Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Fig. 1 shows a kind of flow diagram of the implementation method of threading operation according to an embodiment of the invention.Such as
Shown in Fig. 1, this method includes：
Step S110 obtains the mission bit stream of pending task.
Here, mission bit stream can be a plurality of types of, such as in one embodiment of the invention, in the above method,
Mission bit stream includes following one or more：Fundamental type object, lambda expression formula, pointer, intelligent pointer, common letter
Number.
It usually can realize using fundamental type object (such as integer object int, string char), pointer as ginseng
Number is transmitted, such as can transmit fundamental type by PostMessage in cross-thread.But Class Type (class class
Type, such as intelligent pointer) it tends not to be transmitted as the parameter of PostMessage.Therefore in the embodiment of the present invention
In, a kind of task template is realized, most types of parameter can be supported to transmit, and almost do not have to the number of parameters of transmitting
It is restricted.
Step S120 chooses the task template to match according to mission bit stream, and according to mission bit stream and times chosen
Business template generation task.
Step S130 executes task, or notice first object thread execution task in this thread.
As it can be seen that method shown in FIG. 1 can be chosen matching after the mission bit stream for getting pending task
Task template generates task, to be executed in this thread or other threads.The beneficial effect of the technical solution is,
Task template both supported it is extensive, it is more common, also support specialization, can be promoted in performance, and for a type
Task can use same task template, implement simple and convenient, efficiency is very high.
The process of notice first object thread execution task, which can be considered as, makes it execute an asynchronous task.I.e. in the present invention
One embodiment in, in the above method, pending task be asynchronous task, with the matched task template of mission bit stream be it is asynchronous
Task template.
Asynchronous task refers to that first object thread can execute task and this thread does not need to rely on its implementing result immediately
And waited, other tasks can be executed parallel.
In one embodiment of the invention, in the above method, asynchronous task template is from specified asynchronous task class
It obtains, asynchronous task Similar integral is from CWindowImpl class.
CWindowImpl class is the template class for being finally derived from CWindow class.It is different due to needing other threads to execute
Step task realizes that a window can be convenient the transmission of carry out task for the thread.In general, establishing window needs for a thread
CWindowImpl class is inherited, and in an embodiment of the present invention due to needing to realize asynchronous task with asynchronous task template, because
This asynchronous task class newly realized in the present embodiment can be inherit CWindowImpl class, be built such that window only need after
Hold the asynchronous task class newly realized.
In one embodiment of the invention, in the above method, mission bit stream includes that can call object and/or parameter, root
Generating task according to mission bit stream and the task template of selection includes：Mission bit stream is encapsulated as asynchronous task by asynchronous task template
Object.
Here, object can be called to can be function, lambda expression formula etc..Parameter can be calling, and this can call object
Parameter, type, quantity may each be diversified.
Wherein, the std that the specific implementation of asynchronous task object can be provided by c++ is encapsulated::Function is realized.
For example, fn (can call object), args (relevant parameter) are packaged into std::function<void()>.
But by debugging discovery, if directly using std::Function can generate unnecessary lvalue several times and copy
Shellfish and r value copy, therefore in one embodiment of the invention, in the above method, mission bit stream is sealed by asynchronous task template
Dress is that asynchronous task object includes：The encapsulation to asynchronous task object is realized using binding mechanism.
The binding mechanism is similar to the binding principle that Windows system provides, and is no longer discussed in detail herein.By binding machine
System substitution std::Function realizes encapsulation, it is possible to reduce unnecessary lvalue copy and r value copy above-mentioned.
In one embodiment of the invention, in the above method, notice first object thread execution task includes：It will be asynchronous
Task object is put into the message queue of first object thread, so that first object thread is receiving execution signal from message queue
Middle taking-up asynchronous task object executes asynchronous task.
As can be seen that this sample thread does not need to be concerned about how asynchronous task executes in subject thread, it is only necessary to will be different
Step task object assignment is put into message queue.This and PostMessage mode are not both fairly obvious, PostMessage
It is only one message of transmitting, the parameter of carrying is limited；And mode provided by the embodiment of the present invention, it is accomplished that task is transmitted,
The parameter type and quantity of carrying have all obtained great expansion.
Sometimes this thread needs first object thread to return to implementing result, such as main thread (UI thread) notice sub thread is held
Row time-consuming operation updates UI according to implementing result (User Interface, user interface are preceding same).Therefore in the present invention
One embodiment in, in the above method, mission bit stream include implementing result capture function；When implementing result capture function is by the
When one subject thread is called, implementing result is executed in the second subject thread and captures function, it is different to be captured from first object thread
The implementing result of step task.
