Problems solved by technology

[0002] The traditional openharmony Hongmeng SA (system ability) service is internally implemented using a binder driver. The sa service can provide fa and pa (feature ability, particle ability) cross-process call capabilities by registering to samger, but sa itself cannot actively send messages give pa, fa(feature ability, particleability)

Embodiment

[0024] as Figure 1-2 As shown, the eventBusSA system service based on Hongmeng L2 rich device includes multiple Apps, evevtBus system services, and brokers;

[0025] The publishing function of the sending end of the App is configured to provide publishing functionality through the SA service registered to THE SAMGR via IPC calls;

[0026] The evevtBus system service receives the relevant message of the App and forwards it to the broker;

[0027] The receiver of the app subscribes to the broker by socket.

[0028] The IPC call is implemented via binder.

[0029] The App includes characteristic ability as well as particle ability.

[0030] The characteristic ability is configured to exist the ability of the relevant page, providing the user with the ability to interact.

[0031] The Particle ability is configured as an interface-free capability, supporting service ability and dataability templates.

[0032]The SA is configured as a system service-level process that belongs to the ba...

Abstract

The invention discloses an eventBus SA system service based on a swan Mongolia L2 rich device. The eventBus SA system service comprises a plurality of Apps, an eventBus system service and a broker. The release function of the transmitting end of the App is configured to provide a release function by calling SA service registered to the SAMGR through the IPC; after the evvtBus system service receives the related message of the App, the evvtBus system service forwards the related message to the broker; the receiving end of the App subscribes to the message from the broker in a socket mode, the App at the receiving end only needs to subscribe to the message, and the App at the sending end sends the corresponding message, so that internal message circulation can be completed.

Description

Technical field [0001] The present invention relates to the field of eventBusSA system services, in particular to the eventBusSA system services based on Hongmeng L2 rich devices. Background [0002] The traditional openharmony Hongmeng SA (system ability) service, internally using binder driver implementation, sa service by registering in the summer can provide fa, pa (feature ability, particle ability) cross-process call capability, but sa itself can not actively send messages to pa, fa (feature ability, particleability)。 Using the eventBussa system service, it not only provides the ability of ordinary pa, fa (feature ability, particleability) cross-process invocation (communication), but also has the ability of sa (system ability) to communicate backwards to pa, fa (featureability, particle ability). Provides a complete internal event broadcast loop mechanism for the end-side device. Contents of the Invention [0003] In view of the description, the object of the present inve...
