Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description.

Embodiment one

The embodiment of the invention provides a kind of timer realization method, Fig. 3 is a kind of timing that the embodiment of the present invention proposes The flow chart one of device implementation method, as shown in figure 3, in an embodiment of the present invention, timer realization method may include following Step:

S101, according to preset orthogonal list structure, obtain the attribute value of timer Node；Wherein preset orthogonal list The data store organisation of structural characterization timer Node.

In an embodiment of the present invention, scheduler constructs timer Node, the reality of timer according to the request of automatic machine Existing device, that is, scheduler.Scheduler can obtain timer according to preset orthogonal list structure after constructing timer Node The attribute value of node, wherein the data store organisation of preset orthogonal list structural characterization timer Node.

It should be noted that automatic machine is commonly known as finite state machine in field of software development, with the side of automatic machine Formula handles problem and (only transmits money through explicit state between the step of formula of execution is divided into automatic machine and each step News) it is necessary some in the design of event-driven formula.

Illustratively, in network communication field, automatic machine can be understood as different communication protocol, and network session event Execution, completed based on communication protocol.

In an embodiment of the present invention, scheduler can receive the request of automatic machine and construct timer Node.Including certainly Motivation requests next event after having handled an event, and manages for one timer of next event request.Accordingly Ground, scheduler can receive the request of automatic machine and construct corresponding timer Node.Automatic machine request scheduling device creates timer The case where node further includes that current event is untreated, needs to create corresponding time out event, at this point, scheduler can also receive automatically The request of machine and construct corresponding timer Node.

Illustratively, automatic machine can then generate connection message after the message related to calls for completing a caller, at this point, adjusting It is the request that connection message creates timer that degree device, which can receive automatic machine,.Either automatic machine after issuing message related to calls, Caller does not receive feedback in predetermined time, and automatic machine may need to create corresponding time out event at this time, to prompt caller to exhale Message is made not to be successfully executed, it is the request that time out event creates timer that scheduler, which can also receive automatic machine, at this time.

It should be noted that in an embodiment of the present invention, scheduler is after constructing timer Node, according to preset Orthogonal list structure obtains the attribute of timer Node.It is wrapped in the data store organisation that preset orthogonal list structure is characterized Include automatic machine No. the first, to overtime number of days and time point.Scheduler obtains timer Node according to preset orthogonal list structure Attribute value be include the automatic machine No. the first for obtaining timer Node, first to overtime number of days and first time point.

Further, in an embodiment of the present invention, in the data store organisation that preset orthogonal list structure is characterized It further include the automatic machine number of each automatic machine in automatic machine queue, it is in an embodiment of the present invention, each automatic machine is corresponding Automatic machine be known as automatic machine No. the second.The attribute value of timer Node further includes automatic machine No. the second, so as to subsequent basis Automatic machine No. first automatic machine No. the second of corresponding taking-up.

Moreover, in an embodiment of the present invention, in the data store organisation that preset orthogonal list structure is characterized It further include four bidirectional pointers.Four bidirectional pointers safeguard orthogonal list when mainly timer being facilitated to delete.

Illustratively, when the timing that scheduler needs one to be had on orthogonal list up and down direction adjacent timing When device knot removal, following modification mode can be taken: the bottom pointer of the adjacent timer Node in modification top be currently to Delete the identical timer Node in lower section that timer Node bottom is directed toward；The top pointer of the adjacent timer Node in modification lower section The adjacent timer Node in top being directed toward for current timer Node top to be deleted；Modify the adjacent timer Node in the left side Right pointer is the adjacent timer Node in the right that current timer Node right to be deleted is directed toward；The adjacent timing in modification the right The left pointer of device node is the adjacent timer Node in the left side that current timer Node left to be deleted is directed toward.

In this way, the doubly linked list structure of horizontal remains unchanged, subsequently through water after deleting timer Node The doubly linked list gauge outfit of flat/vertical direction, still can normally traverse entire chained list.And by modifying timer section to be deleted The timer Node that point four direction pointer is directed toward is the next node of timer Node to be deleted, Algorithms T-cbmplexity It is very low, only o (1).

