<p>Add new page</p> <p><b>New page</b></p><div>In [[object-oriented programming]], the &#039;&#039;&#039;aggregation pattern&#039;&#039;&#039; refers to an object that owns or is responsible for an [[array]] of [[object (object-oriented programming)|object]]s and defines special behavior for that particular type of array.<br /> <br /> ==Features==<br /> The aggregation pattern is useful in situations where code gets more complicated over time and certain characteristics need to be guaranteed for a particular array of objects.<br /> <br /> ===Encapsulation===<br /> The aggregation pattern provides a way to encapsulate an array of objects inside another object with an interface for that particular type of array.<br /> <br /> ===Effort===<br /> The aggregation pattern requires time and effort to write wrapper methods for all of the common array operations. In most cases, however, not all of the array operations are needed.<br /> <br /> ===Performance===<br /> The aggregation pattern provides a way to optimize algorithms when performing common array operations, such as sorting or searching the array. For example, the array primitives built into LabVIEW do [[Wikipedia:linear search|linear search]] on an array because LabVIEW has no way of knowing whether a given array is sorted or not. If the array is always sorted, a [[Wikipedia:binary search|binary search]] is much faster. <br /> <br /> ==External links==<br /> * [[Wikipedia:Aggregate pattern|Aggregate pattern]] on Wikipedia<br /> * [https://forums.ni.com/t5/LabVIEW-Development-Best/Aggregation-Pattern/ta-p/3491073 Applying Common Object-Oriented Design Patterns to LabVIEW: Aggregation Pattern] by Elijah Kerry<br /> <br /> [[Category:Object-Oriented Programming]]<br /> [[Category:Object-Oriented Design Pattern]]<br /> [[Category:Design patterns]]</div>
