public class AbstractReferenceSystem extends AbstractIdentifiedObject implements ReferenceSystem
Description of a spatial and temporal reference system used by a dataset. Reference systems do not necessarily use coordinates. For example a reference system could use postal codes. The specialized case of referencing by coordinates is handled by theAbstractCRS
subclass.This class inherits the name, aliases, identifiers and remarks from the parent class, and adds the following information:
- a domain of validity, the area for which the reference system is valid,
- a scope, which describes the domain of usage or limitation of usage.
InstantiationThis class is conceptually abstract, even if it is technically possible to instantiate it. Typical applications should create instances of the most specific subclass prefixed byDefault
instead.Immutability and thread safetyThis base class is immutable and thus thread-safe if the property values (not necessarily the map itself) given to the constructor are also immutable. Most SIS subclasses and related classes are immutable under similar conditions. This means that unless otherwise noted in the javadoc,ReferenceSystem
instances created using only SIS factories and static constants can be shared by many objects and passed between threads without synchronization.- Since:

AbstractReferenceSystem
public AbstractReferenceSystem(Map<String,?> properties)
Constructs a reference system from the given properties. The properties given in argument follow the same rules than for the super-class constructor. Additionally, the following properties are understood by this constructor:Recognized properties (non exhaustive list) Property name Value type Returned by "domainOfValidity" Extent
getDomainOfValidity()
"scope" String
orInternationalString
getScope()
Defined in parent class (reminder) "name" ReferenceIdentifier
orString
AbstractIdentifiedObject.getName()
"alias" GenericName
orCharSequence
(optionally as array)AbstractIdentifiedObject.getAlias()
"identifiers" ReferenceIdentifier
(optionally as array)AbstractIdentifiedObject.getIdentifiers()
"remarks" InternationalString
orString
AbstractIdentifiedObject.getRemarks()
- Parameters:
properties
- the properties to be given to this object.
-
AbstractReferenceSystem
protected AbstractReferenceSystem(ReferenceSystem object)
Constructs a new 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:
object
- the reference system to copy.

Method Detail
-
getInterface
public Class<? extends ReferenceSystem> getInterface()
Returns the GeoAPI interface implemented by this class. The default implementation returnsReferenceSystem.class
. Subclasses implementing a more specific GeoAPI interface shall override this method.- Overrides:
getInterface
in classAbstractIdentifiedObject
- Returns:
- the GeoAPI interface implemented by this class.
-
getDomainOfValidity
@Workaround(library="JDK", version="1.8") public Extent getDomainOfValidity()
Returns the region or timeframe in which this reference system is valid, ornull
if unspecified.- Specified by:
getDomainOfValidity
in interfaceReferenceSystem
- Returns:
- area or region or timeframe in which this (coordinate) reference system is valid, or
null
. - See Also:
DefaultExtent
-
getScope
public InternationalString getScope()
Returns the domain or limitations of usage, ornull
if unspecified.- Specified by:
getScope
in interfaceReferenceSystem
- Returns:
- description of domain of usage, or limitations of usage, for which this
(coordinate) reference system object is valid, or
null
.
-
equals
public boolean equals(Object object, ComparisonMode mode)
Compares this reference system with the specified object for equality. If themode
argument value isSTRICT
orBY_CONTRACT
, then all available properties are compared including the domain of validity and the scope.- Specified by:
equals
in interfaceLenientComparable
- Overrides:
equals
in classAbstractIdentifiedObject
- Parameters:
object
- the object to compare tothis
.mode
-STRICT
for performing a strict comparison, orIGNORE_METADATA
for comparing only properties relevant to coordinate transformations.- Returns:
true
if both objects are equal.- See Also:
AbstractIdentifiedObject.computeHashCode()
,Utilities.deepEquals(Object, Object, ComparisonMode)
-
computeHashCode
protected long computeHashCode()
Invoked byhashCode()
for computing the hash code when first needed. SeeAbstractIdentifiedObject.computeHashCode()
for more information.- Overrides:
computeHashCode
in classAbstractIdentifiedObject
- Returns:
- the hash code value. This value may change in any future Apache SIS version.
