Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Encapsulation is that the method encapsulation of data and these data of processing is as a whole, is embodied in the abstract of class, is OO key property.OMCI agreement has been abstracted into all management amounts the form of OMCI entity, and each entity becomes OMCI mib information as a managed amount, therefore by each OMCI entity abstract be a class; According to the points relationship of inter-entity, a plurality of entity class are associated, finally realize the establishment of OMCI business model.
A kind of implementation method of the OMCI entity based on Object-oriented Technique, comprise: with OO method encapsulation OMCI entity, described OMCI entity comprises entity attribute, physical operation and inter-entity relation, and described entity attribute is as the attribute of class, and entity attribute is as data member; Described physical operation is as the method for class, and physical operation is as member function.Concrete, by OMCI entity division, be base class and the deriving custom entities class of inheriting base class, common feature to OMCI entity is concluded, construct a base class, as the basic framework of other OMCI entity class of structure, the public attribute that has comprised entity in this base class, with the form of Virtual Function, realize the operation that all entities of defining in standard may be supported.Example is the Different Individual of same entity, therefore adopts the instantiation of class to carry out abstract.Described deriving custom entities class may have multiple sorting technique, and in the present embodiment, described deriving custom entities class is divided into alarm entity base class, performance collection entity base class and common entity class.Described alarm entity base class be by the basic operation of alarm abstract be a class, this alarm entity base class is inherited from base class, as the parent of all alarm entities; Described performance collection entity base class be by the basic operation of performance collection abstract be a class, this performance collection entity base class is inherited from base class, gathers the parent of entity as all properties; Described common entity class is directly inherited from base class.
Described base class and deriving custom entities class are encapsulated by OO method respectively, the OMCI entity having encapsulated, by the succession of class, realize the expansion of OMCI entity, the succession of class comprises that subclass succession is from parent, but subclass, except inheriting from the method for parent, allows according to demand the method in parent to be rewritten.And, utilize OMCI inter-entity relation, realize a plurality of OMCI entities interconnected.OMCI inter-entity relation comprises explicit points relationship and implicit pointing relation.Described demonstration points relationship is presented as: a pointer that attribute is directed entity of class, by pointer, entity is carried out to association, and first directed entity will create; Described implicit pointing relation is presented as: the entity class being associated has identical instance number property value, each entity class will be safeguarded an associated instance table, store the entity associated with it, when creating entity, need to check whether have associated entity, if exist, added associated instance table.
In said process, by each OMCI entity abstract be " class ", as shown in table 1, be the corresponding relation of the composition of OMCI entity and the ingredient of class: the attribute of entity is abstract is the data member of class; Moving and notify abstract is the member function of class.For example at ITU-TG.988 protocol definition entity MAC bridge port configuration data, this entity comprises: 14 attributes such as Managed entity id, Bridge id pointer, and these 14 attributes are abstract is the data member of its corresponding entity class; Such supports 4 basic operation Create, delete, and get, set, these 4 operate accordingly abstract is 4 member functions of entity class; And this entity is supported the alarm operations such as Port blocking, in its entity class, need to define alarm Port blocking detection, report etc. and to process function.And the relation of itself and other entity is presented as two kinds, a kind of is that implicit expression is associated, by identical Managed entity id property value and other entity associated; Another kind is explicit association, and for example its Bridge id pointer attribute has been determined the MAC bridge service profile entity of its sensing.
Table 1
As shown in Figure 1, be the inheritance of OMCI entity class.Because OMCI entity has similar structure, each OMCI entity is comprised of entity attribute, instance method and several parts of inter-entity relation, and then the method that must have part in the member function of different entities class has similar operation, therefore be directly class of each OMCI entity structure, can produce a large amount of redundant codes.And OO inheritance has well increased the reusability of code, it is by the derivation function embodiment of class, and subclass can directly be inherited whole descriptions of its parent, and can modify and expand.Based on above description, design a kind of inheritance hierarchy structure of entity class, comprise the following steps:
Step S101: create base class.Base class 101 is parents of all OMCI entity class, and it is the abstract of all entity conventional methods, and some total attributes that are about to OMCI entity are summarized in this type of data member as such as: ME ID; The basic operation of stipulating in OMCI agreement, if: the operation such as create, delete, set, get is as such member function, is realized to these methods with the form of Virtual Function; And the common method of operating that each entity inside may be used is summarized in this type of.
Step S102: based on base class 101 deriving custom entities classes.Different according to the function of OMCI entity, OMCI entity is divided into 3 classes and processes: common entity, containing the entity of alarm operation, and performance statistics related entities.Common entity: common entity class 122 is directly inherited from base class 101, it can also, according to the functional characteristic of self, define distinctive attribute and method except can inheriting the attribute and method of base class 101.Entity containing alarm operation: compare common entity, the entity that contains alarm operation need to carry out the sequence of operations that alarm is relevant.Therefore, definition alarm entity base class 111 is as the common parent of alarm operation entity, and such is directly inherited from base class 101, all methods of shared base class 101, and define the co-operate of alarm entity: the generation of alarm, report, the basic operation such as elimination.Alarm entity class 121 is the abstract of an entity with alarm operation, and it is the subclass of alarm entity base class 111, and on this basis, increases the particular attribute of this entity and the definition of method.Performance statistics related entities: with containing the entity class of alarm operation seemingly, the entity that performance statistics is relevant need to carry out the sequence of operations such as performance collection, statistics.Therefore similar, performance statistics entity base class 112 is as the parent of the entity containing performance statistics function, increased the relevant basic operation of performance collection, statistics on the basis of base class 101; Performance statistics entity class 123 is entity abstract with performance statistics function, and it is the subclass of performance statistics entity base class 112, and the own distinctive method of definition and characteristic.In above-mentioned process, subclass, except inheriting from the method for parent, allows according to demand the method in parent to be rewritten, and when sending a universal information, can, according to the object difference of receipt message, implement different disposal routes like this.
OMCI service needed realizes jointly by a plurality of entities, and inter-entity relation is also an important composition of OMCI entity description, by the relation of inter-entity, entity is carried out to association and has formed business model.Relation between entity can be divided into two large classes: show points relationship and implicit pointing relation.
As shown in Figure 2, show points relationship: show that points relationship is represented by arrow, the explicit sensing entity B of entity A.Show that points relationship is presented as pointer that points to entity B of entity A storage in code.Therefore, should first create the example of entity B, and then the example of establishment entity A, and the pointer that the attribute that entity A is set is entity B, according to OMCI agreement regulation, entity is deleted and the reversed in order creating, in the present embodiment, when the example of delete entity A, should first check the example of whether deleting the entity B associated with it.Implicit pointing relation: entity C and entity D are recessive associated by instance number, when created the example of entity C, needs to check the example that whether has an entity D number identical with the example, as existence adds this example in its associated instance list.
Only otherwise violate above-mentioned entity relationship rule, so mode is not unique to the process that issues of OMCI business model, as long as the model issuing is complete, thinks that it is exactly correct configuring.
The present invention is not limited to above-mentioned embodiment, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, within these improvements and modifications are also considered as protection scope of the present invention.The content not being described in detail in this instructions belongs to the known prior art of professional and technical personnel in the field.
