What Fig. 3 illustrated data object according to the present invention and state control logical separation system realizes schematic diagram.
As it is shown on figure 3, more thoroughly separate for realizing data object and state control logic, the present invention proposes a kind of separation method realized by data binding, state processing and data process, wherein,
Data binding realizes the data object mapping to status data, makes the data object can be independent from state logic, and keeps the synchronization of state between status data and data object；
Data have processed the activity of data object to be affected the change of data object, carries out verification and the conversion process of state simultaneously, and data process mainly following three kinds of implementations:
1, event processing mechanism, release the dependence between the active process of data object and state control logic code, the event that state control logic is sent by the activity of interception data object, trigger state control logic and process；
2, Plugin Mechanism, it it is the method for dependence between the another kind of active process releasing data object and state control logic code, state control logic is according to the movable specific plug-in specification of data object, state control logic is processed the movable plug-in unit list entering data object as a plug-in registration, the plug-in unit of registration is read in data object activity, thus completing the state control logic of data object；
3, method call, it is that the state control logic method that the active process of data object provides by calling state supervisor completes the state control logic of data object, under this mechanism, data object active process only depends on the signature of the state control logic method that state supervisor provides, do not rely on its internal logic, functionally data activity and state logic are separated and come.
It should be understood that, above-mentioned three kinds of implementations can combine between two or three kinds of combinations are applied, when event processing mechanism can not complete data process, Plugin Mechanism or method call is adopted to carry out data process, or when Plugin Mechanism can not complete data process, adopt method call or event processing mechanism to complete data and process.
The each several part shown in Fig. 3 is described in detail below in conjunction with other accompanying drawings.
1. data binding
Data binding simplifies application development.Data binding technology is to realize data object and movable and state logic separation method basis.Data object and status data object are through bound path direct correlation, and notice of change mechanism is responsible for the state that notification data object is up-to-date when state occurs to change, and synchronization of data objects records up-to-date state.So, it is to avoid by inactive logic resume module state logic the operation being converted to data object data.Meanwhile, binding mechanism dynamically changes BindingContext, and same state can process different data objects without the change making code.
Such as, in project management module, the state of project has different state numbers according to different item types.As shown in the table, define item types and status data:
State classification
| State classification | Item types |
| Proprietor | Proprietor's capital construction |
| General | General data |
| Proprietor | Proprietor's property |
State defines
| State | State classification |
| Newly-built | Proprietor |
| Issue | |
| Check and accept | |
| Completion | |
| Transfer | |
| Close | |
| Newly-built | General data |
| Issue | |
| Complete | |
| Close |
Project
| Item number | Item types | State |
| Proj01 | Proprietor's capital construction | Newly-built |
Pass through binding mechanism, when grassroot project Proj01 specifies item types for after " proprietor's capital construction " performing " preservation " operation, project Proj01 is tied to the state definition data of correspondence by the preservation activity of native system automatically, by triggering state control logic automatically by the status set " newly-built " of Proj01 object；When user performs after " issue " activity, binding mechanism automatically updates the state of Proj01 object to " issue "；Within the system, the program code of item objects does not need be concerned about the content how obtaining state and arrange in the status attribute of item objects.
Realizing in method at this, data bind the mutual approach providing data syn-chronization between data object and status data object.Specifying binding source and binding path in data object metadata, after metadata is loaded and is created as data object, control can automatically obtain the data of binding according to BindingContext, and synchronized update binds source when change.
2. state processing
In management software, business datum generally has different states, and when different, the performed business operation of data object has difference.When arranging certain activity and making service data object state change, the status attribute of data object can change.Such as project is likely to be at the states such as newly-built, issue, completion, closedown.Under different conditions, project allows to perform different movable control logic, such as whether can change, whether can cancel issues, the situation such as whether can close, this requires also to reflect project status while of project data, determine which to perform movable, it is not possible to it is movable which performs.
In generally exploitation, state control logic needs business logic modules to realize at active internal coding according to business datum state, it is necessary to more condition adjudgement operation, and logical code needs specific reference solidification to realize the control logic of state.This control mode is loaded down with trivial details and the degree of coupling is higher.State processing technology described herein can control to provide simple scheme for data object state.
State processing mechanism referent includes state supervisor, stateful example, state control item, State Transferring control item, the status object hierarchical structure in the state supervisor 204 that order is example, as shown in Figure 4.
1) set of state supervisor controlled state, and to have a state in this set be current state, keeps Tong Bu with the current state of data object；State set allows to arrange in design state, supports to extend according to actual needs at run mode, amendment or newly-built simultaneously.
