描述----------Description----------
The “downLogs” class is a simplified container class that can hold multiple objects of class “downLog”. Its specific purpose is to hold a population of down logs that are either generated synthetically as part of a simulation, or a collection from field measurements. The constructor of the same name has several different forms corresponding
“downLogs”类是一个简单的容器类，它可以容纳多个类的对象“downLog”。其具体目的是为了保持人口的下降是综合部分的模拟，从实地测量或收集的log。相同名称的构造函数有几种不同的形式对应
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("downLogs", ...); however, as in the other classes within this package, constructors have been written to simplify the process. The downLogs constructor should therefore be used
可以创建对象通过调用的形式new("downLogs", ...);然而，在这个包内的其他类，构造函数被写入到简化的过程。 downLogs构造函数，因此应使用
插槽----------Slots----------
Please see the virtual base class, “StemContainer”, for additional slots definitions.
请参阅虚基类，“StemContainer”，额外的插槽的定义。
logs: Object of class "list": This holds the
logs：类的对象"list"：持有
Please note that at the present time this class only partially meets the requirements of a true “container class” in object oriented programming. This is because it does not as yet have methods for object deletion, editing, or addition to the list of down logs. Because the statistics and bounding box are tied to the collection, a caution is in order regarding changing in any way the objects within your R code. The best way to handle this is to simply extract the list from the object, do whatever editing has to be done to it, then use the constructor below to make a new object. Then everything will be correctly represented within the object.
请注意，在目前这个类只部分地满足了面向对象编程中真正的“容器类”的要求。这是因为它不尚未有对象删除，编辑，或添加到列表中的倒木的方法。由于统计和边框都与一个谨慎的收集，是为了在您的R代码中的对象以任何方式改变。最好的方式来处理，这是简单的提取列表中的对象，不要做任何编辑，然后使用下面的构造函数，使一个新的对象。然后，一切都将被正确地表示对象的内部。
