Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Encapsulation is that data are encapsulated as into an entirety with the method for handling the data, is embodied in the abstract of class, is towards right
The key property of elephant.All management amounts have been abstracted into the form of OMCI entities by OMCI agreements, each entity as one by
Management amount turns into OMCI mib informations, therefore each OMCI entities are abstracted as into a class；, will according to the points relationship of inter-entity
Multiple entity class associations, finally realize the establishment of OMCI business models.
A kind of implementation method of the OMCI entities based on Object-oriented Technique, including：Encapsulated with Object--oriented method
OMCI entities, the OMCI entities include entity attribute, physical operation and inter-entity relation, category of the entity attribute as class
Property, i.e., entity attribute is as data member；Method of the physical operation as class, i.e., physical operation is as member function.Tool
Body, it is base class and the deriving custom entities class for inheriting base class by OMCI entity divisions, the common feature of OMCI entities is concluded,
Construct a base class, as the basic framework for constructing other OMCI entity class, contain in the base class entity public attribute, with
The form of Virtual Function realizes the operation that all entities defined in specification may be supported.Example is the difference of same entity
Body, therefore be abstracted using the instantiation of class.The deriving custom entities class may have a variety of sorting techniques, in the present embodiment, institute
State deriving custom entities class and be divided into alarm entity base class, performance collection entity base class and common solid class.It is described alarm entity base class be
The basic operation of alarm is abstracted as a class, the alarm entity base class is inherited from base class, the parent as all alarm entities；
The performance collection entity base class is that the basic operation of performance collection is abstracted as into a class, and performance collection entity base class is inherited
From base class, the parent as all properties collection entity；The common solid class is directly inherited from base class.
The base class and deriving custom entities class are encapsulated with Object--oriented method respectively, encapsulate the OMCI entities of completion, is led to
The extension of OMCI entities is realized in the succession for crossing class, and the succession of class is inherited from parent including subclass, but subclass is removed and is inherited from parent
Method outside, it is allowed to the method in parent is written over according to demand.Also, OMCI inter-entity relations are utilized, are realized multiple
OMCI entities interconnect.OMCI inter-entity relation includes explicit points relationship and implicit points relationship.The display points relationship body
It is now：One attribute of class is the pointer for being pointed at entity, is associated by referring to for entity, and the entity being pointed at will
Create first；The implicit points relationship is presented as：Associated entity class has identical instance number property value, each entity
Class will safeguard an associated instance table, store entity associated with it, when creating entity, it is necessary to check for association in fact
Body, if being added into associated instance table in the presence of if.
In said process, each OMCI entities are abstracted as " class ", are the composition and class of OMCI entities as shown in table 1
The corresponding relation of part：Entity attributes are abstracted as the data member of class；Action and notice are abstracted as the member function of class.
Such as entity MAC bridge port configuration data, the entity include in ITU-TG.988 protocol definitions：
14 attributes such as Managed entity id, Bridge id pointer, this 14 attribute abstractions are its corresponding entity class
Data member；Such supports 4 basic operations Create, delete, get, set, and this 4 operations are abstracted as entity class accordingly
4 member functions；And the entity supports the alarm operations such as Port blocking, then definition is needed to accuse in its entity class
Alert Port blocking detection, the processing function such as report.And the relation of itself and other entities is presented as two kinds, one kind is hidden
Formula associates, and passes through identical Managed entity id property values and other entity associateds；Another kind is explicit associations, such as
Its Bridge id pointer attribute then determines its MAC bridge service profile entity pointed to.
Table 1
As shown in Figure 1, it is the inheritance of OMCI entity class.Because OMCI entities have similar structure, each OMCI
Entity is all made up of entity attribute, instance method and several parts of inter-entity relation, and then in the member function of different entities class
Necessarily having the method for part has similar operation, therefore is directly each one class of OMCI entity structures, can produce a large amount of
Redundant code.And the inheritance of object-oriented adds the reusability of code well, it is by the derivation function embodiment of class, son
Class can directly inherit whole descriptions of its parent, and can modify and expand.Based on above description, design a kind of real
The inheritance hierarchy structure of body class, comprises the following steps：
Step S101：Create base class.Base class 101 is the parent of all OMCI entity class, and it is all entity conventional methods
It is abstract, i.e., by some shared attributes of OMCI entities such as：ME ID are summarized in such middle data member as such；Will
Basic operation specified in OMCI agreements is such as：The operations such as create, delete, set, get are as such member function, with void
The form of function realizes these methods；And the common operating method that may be used inside each entity be summarized in it is such in.
Step S102：Based on the deriving custom entities class of base class 101.It is different according to the function of OMCI entities, OMCI entities are divided into 3
Class is handled：Common solid, the entity containing alarm operation, and performance statistics related entities.Common solid：Common solid class
122 are directly inherited from base class 101, and it, can also be according to the function of itself in addition to the attribute and method that can inherit base class 101
Characteristic, define distinctive attribute and method.Entity containing alarm operation：Compared to common solid, the entity containing alarm operation needs
Carry out the related sequence of operations of alarm.Therefore, the definition alarm entity 111 common parent as alarm operation entity of base class,
Such is directly inherited from base class 101, shares all methods of base class 101, and defines the co-operation of alarm entity：Alarm
The basic operation such as produce, report, eliminating.Alarm entity class 121 is the abstract of entity with alarm operation, and it is alarm
The subclass of entity base class 111, and on this basis, increase the particular attribute of the entity and the definition of method.Performance statistics is related
Entity：Similar with the entity containing alarm operation, the related entity of performance statistics needs to carry out a series of behaviour such as performance collection, statistics
Make.Therefore similar, parent of the performance statistics entity base class 112 as the entity of the function containing performance statistics, in the base of base class 101
Performance collection, the related basic operation of statistics are added on plinth；Performance statistics entity class 123 is the reality for having performance statistics function
Body is abstracted, and it is the subclass of performance statistics entity base class 112, and defines oneself distinctive method and characteristic.Above-mentioned
During, subclass is in addition to the method for being inherited from parent, it is allowed to the method in parent is written over according to demand, so works as transmission
, can be different according to the object for receiving message during one universal information, implement different processing methods.
OMCI business needs to realize jointly by multiple entities, and inter-entity relation is also one of OMCI entity descriptions important
Entity, is associated and constitutes business model by composition by the relation of inter-entity.Relation between entity can be divided into two major classes：
Show points relationship and implicit points relationship.
As shown in Fig. 2 display points relationship：Display points relationship is indicated by means of an arrow, and entity A explicitly points to entity B.Display
Points relationship is presented as that entity A stores the pointer of a sensing entity B in code.Therefore, it should create the reality of entity B first
Example, then creates the example of entity A again, and sets the attribute of entity A to be provided for the pointer of entity B according to OMCI agreements, real
Body is deleted with the order created on the contrary, then in the present embodiment, when deleting the example of entity A, it should first check whether
Delete the example of entity B associated with it.Implicit points relationship：Entity C associates with entity D by the way that instance number is recessive, such as creates
, it is necessary to check for an example with the example identical entity D during entity C example, by this reality if existing
Example is added in its associated instance list.
As long as the process that issues of OMCI business models does not violate above-mentioned entity relationship rule, therefore mode is not unique
, as long as the model issued is complete, then it is assumed that configuration is exactly correct.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as the protection of the present invention
Within the scope of.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
