS

public static class SimpleCRS.Temporal
extends SimpleCRS
implements TemporalCRS, TimeCS, TemporalDatum

A TemporalCRS specialization of SimpleCRS with its own datum.

In order to keep the model simpler, this temporal CRS is also its own datum. Merging the CRS and datum interfaces is usually not a recommended practice since many temporal CRS can have the same datum. However, this particular class takes this approach because the geoapi-examples module is only a demonstration of how GeoAPI can be implemented in a few simple cases. More complex applications are encouraged to store the datum in a separated object.

Constructor	Description
Temporal(Citation authority, String name, Date origin, CoordinateSystemAxis axis)	Creates a new CRS for the given name, datum and axes.

Method Summary

Modifier and Type	Method	Description
TimeCS	getCoordinateSystem()	Returns the coordinate system, which is represented directly by this implementation class since it does not distinguish CS and CRS.
TemporalDatum	getDatum()	Returns the datum, which shall be temporal.
Date	getOrigin()	Returns the date and time origin of this temporal datum.

Constructor Details

Temporal

public Temporal(Citation authority,
 String name,
 Date origin,
 CoordinateSystemAxis axis)

Creates a new CRS for the given name, datum and axes.

Parameters:

authority - organization responsible for definition of the name, or null.

name - the name of the new CRS.

origin - the value to be returned by getOrigin().

axis - the axis to be returned by SimpleCRS.getAxis(int).

Method Details

getCoordinateSystem

public TimeCS getCoordinateSystem()

Returns the coordinate system, which is represented directly by this implementation class since it does not distinguish CS and CRS.

Specified by:

getCoordinateSystem in interface CoordinateReferenceSystem

Specified by:

getCoordinateSystem in interface SingleCRS

Specified by:

getCoordinateSystem in interface TemporalCRS

Overrides:

getCoordinateSystem in class SimpleCRS

Returns:

the coordinate system.

getDatum

public TemporalDatum getDatum()

Returns the datum, which shall be temporal.

Specified by:

getDatum in interface SingleCRS

Specified by:

getDatum in interface TemporalCRS

Returns:

the datum.

getOrigin

public Date getOrigin()

Returns the date and time origin of this temporal datum. The units can be obtained by getAxis(0).getUnit().

Specified by:

getOrigin in interface TemporalDatum

Returns:

the date and time origin of this temporal datum.
