About this task
A transformation configuration
has .tc as a file name extension, and contains the information that
the transformation uses to generate the output that you expect. A
transformation configuration also contains information that is specific
to a particular type of transformation. To edit an existing transformation
configuration, in a view that shows the workspace resources, double-click
a transformation configuration file, which opens the transformation configuration
editor.
To simplify working with the
transformation configuration file, save the configuration file in
the project that contains the elements to transform.
- Depending on the view that you are working
in, complete one of the following steps:
- In the Pattern Explorer view, right-click
a transformation; then click New Configuration.
- In other views, click . If Transformation Configuration is
not a menu item, click .
- Specify the details of the configuration.
In the New Transformation
Configuration wizard,
on the Specify a Configuration
Name and Transformation page,
complete the following steps:
- In the Name field,
specify a name for the configuration.
- In the Configuration file destination field,
specify the destination for the transformation configuration file.
The destination is a relative path in your current workspace. You
can specify a fully qualified project name or folder name. If you
specify a folder in a project, you must prefix the folder name with
a forward slash (/).
- From the Transformation list,
select a transformation.
Note: To display the transformations
that are installed, but not enabled, click Show all transformations.
A transformation must be bound to a capability to appear in this list.
- In the Protocol section,
specify the modeling protocol, which is also called the design contract
management protocol (DCMP). The value that you select determines whether
to synchronize the source and target of the transformation.
- If the source model is the primary
engineering artifact, select Conceptual.
Any changes to the source model are propagated to the target model.
- If the architecture that the source
artifacts represent evolves independently from the target, select Reconciled.
Selecting this option enables the reverse transformation, which you
can use to compare the source and target, and to reconcile changes.
You might also select this option if different teams implement, develop,
or maintain the architecture.
- Click Next.
- Specify the source and target elements
for the transformation. For a list of valid source and target elements,
see the related concept topic for this transformation. On the Source and Target page,
complete the following steps:
- In the Selected source pane,
select the source element for the transformation to transform.
- In the Selected target pane,
select the destination of the transformation output. To create a new
destination for the output, click Create Target Container.
- Click Next.
- Optional: Specify which C++ elements the transformation
transforms into UML operations, and whether the transformation generates
UML associations or UML properties for member variables in a class.
These options provide you with greater control over the UML elements
that the transformation generates in the target UML model. By default,
for each class that you specify in the transformation source, the
transformation generates UML operations for C++ getter and setter
methods, default constructors and destructors, copy constructors,
and assignment operators, and creates UML associations for member
variables. On the C++ to UML Options page, complete one or more of
the following steps:
- To create UML operations, select the check boxes beside the
C++ elements to transform.
- To create UML associations for member variables, select the Generate
UML associations for C++ member variables by peeking into the model.
The transformation examines the target model and creates association
relationships for member variables that are part of an association
relationship. If a member variable is not part of a UML association,
the transformation creates a UML property.
- Click Finish. The transformation configuration
editor opens,
and the contents of the configuration are displayed.
- Optional: To generate
debugging information, on the Main page,
select the Generate a debug log check
box. The next time that you run the transformation,
the log file is generated as an XML file in the folder that you specify
in the transformation preferences. If you do not specify a location
for the log files, the transformation generates the log file in the .metadata folder
in your workspace.
The log file provides information
about the source elements, the target elements, and the rules that
the transformation applies to transform the source elements. If the
transformation transforms many elements, you might experience decreased
performance while the transformation generates the log file; therefore,
you should only generate a log file for debugging purposes.
- Optional: To
prevent new dialog boxes from opening while a transformation runs,
on the Main page,
select the Run the forward transformation silently check
box.
Running a transformation
in silent mode suppresses all dialog boxes that the transformation
generates. The transformation applies default rules and behavior,
which might generate unexpected or incorrect transformation output.
You should only run a transformation in silent mode to validate that
the transformation runs, instead of validating the transformation
output. For example, you might run a transformation in silent mode
as part of an automated task or automated test suite.
Setting the transformation to run
in silent mode overrides the file-overwrite options that you specify,
and overwrites files if necessary.
If
the UML-to-C++, or reverse, transformation is available, you can select
the Run the reverse transformation silently check
box. Specifying that the reverse transformation runs in silent mode
overrides the file overwrite options that you specify in the transformation
configuration. The transformation overwrites files if necessary.
- Optional: To
display the errors that occurred when the transformation ran, on the Main page,
select the Open the Report dialog box when the transformation
is complete check
box. Selecting this check box displays only the generated errors.
The same information is also written to the error log, which you can
view by clicking .
To display the warnings that occurred when the transformation
ran, select the Show warnings in the Report dialog
box check
box.
- Optional: Specify documentation
about the transformation configuration. This field is useful for communicating
information about a configuration that multiple users share. On the Main page,
in the Documentation field,
specify additional information about the transformation configuration.
- Click .
