This paper investigates how implementation variants of design patterns impact on the retrieval effectiveness of a design pattern recovery tool. Specifically, we first defined several implementation variants of Adapter and Observer design patterns, by introducing constraints or relaxations on their canonical form. Then, we analyze the relationship between the complexity of these definitions and the precision and time needed by a design pattern recovery process we proposed in the past. To this end, we apply ePAD, an Eclipse plug-in for design pattern recovery, to eight software systems. We show that there exist interesting issues about the relationship between the complexity of the defined variants and the precision and time needed to recover their instances.

Abstract
This paper investigates how implementation variants of design patterns impact on the retrieval effectiveness of a design pattern recovery tool. Specifically, we first defined several implementation variants of Adapter and Observer design patterns, by introducing constraints or relaxations on their canonical form. Then, we analyze the relationship between the complexity of these definitions and the precision and time needed by a design pattern recovery process we proposed in the past. To this end, we apply ePAD, an Eclipse plug-in for design pattern recovery, to eight software systems. We show that there exist interesting issues about the relationship between the complexity of the defined variants and the precision and time needed to recover their instances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