Further, in an embodiment of the present invention, the method that scheduler obtains automatic machine No. the first of timer Node Are as follows: the corresponding automatic machine number of automatic machine and first threshold modulus are obtained timer Node and correspond to preset cross chain by scheduler Automatic machine No. first of the row field of table structure；Wherein, the longitudinal length of first threshold characterization orthogonal list structure.

It should be noted that in an embodiment of the present invention, first threshold is a parameter, hash in orthogonal list structure Function (i.e. modulo operation) is automatic machine number (automatic machine No. the second) mod first threshold, for different automatic machines number, hash Functional value may be identical, and it is corresponding to be all placed on hash functional value for the corresponding timer Node of the identical automatic machine of each hash functional value In the conflict chained list that the corresponding conflict chained list gauge outfit of the orthogonal list longitudinal axis is directed toward, corresponding is automatic machine No. the first.In addition, such as Described in preceding, first threshold is a parameter, and the parameter value is adjustable, but in an embodiment of the present invention, and first Threshold value is preferably 2 power side, and such hash function can be obtained by displacement mode operation.It is understood that the first threshold Value is bigger, and conflict chained list is shorter, and search efficiency is higher, certainly bigger for the memory of memory contention chained list gauge outfit.

Illustratively, first threshold can be 8192, automatic for different automatic machine number (automatic machine No. the second), second Machine mod 8192 may identical (when such as the second automatic machine number=8293 and automatic machine No. the second=1, be by 8192 modulus 1).Automatic machine No. second be 8293 and second automatic machine number be 1 the corresponding timer Node of automatic machine be all placed on orthogonal list In the same conflict chained list that the corresponding conflict chained list gauge outfit of the longitudinal axis is directed toward.

Further, in an embodiment of the present invention, scheduler obtains the first side to overtime number of days of timer Node Method are as follows: timing length and second threshold are rounded by timer, obtain timer Node in data store organisation first to super When number of days；Wherein, timing length is the time to be triggered that automatic machine handles event, and second threshold characterizes the cross of orthogonal list structure To length.The method that scheduler obtains the first time point of timer Node are as follows: scheduler asks timing length and current time With rear and second threshold modulus, obtains timer Node and correspond to the first time point in the column field of orthogonal list structure；Wherein Current time refers to the offset of opposite morning zero point.

It should be noted that in an embodiment of the present invention, it is not absolute time that timing length, which is a relative time,.

Illustratively, second threshold 86400 represent one day duration, when scheduler is arranged according to the request of automatic machine One timing length is the timer Node of 49 hours 10 minutes durations, and timer Node days initial value is 2, the i.e. timer The first of node is 2 to overtime number of days.And at the time of in the horizontal axis characterization of orthogonal list one day, it can be understood as every on horizontal axis One lattice scale, which represents, shares 86400 lattice for 1 second one.When current time curSecond is 0 with respect to the offset of morning zero point, The corresponding current time curSecond of timing length is that curSecond pointer deviates 1 backward again in the horizontal axis coordinate of orthogonal list 10 minutes hours, i.e. curSecond pointer will deviate 4200 lattice backward；And when current time curSecond is with respect to morning zero point Offset when being 84000, the corresponding current time curSecond of timing length needs deviate 4200 lattice backward again, practical horizontal seat Target value be just 1800 (84000+4200 divided by 86400 after remainder).

In addition, it should be noted that, scheduler is during scanning timer Node, the every multiple scanning of scheduler to one The value of secondary current time, the first overtime day digital section in the data store organisation of timer Node just subtracts 1, when scheduler is found When the overtime number of days of the first of some timer Node is 0, indicates that time is up for the timer Node, need to trigger overtime thing Part.

