摘要：Coming out from the process functional paradigm and using PFL ¨C a process functional
language, a generalized approach to weaving at the micro-structural level is presented. Exploiting the
application of processes and PFL reflection property, we develop a generalized weaving scheme and we
express it in the form of weaving pattern. Different specializations and extensions of weaving patterns
occurring in aspect oriented languages are discussed. Weaving patterns expressed in terms of weaving
chains provide us with the flexibility inevitable for the aspect oriented evolution of software systems
instead of aspect oriented programming. Presented abstraction in the form of patterns comes out from
integrating imperative, purely functional and object paradigms in the process functional paradigm and
it may contribute to the application of aspect oriented approach to the area of automatic evolution of
software systems.
