Research and application of multiple pattern fusion on decorative pattern

Design patterns played a key role in improving the efficiency and quality of software object-oriented development. Decorator in this paper, as one of them, was mainly improved in three points for some problems on algorithm alteration and system compatibility. One was that explored multiple patterns fusion´s solutions of decorator with strategy and adapter; another was that put forward two new anti-patterns for warning the user in view of some negative aspects for three new fused models. Finally, it verified its superiority through examples and illustrated some unsolved problems after model fusion.
