Association (Role) Properties

Role properties are the CORBA properties that deal with associations. Using these properties, you can control the code generated for the associations.

Because roles are implemented as attributes, many of the code−generation properties are identical for an attribute and a role. Two properties, however, are unique to roles: GenerateForwardReference and BoundedRoleType.

There are three places to set role properties. To set them for all associations, select Tools → Options, then click the CORBA tab and select Role from the drop−down list box. To set them for only one association, select the CORBA tab on the association's standard specification window, or open the CORBA specification

window for the association and edit the properties there.

Table 17.6 lists the code−generation properties for associations, their purposes, and their default values.

Table 17.6: CORBA Code−Generation Association Properties

Property	Purpose	Default
ArrayDimensions	Sets the array dimensions used for an exception,	<blank>
	struct, or union when the BoundedRoleType
	association property is set to Array
CaseSpecifier	Sets the label of the case statement of a union	<blank>
GenerateForwardReference	Controls whether a referenced interface is included	#include (False)
	with an #include statement or a forward reference
IsReadOnly	Controls whether the generated attribute is read only	False
Order	Sets the order of attributes and roles generated	<blank>
BoundedRoleType	If the relationship multiplicity is greater than one,	Sequence
	controls whether an array or sequence is used for the
	generated attribute

These properties can also be set using the CORBA Attribute Specification window:

Dependency Properties

The dependency properties are the CORBA properties that control how dependency relationships are generated.
