是否有一个术语用于集合类型的链式处理，尤其是列表、集合和映射？

Question

考虑 scala 中的基本集合处理顺序：

val a = ((1 to 50)
  .map(_ * 4)
  .filter( _ <= 170)
  .filter(_.toString.length == 2)
  .filter (_ % 20 == 0)
  .zipWithIndex
  .map{ case(x,n) => s"Result[$n]=$x"}
  .mkString("  .. "))

  a: String = Result[0]=20  .. Result[1]=40  .. Result[2]=60  .. Result[3]=80

我想 term/way 概括地描述一系列的集合处理步骤。有这样的名词吗？

Answer 1

Martin Fowler 使用术语 collection pipeline:

Collection pipelines are a programming pattern where you organize some computation as a sequence of operations which compose by taking a collection as output of one operation and feeding it into the next. (Common operations are filter, map, and reduce.)

IMO，这是 pipe and filter 软件架构模式的特例：

Pipe and Filter is a simple architectural style that connects a number of components that process a stream of data, each connected to the next component in the processing pipeline via a Pipe.
