businessMethod

Description This is the businessObject meta-model's 'method' which is used on an internal-class and its derivatives (like business-object).

The businessObject's method is derived from the Java 'method', enhancing it in the following ways:

the method and its parameters can have constraints
collections can be given a definition of the objects they contain
the implementation is moved to the implementation class (although this can be prevented by the 'implement-in-base' flag).
This method is distinct from the business method because it does not have the notion of "exposing to users".

14.29.1	Property 'returnElementType'
14.29.2	Property 'implementInBase'
14.29.3	Property 'uid'

14.29.1 Property 'returnElementType'

*Description*	The return-element-type defines the types of objects in a collection, and is used to specify test values. The value specified for return-element-type can be either the concrete class, a base class or an interface implemented by objects in the collection.
*Type*	String
*Default*	\null

14.29.2 Property 'implementInBase'

*Description*	Normally methods at the business object level may have an implementation in the implementation class. This can be prevented by setting the 'implement-in-base' flag: this forces the implementation into the base class and prevents the user providing an overriding implementation. If this is true, then the implementation text - if appropriate - must be provided in the specification, and this implementation will be included in the base class. If no implementation text is provided, then a null implementation is generated in the base class.
*Type*	boolean
*Default*	false

14.29.3 Property 'uid'

*Description*	The 'uid' is a Unique IDentifier for a methods in the business object model (and derivatives like J2EE). The 'uid' uniquely identifies the method, even if the name or signature of the method changes. This will normally be generated by the modelling tool; if not, it can be entered manually (but make sure it is unique!).
*Type*	String
