Creating an Operation

You can create an operation from the property sheet of, or in the Browser under, a class or interface.

Open the property sheet of a classifier, select the Operations tab, and click on one of the following tools:

Tool	Description
	Add a Row / Insert a Row - Enter a name and any other appropriate properties. Alternatively, right-click a class or interface in the Browser, and select New > Operation.
	Add Operations - Select existing operations to add to the classifier (see Copying an Operation From Another Classifier).
	Override Inherited Operations - Select operations inherited from a parent classifier to override (see Inheriting and Overriding Operations from Parent Classifiers).
	Add... - Click the arrow to the right of the tool and select the appropriate type of standard operation (such as constructors/destructors or initializers) from the list (see Creating a Standard Operation).
	Unimplemented Operations - Select operations to be implemented from an interface to which the current class is linked by a realization link (see Implementing Operations from an Interface).

For general information about creating objects, see Core Features Guide > Modeling with PowerDesigner > Objects.

• Copying an Operation From Another Classifier
  You can copy an operation from one classifier and add it to another. If the class already contains an operation with the same name or code as the copied operation, the copied operation is renamed.
• Inheriting and Overriding Operations from Parent Classifiers
  PowerDesigner lets you view and override operations inherited from parent classes from the child class property sheet Operations tab.
• Creating a Standard Operation
  PowerDesigner can create standard operations for your classifiers using tools on the classifier property sheet Operations tab.
• Implementing Operations from an Interface
  When you create a realization link between a class and an interface, the class must implement all the operations of the interface.
