QGrpcClientInterceptorManager Class

Member Function Documentation

QGrpcClientInterceptorManager::QGrpcClientInterceptorManager()

Constructs an empty QGrpcClientInterceptorManager object.

[noexcept] QGrpcClientInterceptorManager::~QGrpcClientInterceptorManager()

Destroys the QGrpcClientInterceptorManager object.

void QGrpcClientInterceptorManager::registerInterceptor(std::shared_ptr<QGrpcClientInterceptor> next)

Registers a QGrpcClientInterceptor interceptor.

Places the next interceptor at the beginning of the interceptor chain. Interceptors are executed in reverse order of registration. For instance,

manager.registerInterceptor(myInterceptor1);
manager.registerInterceptor(myInterceptor2);

will result in:

myInterceptor2 -> myInterceptor1 -> Qt GRPC operation

order of execution.

void QGrpcClientInterceptorManager::registerInterceptors(std::vector<std::shared_ptr<QGrpcClientInterceptor>> nextInterceptors)

Registers multiple QGrpcClientInterceptor interceptors.

Adds the given interceptors to the start of the interceptor chain. While execution occurs in the reverse order of registration, the original order in the nextInterceptors vector is maintained, for example:

manager.registerInterceptor(myInterceptor1);
manager.registerInterceptors({myInterceptor2, myInterceptor3});

will result in:

myInterceptor2 -> myInterceptor3 -> myInterceptor1 -> Qt GRPC operation

order of execution.

template <typename T> void QGrpcClientInterceptorManager::run(QGrpcInterceptorContinuation<T> &finalCall, typename QGrpcInterceptorContinuation<T>::ReplyType response, std::shared_ptr<QGrpcChannelOperation> operation, size_t pos = 0)

Executes the Qt GRPC interceptors in the chain for a specific QGrpcOperation type.

The process initiates with the interceptor located at position pos in the QGrpcClientInterceptor chain. Both response and operation parameters are relayed to the QGrpcClientInterceptor::intercept() method. Upon reaching the end of the interceptor chain, the finalCall is invoked.
