The name of an attribute type associated to a member name.
The mapping defined by Apache SIS may change in any future version depending on standardization progress.
To protect against such changes, users are encouraged to rely on methods or constructors like
DefaultTypeName
can be instantiated by any of the following methods:
DefaultNameFactory.createTypeName(NameSpace, CharSequence)
DefaultNameFactory.toTypeName(Class)
Mapping Java classes to type names
A bidirectional mapping is defined betweenTypeName
and Java Class
.
When an UML identifier from an OGC standard exists for a given Class
,
Apache SIS uses that identifier prefixed by the "OGC"
namespace.
Note that this is not a standard practice.
A more standard practice would be to use the
data type URN standard values
(third column in the table below), but the set of data type identifiers defined by OGC is currently
small and is sometimes not an exact match.

Immutability and thread safety
This class is immutable and thus inherently thread-safe if theNameSpace
and CharSequence
arguments given to the constructor are also immutable. Subclasses shall make sure that any overridden methods
remain safe to call from multiple threads and do not change any public TypeName
state.- Since:

Constructor Details

DefaultTypeName
Constructs a type name from the given character sequence and infers automatically a Java type. The scope and name arguments are given unchanged to the super-class constructor. Then the Java type is inferred in a way that depends on the specified scope:- If the scope is
"OGC"
, then:- If the name is
"CharacterString"
,"Integer"
,"Real"
or other recognized names (see class javadoc), then the corresponding Java class is associated to this type name. - Otherwise
UnknownNameException
is thrown.
- If the name is
- Else if the scope is
"class"
, then:- If the name is accepted by
Class.forName(String)
, then that Java class is associated to this type name. - Otherwise
UnknownNameException
is thrown.
- If the name is accepted by
- Else if the scope is global, then:
- If the name is one of the names recognized in
"OGC"
scope (see above), then the corresponding class is associated to this type name. - Otherwise no Java class is associated to this type name. No exception is thrown because names in the global namespace could be anything; this constructor cannot know if the given name was wrong.
- If the name is one of the names recognized in
- Otherwise no Java class is associated to this type name, because this method cannot check the validity of names in other namespaces.
- Parameters:
scope
- the scope of this name, ornull
for a global scope.name
- the local name (nevernull
).- Throws:
UnknownNameException
- if a mapping from this name to a Java class was expected to exist (because the specified scope is "OGC" or "class") but the associated Java class cannot be found.- See Also:
- If the scope is
-
DefaultTypeName
Constructs a type name from the given character sequence and explicit Java type. The scope and name arguments are given unchanged to the super-class constructor.- Parameters:
scope
- the scope of this name, ornull
for a global scope.name
- the local name (nevernull
).javaType
- the value type to be returned bytoJavaType()
, ornull
if none.- Since:

Method Details
-
castOrCopy
Returns a SIS type name implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:- If the given object is
null
, then this method returnsnull
. - Otherwise if the given object is already an instance of
DefaultTypeName
, then it is returned unchanged. - Otherwise a new
DefaultTypeName
instance is created with the same values than the given name.
- Parameters:
object
- the object to get as a SIS implementation, ornull
if none.- Returns:
- a SIS implementation containing the values of the given object (may be the
given object itself), or
null
if the argument was null. - Since:
- 0.5
- If the given object is
-
toJavaType
Returns the Java type represented by this name. This is the type either specified explicitly at construction time or inferred from the type name.- Returns:
- the Java type (usually a
Class
) for this type name. - Since:
- 1.3
- See Also:
-
equals
Compares this type name with the specified object for equality.- Overrides:
equals
in classDefaultLocalName
- Parameters:
object
- the object to compare with this type for equality.- Returns:
true
if the given object is equal to this name.
