详细描述

QAbstractGrpcClient provides a set of functions for client classes generated out of protobuf services. QAbstractGrpcClient enforces thread safety for startStream () and call() methods of generated clients. The methods QAbstractGrpcClient::call() and QAbstractGrpcClient::startStream () should only be called by the generated client classes.

成员函数文档编制

void QAbstractGrpcClient:: attachChannel (const std::shared_ptr < QAbstractGrpcChannel > & channel )

Attaches channel to client as transport layer for gRPC.

Parameters and return values will be serialized to the channel in a format it supports.

注意： 警告 : Qt GRPC doesn't guarantee thread safety on the channel level. You have to invoke the channel-related functions on the same thread as QAbstractGrpcClient .

注意： setter 函数对于特性 channel .

`[since 6.7]` const std::shared_ptr < QAbstractGrpcChannel > &QAbstractGrpcClient:: channel ()

Returns the channel attached to this client.

注意： Getter function for property channel.

该函数在 Qt 6.7 引入。

`[signal, since 6.7]` void QAbstractGrpcClient:: channelChanged ()

Indicates that a new channel is attached to the client.

注意： 通知程序信号对于特性 channel .

该函数在 Qt 6.7 引入。

`[signal]` void QAbstractGrpcClient:: errorOccurred (const QGrpcStatus & status )

Indicates that an error occurred during serialization.

This signal is emitted when an error with status occurs in the channel or during serialization.

另请参阅 QGrpcOperation::errorOccurred .

`[protected]` template <typename ParamType, typename StreamType> std::shared_ptr < StreamType > QAbstractGrpcClient:: startStream ( QLatin1StringView method , const QProtobufMessage & arg , const QGrpcCallOptions & options )

Starts the stream method 的 StreamType type with the message argument arg to the attached channel.

Uses options argument to set additional parameter in the stream communication.

The implementation is only available for StreamType : QGrpcServerStream , QGrpcClientStream ，和 QGrpcBidirStream .
