Detailed Description

A contract for the handler that will handle the LiveViewCamera namespace messages coming from the IPC client.

Member Function Documentation

clearCamera()

void alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::clearCamera

(

)

Sends a clearCamera IPC message to the IPC client.

create()

static std::shared_ptr<LiveViewCameraHandler> alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::create ( std::shared_ptr< IPCHandlerRegistrationInterface >  ipcHandlerRegistrar, std::shared_ptr< LiveViewCameraHandlerInterface >  liveViewCameraComponent  )

static

Create an instance of LiveViewCameraHandler

Parameters

ipcHandlerRegistrar	Used to register LiveViewCameraHandler.
liveViewCameraComponent	Handles the parsed LiveViewCamera payloads.

Returns

Shared pointer to LiveViewCameraHandler

doShutdown()

void alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::doShutdown ( )

overridevirtual

Prepares/enables this object to be deleted. This should be the last function called on this object prior to deleting (or resetting) its shared_ptr.

Warning

• Attempting to call functions on this object after calling shutdown() can result in undefined behavior.
• Neglecting to call shutdown() on this object can result in resource leaks or other undefined behavior.

Implements alexaClientSDK::avsCommon::utils::RequiresShutdown.

registerHandlers()

void alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::registerHandlers

(

)

Register this handler for its namespace and its methods for the corresponding namespace functions.

renderCamera()

void alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::renderCamera

(

const std::string &

startLiveViewPayload

)

Sends a renderCamera IPC message to the IPC client.

Parameters

startLiveViewPayload

The payload of the corresponding StartLiveView directive.

setCameraState()

void alexaClientSDK::sampleApplications::ipcServerSampleApp::ipc::LiveViewCameraHandler::setCameraState

(

const std::string &

cameraState

)

Sends a setCameraState IPC message to the IPC client.

Parameters

cameraState

Enumerated live view camera state.
