All references that are marked are added to a zero count stack, where it’s determined whether they’re available to be emptied. Figure 2-5 demonstrates that while the reference ‘obj’ may be set to null, secondaryObj has not been, and therefore the memory consumed from the Objects instantiation cannot yet be reclaimed. Figure 2-5. Instantiation and memory location referenced via secondaryObj; Design patterns, whether creational, behavioral, or structural, pass references for delegation and modification.
These steps move toward accomplishing a specific goal. Each scenario has a clear beginning and ending, and there is always only one goal per use case. In short, a use case is a story that explains the system. Depending on the agency for which you work, getting your hands on the statement of work (SOW) is the optimal way to determine your use case. A SOW is a document that details the project requirements and defines the agency’s work activities. If you don’t have access to a SOW, ask the designer to detail the steps their comp demonstrates, as they understand them, and then walk through the comp with them.
It also gives you immediate feedback from the editor in an effort to prevent type errors early on. Practicing optimal implementation of design patterns in ActionScript 3 requires you to choose the most appropriate types to bind to the expressions and variables among each pattern’s collaborative objects. Using types that are overly specific reduces the pattern’s reusability, leading to tightly coupling. However, falling back on an overly generalized type requires careful collaboration and attention to your system and its parts.
