public interface ObjectFactory
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 can 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.
Implementations are encouraged to recognize at least the properties listed in the following table. Additional implementation-specific properties can be added. Unknown properties shall be ignored.
Property name | Value type | Value given to |
---|---|---|
"name" | ReferenceIdentifier or String |
IdentifiedObject.getName() |
"alias" | String , String[] ,
GenericName or GenericName[] |
IdentifiedObject.getAlias() |
"authority" | String or Citation |
Identifier.getAuthority() on the name |
"codespace" | String |
ReferenceIdentifier.getCodeSpace() on the name |
"version" | String |
ReferenceIdentifier.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. All localizable attributes
like "remarks"
can 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.
Departure from OGC/ISO specification:
This interface is not part of any OGC specification. It is added for uniformity, in order to provide a common base class for all referencing factories producingIdentifiedObject
instances.
