凭借SourceMate提供的“Override/ImplementMethods”特性，开发者可以浏览子类树并从中选择想要覆写的方法。
Our "Override/Implement Methods" feature allows developers to browse through a tree of subclasses and choose methods from those subclasses they'd like to override.
默认度是1，这就是为什么在继承树中一些子类会丢失的原因。
The default degree is 1, and this is why some grandchildren are missed in the inheritance tree.
从一个已存在系统中发现整个的继承树结构是相当有用的，因为它能向您揭露在树中什么是顶级类以及什么是子类。
Discovering the entire inheritance tree structure from an existing system is particularly useful, because it helps you uncover what the top-level class is and what subclasses are in the tree.
备用方法(不在这里研究)是结果只将SimpleNode节点提供给解析树，而不是它的子类。
The alternative (not explored here) is for productions to contribute only SimpleNode nodes to the parse tree and not subclasses thereof.
实际上，将IntBetween3And 17作为int的一个子类型是很有意义的，至少从表面上是如此，而不管继承树是否与此匹配。
In fact, it makes sense to call IntBetween3And17 a subtype of int, at least informally, whether or not the inheritance tree matches that.
树以tree类表示，这个类是Basetree的子类。
The tree class represents a tree and is a subclass of Basetree.
澳洲土著人有两种重要的食物：一种是铁树目裸子类棕桐树的果子，另一种是又大又有营养的山药。
Two important aboriginal foods are the fruit of the cycad palm and a large nutritious yam.
一个本体可以抽象为一个树状结构，概念由类与子类构成，类与子类之间的关系是树中的边。
Ontology can be viewed as a tree structure. Concepts comprise of class and subclass, the relationships between which are tree's edges.

答：四个核心类船型不会去改动它，但正如你看到的日本驱逐舰和即将加入的苏联驱逐舰，我们包括通过引入分线在科技树中加入的“子类船型”。
The four core classes aren't going anywhere but, as you've likely seen with Japanese destroyers and incoming Soviet destroyers, we're including "subclasses" by introducing splits in the tech tree.