S102, according to preset orthogonal list structure, the timer Node that attribute value characterizes is inserted into and preset ten The corresponding position of value of the row field and column field of word list structure generates timer；Wherein, preset orthogonal list structure Row field characterizes automatic machine No. the first, and the column field of preset orthogonal list structure characterizes time point.

In an embodiment of the present invention, scheduler, can be according to preset cross after the attribute value for obtaining timer Node The timer Node that attribute value characterizes is inserted into corresponding with the value of the row field of orthogonal list structure and column field by list structure Position, i.e., generation timer.

It include: first automatic as described in step S101, in the data store organisation of the timer Node in timer Machine number, first are to overtime number of days, first time point and automatic machine No. the second.

Illustratively, Fig. 4 is a kind of illustratively preset cross link structure of timer provided in an embodiment of the present invention Figure, as shown in figure 4, the horizontal axis of timer is 86400, unit is the second；The longitudinal axis is 8192, corresponding automatic machine No. first.The timing There are 5 timer Nodes in device, wherein timer Node 1 and the timing length having the same of timer Node 2, first are automatically Machine number and automatic machine No. the second；And timer Node 3 and the automatic machine No. first having the same of timer Node 1, but it is different Automatic machine No. second and first is to overtime number of days and first time point；Timer Node 4 and timer Node 1 are having the same Automatic machine No. first and automatic machine No. the second, but different first is to overtime number of days and first time point；Timer Node 5 and fixed When device node 1 have identical first time point, but different the first overtime number of days, the first autonumber and automatic machines No. the second.

It is understood that in an embodiment of the present invention, scheduler creation has the timing of orthogonal list storage organization Device, so that scheduler searches timer Node, and the time complexity for the operations such as deleting to timer Node reduces, convenient Management of the scheduler to timer.

Illustratively, Fig. 5 is a kind of flow diagram for timer realization method that the embodiment of the present invention proposes, such as Fig. 5 It is shown, this method comprises:

S201, scheduler construct timer Node according to the request of automatic machine.

FsmHash=fsmNo%8192 is arranged in S202, scheduler, and timeHash=is arranged (when curSecond+ timing It is long) %86400, timing length/86400 days=are set.

It should be noted that fsmHash is longitudinal first of orthogonal list in illustratively embodiment of the invention Automatic machine number, fsmNo are the automatic machine number (automatic machine No. the second) of automatic machine, and days is first to overtime number of days, and 8192 be the One threshold value, 86400 be second threshold.

The timer Node of construction is inserted into the corresponding Hash chained list gauge outfit of timeHash by S203, scheduler.

It should be noted that timeHash corresponds to the water of orthogonal list structure in illustratively embodiment of the invention Square to.

The timer Node of construction is inserted into the corresponding Hash chained list gauge outfit of fsmHash by S204, scheduler.

It should be noted that fsmHash corresponds to the vertical of orthogonal list structure in illustratively embodiment of the invention Direction.

By the process of the timer realization method of Fig. 5 it is found that scheduler is under the request of automatic machine, according to timing length With automatic machine number, calculate separately horizontally and vertically coordinate, then by timer Node be inserted into it is corresponding horizontal and Vertical direction chained list, Algorithms T-cbmplexity are o (1).

Embodiment two

Same inventive concept based on embodiment one, Fig. 6 are a kind of timer realization method that the embodiment of the present invention proposes Flowchart 2, as shown in fig. 6, in an embodiment of the present invention, after generating timer, i.e. after step S102, the present invention Embodiment provide a kind of timer realization method can with the following steps are included:

S103A, first time interval of the current time apart from previous scan is calculated, current time refers to opposite morning zero point Offset.

In an embodiment of the present invention, scheduler, can be based on pre- after the internet message for receiving the return of select system If the corresponding timer Node of orthogonal list structural scan.Before the scan, before scheduler can calculate current time distance The first time interval of secondary scanning.Wherein, current time refers to the offset of opposite morning zero point.