2) method that state supervisor provides switching state, in order to program can be switched to another state from a state, and binds, by data, the state that notification data object is new；The method receives data object and activity, first read the current state of data object, then read the State Transferring control item set of this state, it is determined that whether current active triggers State Transferring, if triggered, then perform to be switched to the state of data object the process of dbjective state.
3) method that state supervisor provides status check, in order to program can verify whether current active under current state allows to perform；The method receives data object and activity, first reads the current state of data object, then reads the state control item set of this state, it is determined that whether current active allows perform and return result.
4) in each state, definable comprises the set of multiple state control item, judges whether the activity of each control item self or the activity of other data allow to perform in this condition based on this state control item；This set allows to arrange in design state, supports to extend according to actual needs at run mode, amendment or newly-built simultaneously.
5) in each state, definable comprises the set of multiple State Transferring control item, and in this condition, after this activity performs, the state of data object is switched to that state in the activity of each State Transferring control data object self；This set allows to arrange in design state, supports to extend according to actual needs at run mode, amendment or newly-built simultaneously.
6) state set of state supervisor, state control item set and State Transferring control item set support operationally dynamic expansion and amendment or newly-built according to actual needs, to support that actual flow process is for the flexible configuration of state.
3. data process
On the basis realizing state supervisor, data process by event handling or Plugin Mechanism or service call, and data object and state supervisor are set up logic association.When execution activity, automatically the current state value of data object is obtained, before performing, whether notice state supervisor verification activity can perform, after activity has performed, notice state supervisor switches current state, after state supervisor switching current state, binding mechanism notification data Obj State is changed, and automatically delivers last state value to data object, the then status attribute of refresh data object.
Data process mainly following three kinds of modes:
1, event processing mechanism (with reference to Fig. 5), release the dependence between the active process of data object and state control logic code, the event that state control logic is sent by the activity of interception data object, trigger state control logic and process；
The processing procedure of event processing mechanism is as follows:
1) when performing certain activity for data object, the example of this activity acquisition data object, and it can be used as the parameter of event, send the beginning event of this activity；
2) state supervisor intercepts the beginning event of this activity, calls status check method, back-checking result；
3) if verification is not passed through, state supervisor returns the abnormal results not passed through；
4) this abnormal results of this active reception, and by this abnormal results's return activity caller；
5), after activity has performed, what send this activity completes event；
6) what state supervisor intercepted this activity completes event, calls state transition method, performs State Transferring.
2, Plugin Mechanism (with reference to Fig. 6), it it is the method for dependence between the another kind of active process releasing data object and state control logic code, state control logic is according to the movable specific plug-in specification of data object, state control logic is processed the movable plug-in unit list entering data object as a plug-in registration, the plug-in unit of registration is read in data object activity, thus completing the state control logic of data object；
The processing procedure of board processing machine is as follows:
1) design state, before the process that state supervisor is announced for activity with complete plug-in unit standard, write satisfactory status check and State Transferring plug-in code, inside this plug-in code, call status check method and the state transition method of state supervisor respectively；
2) when performing certain activity for data object, this activity obtains the example of data object, calls and processes the plug-in unit of registration in anterior plug-in, calls the verification plug-in unit of state supervisor；
3) the verification plug-in unit of state supervisor calls status check method, back-checking result；
4) if verification is not passed through, state supervisor returns the abnormal results not passed through；
5) abnormal results that this active reception does not pass through, return activity caller；
6) after activity has performed, having called the plug-in unit of registration in plug-in unit, that calls state supervisor completes plug-in unit；
7) the verification plug-in unit of state supervisor calls state transition method, performs State Transferring.
3, method call (with reference to Fig. 7), it it is the active process of data object, the state control logic method provided by calling state supervisor completes the state control logic of data object, under this mechanism, data object active process only depends on the signature of the state control logic method that state supervisor provides, do not rely on its internal logic, functionally data activity and state logic are separated and come.
The treatment mechanism process of method call is as follows:
1) design state, the movable status check method according to state supervisor announcement and state transition method, the code writing status check method and the state transition method calling state supervisor at active internal respectively realizes；
2), when running, when performing certain activity for data object, this activity obtains the example of data object, actively calls the method for calibration of state supervisor；
2) if verification is not passed through, state supervisor returns the abnormal results not passed through；
3) abnormal results that this active reception does not pass through, return activity caller.
4) verification is passed through, execution activity.
5) when activity has performed, call the state transition method of state supervisor, perform State Transferring.
Use data binding, state processing, data processing technique when design according to technical scheme and the time of operation has all split the dependence coupled relation between data object and state control logic, support to extend according to actual needs in design state and run mode, amendment or newly-built state and control logic, logical code without amendment data object and activity thereof, it is achieved that data object and the movable purpose being separated with control logic.
