In embodiments of the present invention, read and the call flow node on micro-order detailed process as shown in Figure 2:
In step S201, judge the current execution object that whether exists.Be execution in step S202 then, otherwise finish.
In embodiments of the present invention, described execution object is for carrying out the object of flow scheduling function, it is always corresponding with a flow nodes that each carries out object, be used for following the tracks of the once execution life cycle (from multiple entry branch convergence processing, calling service, startup descendant node, relevant treatment etc. before finish) of this flow nodes, record is carried out relevant runtime information, the address that wherein the most important thing is to obtain current pending micro-order with node.If currently have a pending object, then obtain the microprogram of described execution object, if there is no pending object then finishes.
In step S202, obtain the microprogram of described execution object.
In embodiments of the present invention, microprogram refers to the sequence that is made of micro-order, and the function relevant with flow scheduling is to represent by the microprogram that micro-order forms on each flow nodes.
In step S203, judge whether described microprogram finishes, be then to carry out S201, otherwise carry out S204.
In embodiments of the present invention, after obtaining the microprogram of described execution object, described microprogram is judged, if described microprogram finishes, then return step S201, rejudge whether there are other pending objects, if described microprogram does not finish, then obtain the micro-order in the described microprogram.

In embodiments of the present invention, when flow performing when unusual, execution is to carry out by the order of micro-order in the microprogram, the acquiescence rreturn value that is the current microinstruction manner of execution is " next instruction ", and is unusual if flow process occurs, and can carry out according to the execution route that pre-sets, rreturn value may be the call number of " specific instruction ", current execution object is addressed to corresponding micro-order according to rreturn value and carries out, and returns step S202 after executing, until current microprogram executes.Wherein, the execution of part micro-order can cause other flow nodes to be activated, thereby trigger the execution of other flow nodes, push process is transferred to another flow nodes from a flow nodes, until whole flow process finishes (or because wait for that outside result suspends or unsuccessfully wait because of execute exception).
As another embodiment of the present invention, as shown in Figure 3, in step S305, judge whether the rreturn value of the manner of execution of current microinstruction is " shutdown ".If it is execution in step S301 rejudges whether there are other pending objects.If otherwise execution in step S306 is addressed to micro-order corresponding in the described microprogram according to rreturn value.
Embodiment two:
Fig. 4 shows the structural drawing of the control device of the generalized flowsheet scheduling engine that the embodiment of the invention provides, and for convenience of explanation, only shows the part relevant with the embodiment of the invention.
The control device of this generalized flowsheet scheduling engine can be used for various terminals, for example mobile phone, pocket computing machine (Pocket Personal Computer, PPC), palm PC, computing machine, notebook computer, personal digital assistant (Personal Digital Assistant, PDA) etc., can be to run on the unit that software unit, hardware cell or software and hardware in these terminals combine, also can be used as independently, suspension member is integrated in these terminals or runs in the application system of these terminals, wherein:
Operational order receiving element 41, being used for receiving the flow scheduling Function Classification is the operational order of characteristic.
In embodiments of the present invention, the flow scheduling function is subdivided into characteristic, each flow scheduling function can be divided into one or more characteristic.
Flow scheduling modeling unit 42 is used for setting up the corresponding relation of characteristic and micro-order, and described micro-order is stored on the flow nodes.
In embodiments of the present invention, take Fig. 5 as example, be used for describing the process modeling process based on characteristic: for simple flow control, whole flow process is considered as a large flow nodes, this flow nodes is called root node, with " $ " title as root node.Whole flow scheduling comprises establishment, forwarding function.Wherein, forwarding function is classified as again the characteristics such as order, mutual exclusion selection, parallel bifurcated, and sets up the corresponding relation of characteristic and micro-order, and the function that described micro-order is carried out stores on the flow nodes.Step is as follows:
The first step: create A, B, three flow nodes of C, then the microprogram example of whole flow process is as follows:
$:start-sub-nodes;waiting-for-children;end-flow;
A:notify-parent;end;
B:notify-parent;end;
C:notify-parent;end;
Its implication is:
Root node $ comprises three micro-orders, and the function of its execution is: the promoter flow nodes; Wait for that the sub-process node finishes; Process ends.
The execution function that flow nodes A/B/C comprises micro-order is: wake father's flow nodes up; Finish.
Second step: visioning procedure node A is to the transfer of flow nodes B, and shown in Fig. 5 a, then the microprogram example of whole flow process is as follows:
$:start-sub-nodes;waiting-for-children;end-flow;
A:sequence;end;
B:notify-parent;end;
C:notify-parent;end;
Compare with the first step, flow nodes A does not wake father's flow nodes (notify-parent) instruction up, because it has follow-up flow nodes, there is no need to wake up father's flow nodes before the end, wakes father's flow nodes up by its follow-up flow nodes B; But the instruction of flow nodes A becomes order (sequence) instruction, before expression flow nodes A finishes, directly start its follow-up flow nodes, owing to only have a follow-up flow nodes B, does not therefore need to carry out extra selection.
