Field Detail

listIdx

int[][] listIdx

A 2D array listIdx[3][len] is used. The entry listIdx[0][], listIdx[0][1] is used for each VirtualUniverse. The entry listIdx[2][0] is used for index to which one to use. This is used to handle the case the Node Object move from one VirtualUniverse A to another VirtualUniverse B. It is possible that another Structures in B may get the add message first before the Structures in A get the remove message to clear the entry. This cause MT problem. So a 2D array is used to resolve it.
