Delegates are type-safe reference types that provide similar functions to pointers in other languages. PowerDesigner models delegates as classes with a stereotype of <<Delegate>> with a single operation code-named "<signature>". The visibility, name, comment, flags and attributes are specified on the class object whereas the return-type and parameters are specified on the operation.
A type-level (class or struct) delegate is modeled either as an operation bearing the <<Delegate>> stereotype, or as a namespace-level delegate in which the class representing the delegate is inner to the enclosing type.
For information about creating and working with classes, see Classes (OOM).
