Detailed Description
As background art shows, in the existing method for processing data by using a producer model and a consumer model, when a producer thread generates corresponding resource data, it is necessary to wait for a consumer thread to query the corresponding resource data in a polling manner, so that the queried resource data can be processed, and the problem of poor real-time performance exists.
In order to solve the above problems in the prior art, in the technical scheme adopted by the embodiment of the invention, the corresponding resource data is generated by the producer thread, and the consumer thread is activated to process the resource data when the resource data generated by the consumer thread demand is determined.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
FIG. 1 is a flow chart illustrating a method of inter-process communication in an embodiment of the invention. As shown in fig. 1, the inter-process communication method suitable for recording an object to be recorded displayed on a screen interface may specifically include the following operations:
step S101: when a producer thread produces resource data, it is determined whether a consumer thread requires the resource data.
In a particular implementation, the producer thread is a thread that produces resource data, and the consumer thread is a thread that processes the resource data produced by the producer thread. The number of the producer threads and the consumer threads can be set to be one or more according to actual needs.
Step S102: when it is determined that the resource data is needed by the consumer thread, activating the consumer thread to process the resource data.
In specific implementation, when a producer thread generates corresponding resource data and determines the resource data generated by a consumer thread demand, the consumer thread can be activated to process the resource data, and compared with a polling mode, the real-time performance of resource data processing can be improved.
A data processing method in the embodiment of the present invention will be described in further detail with reference to fig. 2 and the drawings.
Fig. 2 shows a flow chart of a data processing method in an embodiment of the invention. Referring to fig. 2, a data processing method in the implementation of the present invention is suitable for processing data by using a producer-consumer model, and may specifically include the following steps.
Step S201: the producer thread produces corresponding resource data.
In a specific implementation, the manner in which the producer thread generates the corresponding resource data may be set according to actual needs. The number of the producer threads can be one or more, the same producer thread can generate the same or different resource data according to actual needs, and the resource data generated by different producer threads can be the same or different.
Step S202: judging whether the consumer demand queue has demand information of the resource data or not; when the judgment result is yes, step S203 may be performed; otherwise, step S204 may be performed.
In an embodiment of the present invention, in order to distinguish different resource data, when the resource data is generated, a preset rule may be used to name the generated resource data, that is, the resource data generated by the producer thread is named resource data. Meanwhile, the resource data required by the consumer thread is named resource data. In other words, the consumer thread processes only the corresponding named resource data.
In one implementation of the present invention, when a consumer needs resource data and cannot immediately acquire the corresponding resource data, the consumer thread may generate corresponding resource data need information and add the generated resource data need information to a preset consumer need queue, so that when the corresponding resource data is generated, the corresponding resource data may be timely acquired and processed. The resource data demand information generated by the consumer thread includes information of corresponding resource data, such as names of named resource data.
In a specific implementation, the resource data requirement information in the consumer requirement queue is requirement information of resource data of one consumer thread, and may also be requirement information of resource data of more than two consumer threads, and a person skilled in the art may set the requirement information according to actual needs, which is not limited herein. When a plurality of consumer threads are provided, the demand information of the resource data generated by the consumer threads further includes the information of the consumer threads, so that the information of the consumer threads and the resource data demanded by the consumer threads can be determined according to the demand information of the resource data in the consumer demand queue.
Step S203: and activating the consumer thread to process the resource data.
In specific implementation, when determining that a consumer thread needs generated resource data, determining information of a corresponding consumer thread according to corresponding resource data demand information in a consumer demand queue, and activating the corresponding consumer thread, so that the corresponding consumer thread can acquire the generated resource data and perform corresponding processing. And when the consumer thread acquires the corresponding resource data, deleting the demand information of the corresponding resource data in the consumer demand queue.
Step S204: and putting the resource data into a producer production queue.
In a specific implementation, when it is determined that there is no corresponding resource data requirement information in the consumer requirement queue, that is, the generated resource data is not required by the consumer thread. At this time, the producer thread may place the generated resource data into a corresponding producer production queue to wait for a corresponding consumer to obtain and process the corresponding resource data.
The data processing method in the embodiment of the present invention is described in detail in the above-mentioned processing procedure corresponding to the generation of the corresponding resource data by the producer thread, and will be further described in detail in the following with reference to fig. 3 from the time when the consumer thread requires the resource data.
Referring to fig. 3, in order to enable a consumer thread to timely obtain corresponding resource data for processing, the data processing method in the embodiment of the present invention may further include:
step S301: when the consumer needs the corresponding resource data, judging whether the corresponding resource data exists in the producer queue; when the judgment result is yes, step S302 may be performed; otherwise, step S303 may be performed.
In a specific implementation, when the resource data generated by the producer cannot find the corresponding consumer thread for processing, the producer thread may store the corresponding resource data in a preset producer production queue. The resource data in the producer production queue may be resource data generated by one producer thread, or may include resource data generated by more than two producer threads.
In particular implementations, when a consumer thread needs resource data, it may be determined that corresponding resource data has been generated by querying a producer production queue for the presence of corresponding resource data.
Step S302: and the consumer thread takes out the corresponding resource data from the producer production queue for processing.
In specific implementation, when determining that the corresponding resource data exists in the producer production queue, the consumer thread may take out the corresponding resource data from the producer production queue and perform corresponding processing.
Step S303: and generating corresponding resource data demand information and adding the resource data demand information into a consumer demand queue.
In specific implementation, when determining that the corresponding resource data does not exist in the producer queue, the consumer thread may generate demand information of the corresponding resource data, and place the demand information into the consumer demand queue, so that when the corresponding resource data is generated, the corresponding resource data may be obtained in time.
In specific implementation, when the requirement information of the generated resource data is put into the corresponding consumer requirement queue, the consumer thread enters a waiting state to wait for the generation of the corresponding resource data within a preset time period, and when the corresponding resource data is generated, the corresponding resource data can be acquired and processed. The preset time can be set according to actual needs.
In an implementation, when a producer thread produces corresponding resource data within a preset time, a consumer thread waits for success. At this point, the consumer thread may obtain and process the corresponding resource data. Meanwhile, the corresponding resource data demand information in the consumer demand queue is deleted. When no corresponding resource data is generated within a preset time, the consumer thread waits for a failure. Meanwhile, the corresponding resource data demand information in the queue in the consumer demand is also deleted.
The method in the embodiment of the present invention is described in detail above, and the apparatus corresponding to the method will be described below.
