UML | OGC Purpose | Java mapping |
---|---|---|
<<Enumeration>> |
Data type whose instances form a list of named literal values. Both the enumeration name and its literal values are declared. Enumeration means a short list of well-understood potential values within a class. | extends
java.lang.Enum |
<<CodeList>> |
A flexible enumeration useful for expressing a long list of potential values. If the elements of the list are completely known, an enumeration should be used; if the only likely values of the elements are known, a code list should be used. | extends CodeList |
<<Union>> |
Contains a list of attributes where only one of those attributes can be present at any time. | none. Create a common super-class instead. |
<<Type>> |
Class used for specification of a domain of instances (objects), together with the operations applicable to the objects. A type may have attributes and associations. | Java interface |
<<DataType>> |
A descriptor of a set of values that lack identity (independent existence and the possibility of side effects). A DataType is a class with no operations whose primary purpose is to hold the information. | Java interface |
<<Abstract>> |
A polymorphic object class that cannot be instantiated. | Java interface |
<<Interface>> |
Named set of operations that characterize the behaviour of an element.. | Java interface |
Constructor | Cast an object into an object of an other type. | A createFoo() method in a Factory interface. |
Set<DataType> |
A finite set. Each object is considered to be in the set only once. | java.util.Set |
Sequence<DataType> |
A sequence type of collection, which contains an ordered finite list of values (possibly with repeated values) of the specified data type. | Small array, or
java.util.List
if the sequence is likely to be big. |
CharacterString |
A sequence of characters. | java.lang.String
in the general case, or
java.net.URI
for reference to a file. |
Integer |
An integer number. | int if mandatory, or
java.lang.Integer
if optional. |
Double |
A double precision floating point number. | double if mandatory, or
java.lang.Double
if optional. |
Boolean |
A value specifying TRUE or FALSE. | boolean if mandatory, or
java.lang.Boolean
if optional. |
Sign |
Sign + or -. | int with value +1 ou -1 |
DateTime |
A character string as specified by ISO 19108, which comprises year, month, day and time of the day to the appropriate level of precision. | java.util.Date |
Scale |
A floating point number associated with a dimensionless unit. | double if mandatory, or
java.lang.Double
if optional. |
Length |
A floating point number associated with a linear unit. | double with some getUnit() method
(e.g. getAxisUnit() ). |
Angle |
A floating point number associated with an angular unit. | double with some getUnit() method
(e.g. getAngularUnit() ). |
Measure |
A floating point number associated with an arbitrary unit. | double with a getUnit() method. |
Record |
A structure of logically related elements. May be used as an implementation representation for features, by keeping a list of (name, value) pairs in a dictionary. This represents a generic storage structure for features. | User-defined subclass of
java.lang.Object |
RecordType |
Description of a Record structure. |
java.lang.Class |
Javadoc tag | Usage |
---|---|
@author <editor> |
The person who wrote the interface. This is not the person who
wrote the specification. The term editor may be more appropriate for
describing his task, but |
@departure <category><reason> |
Documents a departure from OGC/ISO specifications. All those tags are collected in the departures page. |
@unitof <quantity> |
The method returns a |
@todo <comment> |
Somme open issue to revisit. |