Scheduler can be swept after the creation for realizing the timer with orthogonal list structure based on orthogonal list structure Corresponding timer Node is retouched, scheduler can be referred to as timer queue scanning algorithm to the scan method of timer Node. Scheduler calls (such as 20 milliseconds) timer queue scanning algorithm at regular intervals, and the time interval called every time can not Together, in event-based model, timing time delay can be called by select system and be realized, in this way if stopped in select system There is internet message arrival during dormancy, select system can return to scheduler immediately and execute, rather than latency period always, To improve system response time and handling capacity.

Further, in an embodiment of the present invention, when current time is apart from the first time interval of previous scan time When no more than 0, illustrate that scheduler is terminated also without scanning timer, scanning process at this time.

S104A, in first time interval, obtain timer at least one first timer corresponding with current time Node.

In an embodiment of the present invention, when first time interval is greater than 0, scheduler obtains in first time interval At least one first timer node corresponding with current time in timer.

It should be noted that in an embodiment of the present invention, scheduler in first time interval, obtain in timer with At least one corresponding first timer node of current time refers to: obtaining each current time within the scope of first time interval On first timer node, wherein each current time is likely present multiple first timer nodes in vertical direction.

Illustratively, it is assumed that first timer node, second timer node and the 5th timer Node pair shown in Fig. 4 The first time point answered is 8631, then scheduler can obtain 3 timer Nodes under 8631 current time, wherein the The automatic machine No. the first and first timer node of five timer Nodes and the first automatic machine difference of second timer node.

Specifically, the method that scheduler obtains at least one first timer node are as follows: scheduler is in first time interval It is interior, update current time；When updated current time be less than second threshold when, obtain timer in it is updated current when Between at least one corresponding first timer node；Wherein, the lateral length of second threshold characterization orthogonal list structure.

It should be noted that in an embodiment of the present invention, current time is in corresponding orthogonal list structure on horizontal axis Time point, first time interval characterize scheduler and are based on the scannable range of current time.Scheduler is in first time interval model Interior traversal is enclosed, updated current time is based on, obtains at least one first timer node.

Illustratively, when second threshold is 86400, current time is the value between 0~86399, such as 8630.And first When time interval is 10 seconds, the scannable range of scheduler is 8631~8640.When any moment in the scanning range when Between o'clock less than 86400 when, scheduler just since 8631, obtains at least one corresponding timer section in timer by time point Point.Wherein, 8631~8640 any moment is updated current time.

Further, in an embodiment of the present invention, it includes: scheduler according to current time that scheduler, which updates current time, With the first prefixed time interval, obtained for the second time point；When being not less than second threshold at the second time point, current time is updated It is 0.

Illustratively, if current time be 86399, the first prefixed time interval be 1, then its second time point be When 86400, current time is reset to 0 at this time.In an embodiment of the present invention, the horizontal direction of orthogonal list can be interpreted as One annular, current time move in ring.

Further, in an embodiment of the present invention, scheduler update current time further include: scheduler according to it is current when Between and the second prefixed time interval, obtain the second time point；When being less than second threshold at the second time point, and work as in timer not When in the presence of at least one first timer node corresponding with the second time point, according between the second time point and the second preset time Every, obtain third time point, current time is updated to third time point.

Illustratively, when current time is 8630, the second prefixed time interval is 1, then the second time point was 8631, this Two time points, there is no the timer sections that first time point is 8631 less than 86400, and in the timer of orthogonal list structure When point, obtaining the third time at this time is 8632, and updating current time is 8632.

S105A, update the first of at least one first timer node to overtime number of days, first belong to overtime number of days it is fixed When device in timer Node attribute value.

In an embodiment of the present invention, it is fixed to will be updated at least one after obtaining at least one timer Node for scheduler When device node first to overtime number of days, wherein first is the attribute value of timer Node to overtime number of days.

It should be noted that in an embodiment of the present invention, the first of at least one first timer node is updated to super When number of days refer to when scheduler scans are at least one first timer node, by the of at least one timer Node One subtracts 1 to the value of overtime number of days.
