Detailed Description

Interface for objects with a file descriptor, providing a virtual method to be called when system calls such as select, poll, or epoll indicate an event is pending on the file descriptor.

Constructor & Destructor Documentation

~Polled()

virtual nidas::core::Polled::~Polled ( )

inlinevirtual

Member Function Documentation

getFd()

virtual int nidas::core::Polled::getFd ( ) const

pure virtual

Implemented in nidas::core::RemoteSerialConnection, nidas::core::RemoteSerialListener, nidas::core::SensorHandler::PolledDSMSensor, and nidas::core::SensorHandler::NotifyPipe.

handlePollEvents()

virtual bool nidas::core::Polled::handlePollEvents ( uint32_t events )

pure virtual

Returns

: true: read consumed all available data, false otherwise. This return value is required for edge-triggered polling with epoll, since a read event won't be re-triggered on a file descriptor until all available data is read.

Implemented in nidas::core::RemoteSerialConnection, nidas::core::RemoteSerialListener, nidas::core::SensorHandler::PolledDSMSensor, and nidas::core::SensorHandler::NotifyPipe.

Referenced by nidas::core::SensorHandler::run().