The 3rd step: visioning procedure node A is to the transfer of flow nodes C, and shown in Fig. 5 b, then the microprogram example of whole flow process is as follows:
$:start-sub-nodes;waiting-for-children;end-flow;
A:exclusive-choice;end;
B:notify-parent;end;
C:notify-parent;end;
Compare with second step, the sequence of flow nodes A (sequence) instruction has become mutual exclusion selection (exclusive-choice) instruction, this is because flow nodes A has had two follow-up flow nodes, according to the default treatment rule, get the follow-up flow nodes that first satisfies condition when a plurality of follow-up flow nodes is arranged, i.e. (exclusive-choice) selected in mutual exclusion.
The 4th step: enable parallel bifurcated characteristic on the flow nodes A, then the microprogram example of whole flow process is as follows:
$:start-sub-nodes;waiting-for-children;end-flow;
A:fork;end;
B:notify-parent;end;
C:notify-parent;end;
Compare with the 3rd step, the mutual exclusion of flow nodes A selects (exclusive-choice) instruction to become intersection (fork) instruction, needs to start its all follow-up flow nodes before expression flow nodes A finishes, that is: follow-up flow nodes B and follow-up flow nodes C.
Because above-mentioned node does not comprise any calling service, so in the microprogram of each node, the not instruction relevant with calling service.
Flow scheduling performance element 43 for the micro-order that reads and call on the described flow nodes, is carried out the flow scheduling function.Wherein, flow scheduling performance element 43 also comprises flow scheduling control module 431, for the micro-order that reads and call on the described flow nodes.The flow scheduling control module comprises again carries out object control module 4311, microprogram control module 4312 and micro-order addressed module 4313.
Carry out object control module 4311, be used for when there is pending object in flow operating period, obtaining the current microprogram of described execution object; When not having pending object, then finish to carry out.
Micro-order addressed module 4313 is used for being addressed to micro-order corresponding to described microprogram according to rreturn value.
In embodiments of the present invention, when flow performing when unusual, execution is to carry out by the order of micro-order in the microprogram, the acquiescence rreturn value that is the current microinstruction manner of execution is " next instruction ", if flow process occurs unusual, can carry out according to the execution route that pre-sets, rreturn value may be the call number of " specific instruction ", is addressed to corresponding micro-order according to rreturn value.
As another embodiment of the present invention, comprise also and shut down module 4314 that the rreturn value that is used for when the manner of execution of micro-order is " shutdown ", finishes the execution of current flow nodes, rejudges whether there are other pending objects in the flow process.
In embodiments of the present invention, or by Fig. 5 the implementation of flow scheduling is specifically described, the flow scheduling control module reads and calls micro-order, and the process of carrying out the flow scheduling function is as follows:
The flow scheduling control module is obtained the current microprogram of carrying out object, read and call first micro-order on the root node $-promoter flow nodes (start-sub-nodes), after executing, rreturn value is " next instruction ", whether order is carried out second micro-order of root node $-inspection sub-process node and is finished, so because do not finish to shut down (waiting-for-children), rreturn value is " shutdown ", the flow scheduling control module is no longer carried out root node, but from pending object stack, get access to the execution object of flow nodes A, article one micro-order of XM A-follow-up flow nodes B of startup and follow-up flow nodes C(fork characteristic), after executing, rreturn value is " next instruction ", order is carried out second micro-order of flow nodes A-finish current flow nodes (end), rreturn value is " shutdown ", the flow scheduling controller is XM A no longer, but from pending object stack, get access to the next object of carrying out, it is the execution object of node C, and carry out its article one micro-order-wake up father's flow nodes (notify-parent) of flow nodes A, executing rear root node $ joins in the pending object, rreturn value is " next instruction ", and order is carried out second micro-order of flow nodes C-finish current flow nodes (end); The next microprogram of carrying out object is obtained in continuation from pending object stack, be root node $, whether read and call micro-order on the root node $-inspection sub-process node finishes, so do not shut down (waiting-for-children) micro-order because finish to carry out, rreturn value is " shutdown ", the flow scheduling controller continues to obtain the next object of carrying out from pending object stack, it is Node B, and carry out its article one micro-order-wake up father's flow nodes (notify-parent) of flow nodes A, executing rear root node $ joins again in the pending object stack, rreturn value is " next instruction ", and order is carried out the micro-order of flow nodes B-finish current flow nodes (end); Whether the next object root node $ that carries out is obtained in continuation from pending object stack, read and call current micro-order-inspection sub-process node and finish, because the sub-process node all finishes, carries out process ends (end-flow) micro-order.
For the easier process of understanding the flow scheduling execution, above step has been ignored the part that the flow process mistake is processed.
One of ordinary skill in the art will appreciate that, realize that all or part of step in above-described embodiment method is to come the relevant hardware of instruction to finish by program, described program can be in being stored in a computer read/write memory medium, described storage medium is such as ROM/RAM, disk, CD etc.
