protected boolean[]	isReady The condition whether the bit is ready
protected MacroFlowGraph	mfg The current macro flow graph
protected int[][]	vector The conditions which set into the executable conditions when the macro task finishes executing
protected int	vectSize Ths size of the bit vector

Constructor Summary

DataAccessCondition(MdfEnvironment e, MacroFlowGraph g)
