Please refer to FIG. 1 , which is a block diagram of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 includes a data notification device 110, a memory 120, and a processor 130.

The memory 120 and the processor 130 are electrically connected directly or indirectly to each other to implement data transmission or interaction. For example, the components can be electrically connected to one another via one or more communication buses or signal lines. The data notification device 110 includes at least one software function module that can be stored in the memory 120 or in an operating system (OS) of the electronic device 100 in the form of software or firmware. The processor 130 is configured to execute executable modules stored in the memory 120, such as software function modules, computer programs, and the like included in the data notification device 110.

The memory 120 may be, but not limited to, a random access memory (RAM), a read only memory (ROM), and a programmable read-only memory (PROM). Erasable Programmable Read-Only Memory (EPROM), Electric Erasable Programmable Read-Only Memory (EEPROM), and the like. The memory 120 is configured to store a program, and the processor 130 executes the program after receiving an execution instruction.

The processor 130 may be an integrated circuit chip with signal processing capabilities. The above processor may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; or may be a digital signal processor (DSP), an application specific integrated circuit (ASIC) ), Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The methods, steps, and logical block diagrams disclosed in the embodiments of the present disclosure may be implemented or carried out. The general purpose processor may be a microprocessor or the processor or any conventional processor or the like.

In the embodiment of the present disclosure, the electronic device 100 includes a software model, where the software model includes a data layer and a view layer, wherein the data layer is configured to perform data processing and conversion, and the view layer is configured to be configured according to The data in the data layer is displayed in a software view.

Please refer to FIG. 2. FIG. 2 is a flowchart of a data notification method applied to the software model. The method includes the following steps.

In step S110, the data layer detects data change of the target data point, and generates a data change message.

In the embodiment of the present disclosure, the software model is a new software model formed by removing the control layer from the MVC model. Since the control layer in the MVC hierarchy is removed from the software model, the original control layer is The data processing business logic is transferred to the data layer for processing, that is, the data layer is mainly responsible for the work of two parts, one is the data change acquisition of the target data point, and the second is to convert the data into the view layer. The required data format, that is, the data change information sent by the data layer to the view layer is the information after the format conversion.

After the data layer completes the acquisition and conversion of the original data, the data change message of the data is subsequently sent to the view layer through step S120.

The target data point can be understood as a variable that needs to be monitored, and the data layer monitors the target data point in real time to detect the target data point, and the data of the target data point is detected to be changed. A data change message is generated and sent to the view layer.

In addition, optionally, the data change of the target data point may be detected by: when the data layer receives the data change event for the target data point, generating data change information. For example, when the data of the target data point is changed, a data change event indicating data change is sent to the data layer, and the data change event may be a change command or data change prompt information, etc., and the data layer receives the data. After a data change event, if the data of the target data point has been changed, a data change information is generated and sent to the view layer.

Alternatively, the data change of the target data point may be detected by: the data layer periodically detecting and recording the data value of the target data point, and currently detecting the current data value of the target data point and the last recorded When the data values do not match, data change information is generated. For example, the data layer periodically detects the data value of the target data point, for example, the period is 1 s, and the data layer interval detects the target data point by 1 s, if the target data point is detected and recorded in the last second. The data value is 1, and the data value of the target data point detected in this second is 2, indicating that the current data value of the target data point is inconsistent with the last recorded data value, that is, the data of the target data point is changed. Generate a data change message to send to the view layer.

Alternatively, the data change of the target data point may be detected by: when the data layer detects that the data value of the target data point is changed from the first preset value to the second preset value, the data change information is generated. For example, the first preset value is 0, and the second preset value is 1. Of course, the first preset value and the second preset value may be defined according to requirements, when the data layer detects that the data of the target data point changes from 0 to 0. When it is 1, it means that the data of the target data point has changed, and a data change information is generated and sent to the view layer.

Step S120, the data layer sends the data change message to a view layer that registers to monitor the change of the target data point.

In an embodiment of the present disclosure, the software model includes a set of listeners, and the plurality of view layers monitor changes of the target data points through the set of the listeners.

In the embodiment of the present disclosure, in order to reduce the hierarchical relationship and remove the control layer, a listener is designed in the software model. In order to solve a plurality of application scenarios in which the view layer monitors changes of the same target data point, the listener is designed in the form of a set, such that the plurality of view layers monitor the target data through the set of the listeners. With the change of the point, it is possible to save the listening requests of multiple view layers in the set of the listeners.

After the data layer generates the data change message through step S110, the data layer traverses the set of the listeners, and sends the data change message to a view layer that registers to listen to the change of the target data point. That is to say, one view layer monitors the target data point through multiple listeners, and the view layer is associated with a plurality of corresponding listeners of the intercept target data point in advance, thereby generating data change information after the data layer is generated. The set of listeners is traversed to find a suitable listener to send data change information to the view layer.

Optionally, each of the listeners is configured with a corresponding priority level, and the data layer may further select a priority from the highest priority listener in the set of listeners according to the priority level of the respective listeners. The lowest listener traverses and sends the data change information to a view layer that registers to listen for changes in the target data point. For example, when the data is changed, the data change information may be sequentially transmitted according to the priority of the listener, that is, the listener with a high priority is called first, and is used to send the data change information.

Optionally, in the embodiment of the present disclosure, the listener is an interface protocol between the data layer and the view layer, and the interface protocol includes an interface function, for example, in the embodiment of the present disclosure. In the interface protocol of the listener, an interface function of onXXXDataChange is designed (where XXX represents the name of the software model). When the data layer has data changes, the data change information is exposed to the view through the interface function onXXXDataChange. a layer for the view layer to call back the onXXXDataChange interface function to obtain data change information sent by the data layer.

Based on the above design, a form of an interface is designed inside each software model to expose a data change message inside the data layer, thereby effectively reducing the coupling relationship between the data layer and the view layer, and improving the software. Scalability and maintainability.

Step S130, the view layer performs corresponding view switching or display according to the received data change message.

In the embodiment of the present disclosure, since the control layer is reduced, the logic of the switching view performed by the control layer is transplanted to the view layer, and the trigger condition of the switching view is changed to the data change message of the data layer to perform corresponding triggering.

Each view in the view layer is configured to carry a part of data. In the embodiment of the present disclosure, the view interface needs to be exposed in the view layer, and then the target data point to be monitored is registered in the view layer by calling the register function. The software model is thus able to obtain the reference relationship of the view layer.

Since the data layer has defined the notification interface of the data change message, in the embodiment of the present disclosure, the view layer receives the data change information of the data layer by rewriting the interface function. However, if the view layer needs to listen to multiple target data points, it is necessary to implement a corresponding interface for each target data point, and establish a relationship between the view layer and the data layer, so that the view layer passes The interface acquires data change information sent by the data layer.

For example, through the above steps, the data layer has established an association with the view layer through an interface. Since the view layer has previously registered the intercept target data point, when receiving the data change message, the view layer actively triggers the onXXXDataChange function to execute the corresponding view switch or display logic in the onXXXDataChange function.