Here the second subject thread is also possible to this thread.As can be seen that executing the process that implementing result captures function
It still can be an asynchronous procedure.Such to be advantageous in that, the first object thread for executing task can be indifferent to needs and return
Which data is returned, captures function by needing the second subject thread of these data to execute implementing result.
In one embodiment of the invention, in the above method, it is by expressing lambda that implementing result, which captures function,
What formula was packaged.
Also mentioning lambda expression formula above can be used as mission bit stream.Lambda expression formula be properly termed as anonymous function or
It is closure, may be implemented directly to execute at calling, does not need to state in advance.
In one embodiment of the invention, in the above method, implementing result capture function includes type extraction function, the
One capture function and the second capture function, the first capture function and the second capture function are overload function；Type extracts function and uses
In carrying out type extraction to implementing result, if the type prototype extracted does not include parameter, carried out using the first capture function
Capture is captured if the type prototype extracted includes parameter using the second capture function.
The mode that a kind of pair of performance further optimizes is provided in the present embodiment, that is, the class of c++11 offer has been provided
Type extracts thought, and the type prototype extracted for implementing result includes that parameter and two kinds of situations not comprising parameter carry out respectively
Specialization processing.Here type extraction function can be customized, and included function can also be applied.
In one embodiment of the invention, the above method further includes：Judge the first object thread for executing task
It whether there is, if it does not exist, then initialize the first object thread for executing task.
For example, be applicable in c++11 Programming, the template template provided using c++11, a kind of example realized is such as
Under：
template<typename Fn,typename...Args>
void ATPostTask(ATID atid,Fn&&fn,Args&&...args)；
Here Fn, which is still represented, can call object, and Args represents the parameter that can call object dependency.ATID is customized
Digital ID, it is corresponding with a thread, if corresponding ID is not present when executing the above method, illustrate that subject thread is not deposited
Needing to initialize a corresponding thread.
A specific example is given below, such as needs to execute Func (a, b) on thread ATID_DB, can have as follows
Several realizations：
1) ATPostTask (ATID_DB, Func, a, b), fn=Func, args=a, b；
2)ATPostTask(ATID_DB,[a,b]{Func(a,b)；), fn=[a, b] { Func (a, b)；, args=
It is empty；
3)ATPostTask(ATID_DB,[a](B b){Func(a,b)；, b), fn=[a] (B b) Func (a,
b)；, args=b；
As can be seen that parameter and the setting that can call object are extremely flexible in concrete implementation.
Above-described embodiment describes the transmitting of cross-thread parameter, realizes some modes of asynchronous task.And the side of threading operation
Only this is not a kind of for formula, is described below how task relevant to network request is realized.
In client-side program, if necessary to carry out network communication, network request is issued, that necessarily there are much applicable fields
Scape, usual developer can be realized with independent dynamic link library dll.Network request is generally accompanied with corresponding readjustment
Processing, is found by analysis, and there are the following problems for the poor dynamic link library of some exploitations：Each readjustment will define one
Class causes class to explode, and has inevitably resulted in a large amount of memory leak issues.And excessive packaging when due to using,
Want to find callback code at calling, it is even more extremely difficult, it is very unfriendly to developer.
And the above problem can be effectively improved by being realized using task template.In one embodiment of the invention, above-mentioned
In method, task is network request task；Choose the task template that matches according to mission bit stream, and according to mission bit stream and
The task template of selection generates task：The address URL of network request and call back function are encapsulated by network request template
For a network request.
The format for moving into a new network request can be as follows：Req (url ... fn).Here, call back function fn
It can use lambda to realize, the characteristic of lambda already explained above, it can easily be seen that at calling, it can be direct
Callback code is found, for developer, the code for taking over other developers exploitation is also easier to read.
In one embodiment of the invention, in the above method, network request template is quiet by the network request of load
What state library obtained.Here network request static library can be a dll, client using when loaded.
In one embodiment of the invention, in the above method, network request template includes following one or more：From
The specialization template of memory read data；The specialization template of data is read from file；To the specialization template of memory write-in data；Xiang Wen
The specialization template of part write-in data.
In the present embodiment, it is contemplated that the optimization of performance is respectively provided with phase for four class average case in network request
The specialization template answered, being capable of significant increase performance through practice.
In one embodiment of the invention, in the above method, task template includes variable element template；According to mission bit stream
Generating task with the task template of selection includes：Type extraction is carried out to mission bit stream, converts universal class for mission bit stream
Several parameters；According to several parameters and variable element template generation task.
Variable element template is the new features that c++11 is provided, and support is extensive, and common templates may only take fixed quantity
Template parameter, and by variable element template, it theoretically can receive any number of template parameter.And as mission bit stream
Parameter can be it is a plurality of types of, can by its by type extraction be converted to universal class.
