There is attribute message summary to be referred to as eap-message digest 1；All properties eap-message digest of this object in addition to object oriented is referred to as message
Summary 2；All direct lower floor's object message summaries of this object are referred to as eap-message digest 3；
(5) i=1；The level currently compared in i representational level structural libraries；
Layer_num=max (depth of first buffering area hierarchical structure, the depth of second buffering area hierarchical structure)；
(6) respectively by the four-tuples of all objects of the i-th level in the first and second buffering area hierarchical structure storehouses (eap-message digest 1,
Object oriented, eap-message digest 2, eap-message digest 3) array is ranked up according to eap-message digest 1, and by first and second after sequence
The four-tuple of the corresponding object of the i-th level is compared in buffering area hierarchical structure storehouse, is sentenced according to the comparative result situation of appearance
Whether disconnected object oriented changes, whether object properties change, whether the subobject of object changes；And respective settings
" whether subobject needs further comparison " mark, and the object is inserted《Object updates registration form》、《The newly-increased registration of object
Table》Or《Object deletes registration form》；
(7) i=i+1；
(8) i is judged>layer_numIn this way, turn (10)；Such as no, turn (9)；
(9) respectively by its " whether subobject needs to compare " mark of the i-th level in the first and second buffering area hierarchical structure storehouses
Being set as the four-tuples of all direct subobjects of all objects of "Yes", (eap-message digest 1, object oriented, eap-message digest 2, disappear
3) array is ranked up breath summary according to eap-message digest 1, and the two four-tuple arrays are compared, and is turned (7)；
(10) terminate.
