Detailed Description

RPC Function result for void return value.

Member Typedef Documentation

CallbackFunctionType

typedef function<void(RPCResult<void>&) kanzi::connect::RPCResultImpl< void >::CallbackFunctionType)

Callback type.

Constructor & Destructor Documentation

RPCResultImpl()

kanzi::connect::RPCResultImpl< void >::RPCResultImpl ( RPCTypes::CommHandle handle )

inline

C++ constructs - initializes the object.

Parameters

handle

the handle for the operation.

Member Function Documentation

addCallback()

RPCTypes::CallbackFunctionSubscriptionToken kanzi::connect::RPCResultImpl< void >::addCallback ( CallbackFunctionType callback )

inline

Add callback.

Parameters

callback

to be called when value is available.

Returns

subscription that can be used to cancel the request.

completeIfTimedOut()

bool kanzi::connect::RPCResultImpl< void >::completeIfTimedOut ( const chrono::steady_clock::time_point & now )

inline

Completes the operation if it has been timed out.

Returns

true if timed out

completeLinkBroken()

void kanzi::connect::RPCResultImpl< void >::completeLinkBroken ( )

inline

Completes RPC with link broken status.

doComplete()

void kanzi::connect::RPCResultImpl< void >::doComplete ( int32_t rpcresult = GenericRPCReplyMessage::RPC_RESULT_OK )

inline

Completes the RPC result promise.

Parameters

rpcresult

low level rpc return value.

getValue()

void kanzi::connect::RPCResultImpl< void >::getValue ( )

inline

Gets the value.

Note

can be called only once.

invokeCallbacks()

void kanzi::connect::RPCResultImpl< void >::invokeCallbacks ( )

inlineprotected

Invokes all callbacks.

There can be any number of them configured for a single RPC call completion.

allow callback to get removed from callback itself. If new callback is added from callback it won't be called.

removeCallback()

void kanzi::connect::RPCResultImpl< void >::removeCallback ( RPCTypes::CallbackFunctionSubscriptionToken token )

inline

Removes callback from the callback array.

Parameters

token

callback to remove, token returned by addCallback function.
