A MOP Based Constructive Reflective State Metamodel

Construction,management and extension of state space is crucial for many applications. Combining with frequent change of requirement of state space,these applications are rather complicated. Synthesizing techniques of refection architecture,MOP mechanism and metamodel,this paper advances a MOP(Meta Object Protocol) based constructive state metamodel,which defines construct and rules for building models with extensible structure for state space. Based on this metamodel,modeling with extension of state space that adopts decorator pattern and role object pattern is discussed. An implementation of modeling based on this metamodel is presented. With appropriate extension,models based on this metamodel can dynamically adapt state space change.
