Interface ObjectFactory

All Superinterfaces:

Factory

All Known Subinterfaces:

CoordinateOperationFactory, CRSFactory, CSFactory, DatumFactory

@Extension
public interface ObjectFactory
extends Factory

Base interface for all factories of identified objects. Factories build up complex objects from simpler objects or values. This factory allows applications to make coordinate systems, datum or coordinate reference systems that cannot be created by an authority factory. This factory is very flexible, whereas the authority factory is easier to use.

Object properties

Most factory methods expect a Map argument. The map is often (but is not required to be) a Properties instance. The map shall contains at least a "name" property. In the common case where the name is the only property, the map may be constructed with Collections.singletonMap("name", theName) where theName is an arbitrary name as free text. Additionally, implementations are encouraged to recognize at least the properties listed in the following table. More implementation-specific properties may be added as well. In any case, unknown properties will be ignored.

Property name	Value type	Value given to
"name"	Identifier or String	IdentifiedObject.getName()
"alias"	String, String[], GenericName or GenericName[]	IdentifiedObject.getAlias()
"authority"	String or Citation	Identifier.getAuthority() on the name
"version"	String	Identifier.getVersion() on the name
"identifiers"	Identifier or Identifier[]	IdentifiedObject.getIdentifiers()
"remarks"	String or InternationalString	IdentifiedObject.getRemarks()

The "name" property is mandatory. All others are optional. Additionally, all localizable attributes like "remarks" may have a language and country code suffix. For example the "remarks_fr" property stands for remarks in French and the "remarks_fr_CA" property stands for remarks in French Canadian.
