Founder mutations are a class of disease-causing genetic mutations, each derived from its own ancestral "founder" in whom the mutation originated.
创始者突变是一类引起疾病的基因突变，每一种都源自其自身祖先的“创始者”。
I remembered the saying we learnt in class about not judging (判断) a book by its cover.
我想起了我们在课堂上学过的一句话：不要以貌取人。
What if the code we have uses a concrete class in its implementation?
如果我们拥有的代码在执行中使用一个具体的类该怎么办？
A class and an interface differ: a class can have an actual instance of its type, whereas an interface must have at least one class to implement it.
一个类和一个接口不同：一个类可以有它形态的真实实例，然而一个接口必须至少有一个类来实现它。
If the class already USES a superclass, the newly generated superclass will have that class as its superclass, maintaining the class hierarchy.
如果这个类已经使用了一个超类，那么新生成的超类将把该类作为它的超类，并会保持类的层次结构。
No decisions are made by the class, as its sole function is to create a report.
这个类没有制定任何决策，它的惟一功能就是创建一个报告。
When you're writing code, think about the contract — the particular bit you're writing will expose to its client, whether it's a method, a class, or a group of interacting classes.
当编写代码时，应考虑到这个契约——您将要编写的特定内容都将暴露给它的客户机，无论此内容是一个方法、一个类，还是一个与类交互的组。
For example, a class loader could first load a class explicitly and then load all of its referenced classes implicitly.
例如，类装入器可能先显式地装入一个类，然后再隐式地装入它引用的所有类。
However, this case — where a class manages its own memory — is one of the very few situations where explicitly nulling objects that are no longer needed is a good idea.
但是这种情况——由类管理其自己的内存——是一种非常少见的情况，即显式地消除不再需要的对象是一个好主意。
With a metadata-based subaspect, when a join point in a class changes its characteristics only the annotation for the join point needs to be changed.
利用基于元数据的子方面，当类中的连接点改变其特性时，只有这个连接点的注释需要改变。
Consider a thread-safe container class - a data structure that guarantees thread safety to its clients.
可以考虑使用一个线程安全容器类—一个保证用户操作线程安全的数据结构。
Just as an MC is a special-purpose object, its definition is a special-purpose class which defines the structure and behavior of its instances.
正如MC是专用对象一样，其定义也是专用类，用于定义其实例的结构和行为。
If the chosen library is not available at runtime, the RegexpPlugin API tries to create a compiler using its class name.
如果所选的库在运行时不可用，则RegexpPluginapi会尝试用它的类名创建一个编译器。
When a Struts action takes place, its action class passes data to the property broker.
当一个Struts行为发生以后，它的行为类就会将数据传递给这个属性代理。
Importantly, the SerializationClass class has a reference to its defining class loader, and so it cannot be completely dereferenced either.
重要的是，serializationclass类有一个到其定义类装入器的引用，所以它也不可能完整地取消引用。
Note that the GenericDaoHibernateImpl class defines only one constructor that takes a domain class as its argument.
注意，GenericDaoHibernateImpl类仅定义一个构造函数，该构造函数接受域类作为其参数。
In other words, Factory Method lets a class defer the instantiation to its subclasses.
换句话说，Factory方法令一个类实例化到其子类。
Every class loader has a parent class loader, which delegates the searching and loading of a class to its parent (parent-first delegation) before it attempts to load the class itself.
每个类加载器有一个父类加载器，在尝试加载类本身时，先将类搜索和类加载委托给它的父加载器，即父加载器优先（parent-first）委托。
set_curr_task: This function is called when a task changes its scheduling class or changes its task group.
set_curr_task：当任务修改其调度类或修改其任务组时，将调用这个函数。
It explicitly delineates its output key as a Text object and its value as an IntWritable, which is a Hadoop-specific class that is essentially an integer.
它显式地将其输出键指定为一个Text对象，将其值指定为一个Int Writable，这是一个hadoop特定类，实质上是一个整数。
In Python, no such formal declaration exists, and the "abstract" ness of a class is simply a recommendation by the class developer to its users.
在Python中并没有该正规声明，而类的“抽象”只是类的开发者给其用户的建议。
It's also the identifier for the loaded class itself — you can have multiple copies of the same binary class loaded in a JVM, each with its own class instance.
它还是已装入类本身的标识—对于装入到JVM的同一个二进制类，可以有多个副本，每个副本都有其自己的Class实例。
Figure 12 is a UML class diagram of the AcronymListEditor class depicting its relationship to the Eclipse parent classes as well as a validator class that can validate input.
图12是AcronymListEditor类的一个UM l类图，描绘了该类与Eclipse父类以及一个可以验证输入的检验器类之间的关系。
As it turns out, lookup on a class follows its MRO before it looks in its instantiating metaclass.
当解析发生时，在查找实例化元类之前，会先遵循它的MRO对类进行查找。
Notice from the tag in Listing 1 that its <filter-class> child specifies a class named org.acegisecurity.util.FilterToBeanProxy.
请注意清单1中的标记，它的
For instance a user can trace an XML document to see all the nodes and attributes, or trace a custom class to see its structure and properties.
比如，用户可以跟踪一个XML文档，看到所有的节点和数值，或者跟踪某个定制的类，以看到它的结构和属性。
You may only extend a single class and inherit its method implementations.
您可能只扩展一个类并继承其方法实现。
Sometimes, it is very difficult to make a class thread-safe without compromising its functionality, ease of use, or performance.
有时，要在不影响类的功能、易用性或性能的情况下使类成为线程安全的是很困难的。
Super class mapping support; attribute to column mapping defined in a super class should be available for its child class.
超类映射支持；超类中定义的属性到列的映射应该可用于它的子类。
Super class mapping support; attribute to column mapping defined in a super class should be available for its child class.
超类映射支持；超类中定义的属性到列的映射应该可用于它的子类。
