10. Briefly explain containment. |
|
|
|
|
|
|
|
|
Containment is similar to composition, except that the containing object is not responsible for the life of the contained object. Thus, an object can create another object for its exclusive use but can't pass the object to another for the other's use. This is the case with collections in which a containing object creates an object, populates it with data from a graphical user interface, and then passes that object to a collection. A collection object contains objects. |

1. What advantages and disadvantages must you consider when deciding whether to acquire third-party controls? |
|
|
|
|
|
|
|
|
The advantages are decreased development time (and therefore reduced development costs) and reuse over many projects. Buying a third-party control is like buying canned labor: the third-party vendor has put its labor force's time and energy into that control so that you don't have to put your time and energy into reproducing the same code. What's more, you can reuse that canned time and energy over many projects, thus receiving increasing returns on investment over time. |
|
|
|
|
|
|
|
|
The disadvantages are that many controls have been poorly documented, rendering the controls almost useless. Other controls are awkward or require too many |
