Detailed Description

template<typename Req, typename Res, typename BaseClientT = BaseClient<>>
class iox::popo::ClientImpl< Req, Res, BaseClientT >

The ClientImpl class implements the typed client API.

Note

Not intended for public usage! Use the Client instead!

Constructor & Destructor Documentation

ClientImpl()

template<typename Req, typename Res, typename BaseClientT = BaseClient<>>

iox::popo::ClientImpl< Req, Res, BaseClientT >::ClientImpl ( const capro::ServiceDescription & service, const ClientOptions & clientOptions = {} )

explicitnoexcept

Constructor for a client.

Parameters

[in]	service	is the ServiceDescription for the new client
[in]	clientOptions	like the queue capacity and queue full policy by a client

Member Function Documentation

loan()

template<typename Req, typename Res, typename BaseClientT = BaseClient<>>

template<typename... Args>

cxx::expected< Request< Req >, AllocationError > iox::popo::ClientImpl< Req, Res, BaseClientT >::loan ( Args &&... args )

noexcept

Get a Request from loaned shared memory and construct the data with the given arguments.

Parameters

[in]

args

Arguments used to construct the data.

Returns

An instance of the Request that resides in shared memory or an error if unable to allocate memory to loan.

The loaned Request is automatically released when it goes out of scope.

send()

template<typename Req, typename Res, typename BaseClientT = BaseClient<>>

cxx::expected< ClientSendError > iox::popo::ClientImpl< Req, Res, BaseClientT >::send ( Request< Req > && request )

overridenoexcept

Sends the given Request and then releases its loan.

Parameters

request

to send.

Returns

Error if sending was not successful

take()

template<typename Req, typename Res, typename BaseClientT = BaseClient<>>

cxx::expected< Response< const Res >, ChunkReceiveResult > iox::popo::ClientImpl< Req, Res, BaseClientT >::take ( )

noexcept

Take the Response from the top of the receive queue.

Returns

Either a Response or a ChunkReceiveResult.

The Response takes care of the cleanup. Don't store the raw pointer to the content of the Response, but always the whole Response.
