General Rules

• 'package' visibility will be translated into 'Friend'
• 'abstract' will be translated into 'MustInherit' or 'MustOverride'
• 'final' will be translated into 'NotInheritable' or 'NotOverridable'
• 'static' will be translated into 'Shared'

The following keys for tagged value pairs are supported when the value has been set to 'true' within the appropriate context:

• 'Shadows'
• 'Overridable'
• 'Protected Friend'

Modelling Element Rules

Classes

• Uses the standard UML 'Class'
• Supports single inheritance only
• Protected Friend visibility is determined by setting the tagged value 'Protected Friend' to 'true'. Everything else will use the checked visibility radio button.
• Classes with abstract operations must also be declared 'abstract'

Interfaces

• Uses the standard UML 'Interface'
• Interface identifiers must start with the 'I' character
• Interface operations must be 'Public' and cannot be 'Shared'
• Interfaces cannot have attributes or navigable opposite association ends

Modules

• Uses the standard UML 'Class' with the << Module>> stereotype
• Modules cannot be 'abstract' or 'final'
• Modules cannot participate in generalizations or specifications
• Modules cannot be an inner classifier or have an inner classifier
• Modules cannot have a 'Protected' or 'Protected Friend' member

Structures

• Uses the standard UML 'Class' with the << Structure>> stereotype
• Structures must have at least one member that is non-static (shared) and is either an attribute, a navigable opposite association end, or an operation with the stereotype <<Event>>.
• Structures cannot have a 'Protected' or 'Protected Friend' member
• Structures cannot have an attribute or navigable opposite association end with an initialized value

Enums

• Uses the standard UML 'Class' with the << Enum>> stereotype
• By default it generates an Enum as type 'Integer'
• Enums do not participate in generalizations or specifications
• Enums cannot have navigable opposite association ends, operations, or inner classifiers
• Other Enum types are supported by using the tagged value key 'type' with one of the following values
  • 'Short'
  • 'Byte'
  • 'Integer'
  • 'Long'
  Anything else will default to 'Integer'.

Operations

• Operations support the following tagged values:
  • 'Protected Friend'
  • 'Shadows'
  • 'Overridable'
• Operations with no return parameter (returning 'void') are generated as 'Sub'
• Operations with a return parameter are generated as 'Function'

Operation's Parameters

• Parameter type 'in' is translated as 'ByVal', everything else is 'ByRef'
• The type 'ParamArray' is supported by using the stereotype << ParamArray>> with a parameter
• A 'ParamArray' parameter must be the last parameter
• A 'ParamArray' parameter must be of type 'in' or 'ByVal'

Attribute & Association Ends

• Supports the tagged value 'Protected Friend'

Visual Basic Properties

• Properties are supported with <<Property>> stereotyped operations
• There are 3 type of stereotypes available:
  • ‘Property’ will generate ‘Get’ and ‘Set’ inside the Property block
  • ‘ReadOnly Property’ will generate only ‘Get’ inside the Property block
  • ‘WriteOnly Property’ will generate only ‘Set’ inside the Property block
• If no attribute is set in ‘accessed attribute’, it will by default generate an attribute with same type as the Property return type with the name set to ‘m_operation_name’.

Visual Basic Events

• VB Events are supported by using <<Event>> stereotypes with operations
