  1. Pipes & Filters Arquitectura de Sistemas de Software 2014/2015 Duarte

    Duarte João Sá Luís Cleto Miguel Marques

  2. Components • Filters Connectors • Pipes

  3. Data communication Output from one filter is conduit through a

    pipe and is the input of another filter.
  4. None
  5. None
  6. None

  7. Specialization • Pipelines: linear sequence of filters • Bounded pipes:limited

    amount of data on a pipe • Typed pipes: the data between two filters should have a well-defined type

  8. Pros • Simple composition • Reuse (any two filters can

    be hooked together) • Easily maintained and enhanced • No interactivity • No incremental display updates • Increased complexity • Requires idempotency Cons

  9. Example: Function Composition In Haskell: can be turned into effectively

    creating a filter ‘fn’ from a collection of filters and pipes
