In PDM system can there is multiclass relation in CAD document object, parts and CAD document associations comprise " owner ", " content ", " provide content ", " image ", the relation such as " provide image ", between CAD document, also can be built into " use relation ", " referring-to relation ", " modification relation ", relations such as " source and image relations ", because existing system is just enumerated the simple increase of object relationship, already present object relationship is not carried out to abstract classification, cannot realize dynamic-configuration, cause existing relation management complexity to improve, relation cannot extendability, increase a kind of business object and will add a kind of type of relationship and related service logical operation.The present invention uses dynamic relationship configuration extended method to address the above problem, user configures expansion type relation, the feature operation of defining relation two ends, meet the basic management of the CAD document relationships in PDM system, also can dynamically increase relationship type according to Added Business object, to being related to that two ends operation also can realize different functions by configuration dynamic load.
Existing CAD object relationship management is solidificated in the impact property operation of existing relationship type and relation in system, be related to that for newly-increased relationship type and modification the operation of two ends object cannot dynamically realize, during like this in the face of different enterprises and user, need to carry out customized development work, again to existing business function and new finishing functions analysis, thereby cause the dirigibility extendability of PDM system very poor, and newly-increased modification also can bring stability problem to system at every turn.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, a kind of configuration of the expandable method based on CAD document relationships is provided, can realize in the situation that not restarting service and completing with regard to capable of dynamic, thereby increase CAD object relationship business function in PDM system, can adapt to various flexible and changeable business.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of configuration of the expandable method based on CAD document relationships, is characterized in that: step is as follows:
Step 1: determine relationship type according to the object at two ends;
Step 2: determine according to the impact property of the definite relationship type of step 1 this relationship type is to belong to which kind of operative relationship;
Step 3: which generic operation what determine the association of operative relationship two ends according to relationship type is.
As the improved technical scheme of one, described specific procedure realization flow:
Step 1: system is upgraded the configuration file of CAD document object relation automatically in Installed System Memory;
Step 2: system reads configuration file in the time creating CAD document relationships data, generates different object relationships according to the object type that is related to two ends in configuration file;
Step 3: CAD document object is operated, by configuration search operation relationship type, judge whether to call left end object according to the impact property of type;
Step 4: if left end object receives call, whether configure by searching acceptable operation, if this operation is carried out in configuration, if not configuration is returned;
Step 5: if the configuration operation relationship type reading in step 3 is revised, will judge whether to call left end object according to new type.
Owing to having adopted technique scheme, compared with prior art, the present invention, by using CAD document relationships exterior arrangement technology, can make PDM system realize the dynamic expansion of CAD document relationships, and the management of this CAD document object relation only need to be revised configuration file and just can complete.For example: enterprise's Added Business object, also to increase object relationship type newly simultaneously, so just can make PDM system adapt to fast new business by relationship type between configuration object.For different enterprises, some needs same relation configuration different operating, as owner's relation of parts and CAD document, general utility functions is that right-hand member CAD object detects modification, left end component object also needs to detect equally processing, do not carry out other operations if the same relationship type of certain enterprise needs right-hand member CAD document object to detect left end object, in relation configuration, delete the configuration interface operation of left end, just can realize the business function of requirement.Thisly be related to that expansion technique is just automatically updated in the situation that of the service of restarting systems not, realized CAD object relationship in dynamic expansion PDM system, thereby adapted to the changeable business of enterprise.
Embodiment
Embodiment:
A kind of configuration of the expandable method based on CAD document relationships, step is as follows:
Step 1: determine relationship type according to the object at two ends;
Step 2: determine according to the impact property of the definite relationship type of step 1 this relationship type is to belong to which kind of operative relationship;
Step 3: any generic operation of determining the association of operative relationship two ends according to relationship type.
In the present embodiment, described specific procedure realization flow:
Step 1: system is upgraded the configuration file of CAD document object relation automatically in Installed System Memory;
Step 2: system reads configuration file in the time creating CAD document relationships data, generates different object relationships according to the object type that is related to two ends in configuration file;
Step 3: CAD document object is operated, by configuration search operation relationship type, judge whether to call left end object according to the impact property of type;
Step 4: left end object receives and calls, by searching whether defined this operation of right-hand member in this operative relationship, if configuration is carried out this operation, otherwise returned;
Step 5: if the configuration operation relationship type reading in step 3 is revised, will judge whether to call left end object according to new type of relationship.
The present invention sums up contacting of conclusion relation impact property and relation and operation by the relationship type of existing CAD document, and by independent with configurable document form the coupling logic of business, CAD document object relation defines by configuration.
