描述----------Description----------
A virtual base class representing components that can consume data from a Producer, and yield data to the user or other Consumer instances. A Consumer typically transforms records from one form to another. Producer and Consumer instances are associated with each other through the stream function or using the connect function.
一个虚基类的组件，可以消耗Producer和产量数据给用户的数据或其他Consumer实例。一个Consumer通常从一种形式转换记录。 Producer和Consumer实例相互关联，通过stream功能或使用connect功能。
方法----------Methods----------
Methods defined on this class include:
在这个类中定义的方法包括：
stream signature(x = "Consumer", ...): see
流signature(x = "Consumer", ...)：见
show signature(object = "Consumer"): Display the
显示signature(object = "Consumer")：显示
领域----------Fields----------
inputPipe: Object of class Streamer, representing the Producer or Consumer connected up-stream to
inputPipe：Streamer，代表类Producer或Consumer连接，流对象
.records: Object of classlist which is used as a
.records：list类对象被用作
The Consumer class inherits the fields yieldSize, verbose and inUse from the virtual Streamer class. Please refer to the Streamer class for more details.
Consumer类继承的领域yieldSize，verbose和inUse从虚拟Streamer类。更多详细信息，请参阅Streamer类。
基于类的方法----------Class-Based Methods----------
initialize(..., inputPipe): A method to initialize the fields of the Consumer class.
initialize(..., inputPipe)：一个方法来初始化Consumer类领域。
inputPipe: An object of class Streamer connected up-stream to it. The class could be a Consumer or Producer
inputPipe：一个类的对象Streamer连接流。类可能是一个Consumer或Producer
...: Additonal arguments, currently unused.
...：产生额外的参数，目前尚未使用。
verbose: A logical(1) instance indicating whether methods invoked on the class should be reported to the
verbose：logical(1)实例，指示是否调用类的方法，应上报
reset(): Return the result of delegating
reset()：返回下放的结果
yield(): Return the result of delegating
yield()：返回下放的结果
inputs(): Return a character vector
inputs()：返回一个character向量
status{}: Reports the status of the Consumer class. A list of the status of the length of the object in the .records field, the classes connected to the inputPipe field and the status of the fields
status{}：报告Consumer类的状态。一个list状态.records领域对象的长度，连接类的inputPipe领域和该领域的地位
.fill(): An internal method that fills the .records
.fill()：一个内部方法，填补了.records
.add(input): An internal method that appends the value passed to the argument
.add(input)：一个内部方法，追加值传递的参数
