Parola: um framework para construção de aplicações J2SE baseadas em plug-ins

Abstract

Parola is a framework for image processing applications that works by constructing graphical user interfaces, controlling the mathematical methods and managing images. Systems built by the Parola approach receive new features by developing and installing plug-ins. Plug-ins are created with more structural independence than traditional software components, because they just need to know the border objects to communicate with the system. Thus, the plug-ins’ developers don’t need profound knowledge regarding the system’s architecture, but they do need to know the basic rules for communication between the software platform and the plug-in. This work demonstrates the use of some software engineering techniques and design patterns to construct a framework for managing plugins using the J2SE (Java 2 Platform, Standard Edition) technology.
