描述----------Description----------

This is a class that represents a reference to a set of strings in the libstree library.  The underlying data structure can be thought of as a character vector in which the order is not meaningful. The set is a collection of strings.  In R, we can  compute its length and index its elements via the [ operator.  This is convenient, for example, when sampling from the set.  However because the order is  not respected when constructing the set from a character vector, one cannot treat this as a regular character vector in  R.
这是一个类，它代表了一组字符串在libstree库的参考。底层数据结构可以被看作是在该命令是没有意义的字符向量。集是一个字符串的集合。在R，我们可以计算出它的长度和索引它的元素，通过[运营商。这是很方便，例如，当从一套采样。然而，因为订单是不尊重的建设从特征向量集时，可以不治疗作为常规字符向量在R


类的对象----------Objects from the Class----------

The preferred way to create a StringSet is via the generic StringSet function.
创建一个StringSet的首选方式是通过通用的StringSet功能。


插槽----------Slots----------




ref: Object of class "externalptr".  This is a reference to the internal C-level object that represents the string set in libstree.
ref类"externalptr"的对象。这是一个内部的C级对象代表在libstree设置字符串的引用。
