All Implemented Interfaces:

Serializable, Formattable, Deprecable, Lenient­Comparable, Printable, Datum, Identified­Object

public class DefaultParametricDatum
extends AbstractDatum

Defines the origin of a parametric coordinate reference system.

Creating new parametric datum instances

New instances can be created either directly by specifying all information to a factory method (choices 2 and 3 below), or indirectly by specifying the identifier of an entry in a database (choices 1 below).

1. Create a Parametric­Datum from an identifier in a database by invoking Datum­Authority­Factory.create­Parametric­Datum(String).
2. Create a Parametric­Datum by invoking the Datum­Factory.create­Parametric­Datum(…) method, (implemented for example by Geodetic­Object­Factory).
3. Create a Default­Parametric­Datum by invoking the constructor.

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself) 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:

0.7

Constructor Details

DefaultParametricDatum

public DefaultParametricDatum(Map<String,?> properties)

Creates a parametric datum from the given properties. The properties map is given unchanged to 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"	Identifier or String	AbstractIdentifiedObject.getName()
"alias"	GenericName or Char­Sequence (optionally as array)	AbstractIdentifiedObject.getAlias()
"identifiers"	Identifier (optionally as array)	AbstractIdentifiedObject.getIdentifiers()
"domains"	DefaultObjectDomain (optionally as array)	AbstractIdentifiedObject.getDomains()
"remarks"	InternationalString or String	AbstractIdentifiedObject.getRemarks()
"anchorPoint"	InternationalString or String	AbstractDatum.getAnchorDefinition()
"anchorEpoch"	Temporal	AbstractDatum.getAnchorEpoch()

Parameters:

properties - the properties to be given to the identified object.

• Geodetic­Object­Factory.create­Parametric­Datum(Map)

DefaultParametricDatum

protected DefaultParametricDatum(DefaultParametricDatum datum)

Creates a new datum with the same values as 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.

Warning: in a future SIS version, the parameter type may be changed to org.opengis.referencing.datum.Parametric­Datum. This change is pending GeoAPI revision.

Parameters:

datum - the datum to copy.

Method Details

formatTo

protected String formatTo(Formatter formatter)

Formats this datum as a Well Known Text Parametric­Datum[…] element.

Compatibility note

Parametric­Datum is defined in the WKT 2 specification only. Apache SIS accepts this type as members of datum ensembles, but this is not valid WKT according ISO 19162:2019.

Overrides:

format­To in class Abstract­Datum

Parameters:

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

Returns:

"PDatum" or "Parametric­Datum". May also be "Member" if this datum is inside a WKT Ensemble[…] element.
