Chapter 17: CORBA/IDL Code Generation and Reverse Engineering

Anything you change using this window will set the default for all classes, attributes, operations, and so on.

You can also set the code−generation properties for a single class, attribute, operation, or other model element. To do so, open the specification window for the model element and select the CORBA tab. On this tab, you can change the properties that apply to that particular type of model element. In the following sections, we'll examine the CORBA code−generation properties.

Project Properties

Project properties are the CORBA code−generation properties that apply to the whole project rather than to any specific model element, such as a class or relationship.

The options in this section include things like the default directory to use when generating code and the maximum number of errors that can occur during code generation. Each of the project properties is listed in Table 17.1 along with its purpose and default value.

Table 17.1: CORBA Code−Generation Project Properties

You can also set these properties through the Tools → CORBA → Project Specification menu item, as shown on the following page.

Chapter 17: CORBA/IDL Code Generation and Reverse Engineering

It does not matter whether you set the properties in the Tools → Options area or through the Project Specification window. Changes you make in one area will be reflected in the other.

Class Properties

Class properties are the CORBA code−generation properties that apply specifically to classes. Most of the class properties are set through the Class Specification window. There are a few properties, however, that can also be set through the Tools → Options area, as shown below:

Table 17.2 lists the CORBA class properties on the Tools → Options window, their purposes, and their default values.

Table 17.2: CORBA/IDL Code−Generation Class Properties

The properties listed above apply to all types of CORBA classes. You can, however, set additional properties for the different CORBA stereotypes supported by Rose.

When you first create a class and try to open its specification window, Rose will prompt you for the type of class to create:

In the Stereotype field, select from the following: Interface, CORBAConstant, CORBAEnum, CORBA−Exception, CORBANative, CORBAStruct, CORBATypedef, CORBAUnion, CORBAValue, or CORBACusomValue. Once you have selected a stereotype, the appropriate specification window will appear.

Interface Specification

On the interface specification window, you can set the following:

∙

Inherits From to set the parent class

∙

Attribute/Role Ordering to set the order in which attributes and roles will be generated in the code

∙

DocComment for comments that will be generated in the code

571

CORBAConstant Specification

On the constant specification window, you can set the following:

∙

Implementation Type to set the data type of the generated constant

∙

Constant Value to set the value of the generated constant

∙

DocComment for comments that will be generated in the code

CORBANative Specification

On the CORBANative specification window, you can set only the DocComment field, which is for comments that will be generated in the code.

CORBATypeDef Specification

On the typedef specification window, you can set the following:

∙

Implementation Type to set the data type of the generated typedef

∙

Array Dimensions to indicate that the typedef's declarator is an array and sets the dimensions of the array

∙

DocComment for comments that will be generated in the code

CORBAUnion Specification

On the union specification window, you can set the following:

∙

Attribute/Role Ordering to set the order in which attributes and roles will be generated in the code

∙

Switch Type to set the switch type for case statements for the union

∙
