The UML elements that the transformation generates depends on the
characteristics of the Java™ code that you specify as the source
of the transformation. If the transformation cannot transform a Java element,
it ignores the element.
Java classes
The following table lists how
the transformation transforms Java classes into UML classes.

and the interface |

how the transformation transforms Java interfaces into UML interfaces.

| Extends a superinterface |
Generalization relationship between the interface and
the superinterface |
| Static import (J2SE 5.0) |
Usage relationship between the interface and the imported
element |
Java enumerations
The following table lists
how the transformation transforms Java enumerations into UML enumerations.
| Properties of the Java enumeration |
Properties of the UML enumeration |
|---|
| Package |
Enumeration in a package with the same name as the Java package |
| Name |
Enumeration with the same name |
| Visibility |
Same visibility as the source Java enumeration |
| Specifies the final keyword |
isLeaf property set to true |
| Specifies the abstract keyword |
isAbstract property set to true |
| Static import (J2SE 5.0) |
Usage relationship between the interface and the imported
element |
Java attributes in Java classes or interfaces
The
following table lists how the transformation transforms Java attributes
located in Java classes or interfaces.
| Properties of the Java attribute |
Properties of the UML attribute |
|---|
| Name |
Property with the same name |
| Visibility |
Same visibility as the source Java property |
| Specifies the static keyword |
isStatic property set to true |
| Specifies the final keyword |
isLeaf property set to true |
| Specifies the abstract keyword |
isAbstract property set to true |
| Type (non-collection types) |
Type property set to an existing primitive type, existing
UML element in the model, or a reference to the Java type |
| Type (collection types) |
Type property is null; set the collection properties
according to the Transformation
of Java collection
properties table |
| Generic type (J2SE 5.0) |
Type property set to the type in the Java class
or interface; set the collection properties according to the Transformation
of Java collection
properties table |
Java properties in Java enumerations
The transformation
transforms a Java property in an enumeration into a UML EnumerationLiteral
that has the same name.
Java methods in Java classes and interfaces
The
following table lists how the transformation transforms Java methods
in classes and interfaces into UML operations.
| Properties of the Java method |
Properties of the UML operation |
|---|
| Name |
Operation with the same name |
| Visibility |
Same visibility as the source Java method |
| Specifies the static keyword |
isStatic property set to true |
| Specifies the final keyword |
isLeaf property set to true |
| Parameters |
Parameter with same properties as the Java parameter;
the transformation generates the parameters in the same order that they appear
in the Java method If the Java method contains a return parameter,
the transformation generates the return parameter of the operation before
it generates the other parameters for the operation. See the Java method
parameters table.
|
| Specifies a throws statement and one
or more throwable objects |
RaisedException property of the UML operation specifies
the exception classes in the throws statement Tip: To
view the properties of the UML operation, in the Project Explorer view, right-click
the UML operation; then click UML Properties.
|
Java method parameters
The following table
lists how the transformation transforms Java method parameters.
| Java parameter |
UML parameter |
|---|
| Variable (J2SE 5.0) |
Multiplicity set to * |
| Input |
Direction set to in |
| Return |
Direction set to return; the generated parameter is
named ReturnParameter |
The following table lists how the transformation generates
the properties that are common to the types of parameters listed above.
| Properties of the Java method parameter |
Properties of the UML parameter |
|---|
| Name |
Parameter with the same name |
| Type (non-collection types) |
Type property set to an existing primitive type, or
an element in the model, or to a reference to a Java type |
| Type (collection types) |
Type property set to null; collection properties set
according to the Transformation
of Java collection
properties table |
| Generic type (J2SE 5.0) |
Type property set to the type in the Java class
or interface; set the collection properties according to the Transformation
of Java collection
properties table |
UML multiplicity for properties and parameters
The
following table lists how the transformation sets the multiplicity property
for Java properties
and parameters types that it transforms.
| Java type |
UML multiplicity |
|---|
| Attribute; for example, String x |
0..1 |
| Array with dimensions; for example, String[3]
x |
N, where N>1 |
| Array without dimensions; for example, String[]
x |
0..* |
| Java collection type specified in the transformation
configuration |
