类“bufferedTract”

描述----------Description----------
This class is a subclass of the "Tract" class. It provides, in addition to the functionality in “Tract”, the ability to create an internal buffer within the tract. This might be important, for example, when drawning a population of logs for sampling surface generation. The buffer width can be set such that no log's inclusion zone extends outside the tract. Objects of this class are also descendants of class "RasterLayer", and so share the full functionality of this class.
这个类是"Tract"类的一个子类。它规定，除在“道”的功能，能够创建一个内部缓冲区的道。这可能是重要的，例如，当溺水的用于采样表面生成的log的人口。缓冲区的宽度可设置这样没有log的列入区以外的道延伸。这个类的对象类"RasterLayer"，也后裔，所以分享的全部功能，这个类。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("bufferedTract", ...). However, this is not recommended due to the complexity of the class. Instead, use the bufferedTract constructor to create objects.
可以创建对象通过调用的形式new("bufferedTract", ...)。然而，这是不推荐的，因为类的复杂性。相反，使用bufferedTract构造函数来创建对象。
插槽----------Slots----------
In addition to those slots that are defined within the "Tract", the following are available...
在除了那些所定义的插槽内的"Tract"，以下是可用...
bufferRect: Object of class "matrix": A matrix in the form of a bounding box with row names c("x","y")
bufferRect：类的对象"matrix"：行名称中的矩阵边界框的形式c("x","y")
spBuffer: Object of class "SpatialPolygons": A SpatialPolygons representation of bufferRect via the
spBuffer：通过类的对象"SpatialPolygons"：ASpatialPolygons表示bufferRect
