ABSTRACT
As a further demonstration of composition, we make an initial foray into designing and implementing a general container class. A general container is different from an array because it can hold different types. A general container is different from a cell array because all objects must descend from the same parent. For example, a general cShape
container can hold both
cStar
and cDiamond
objects because they both use
cShape
as a parent. A container is also different from a cell array because a container has a structure-like interface. The interface makes a container behave a lot like an object array. Rather than looping over each element in the container, clients can use vector syntax. Often the loop still exists; however, it is now hidden behind the container’s interface.
