Member Function Documentation

◆ close()

void yarp::os::impl::PortCoreOutputUnit::close ( )

inlineoverridevirtual

Reimplemented from yarp::os::impl::ThreadImpl.

Definition at line 70 of file PortCoreOutputUnit.h.

◆ getCarrierParams()

void PortCoreOutputUnit::getCarrierParams ( yarp::os::Property & params )

overridevirtual

Parameters

[out]

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 433 of file PortCoreOutputUnit.cpp.

◆ getOutPutProtocol()

OutputProtocol * PortCoreOutputUnit::getOutPutProtocol ( )

Definition at line 440 of file PortCoreOutputUnit.cpp.

◆ getRoute()

Route PortCoreOutputUnit::getRoute ( )

overridevirtual

Returns: the route (sender, receiver, carrier) associated with this connection

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 245 of file PortCoreOutputUnit.cpp.

◆ isBusy()

bool PortCoreOutputUnit::isBusy ( )

overridevirtual

Returns: true if the connection is currently in use.

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 421 of file PortCoreOutputUnit.cpp.

◆ isFinished()

bool yarp::os::impl::PortCoreOutputUnit::isFinished ( )

inlineoverridevirtual

Returns: true if no further communication will occur using this connection

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 76 of file PortCoreOutputUnit.h.

◆ isOutput()

bool yarp::os::impl::PortCoreOutputUnit::isOutput ( )

inlineoverridevirtual

Returns: true if this is an output connection

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 64 of file PortCoreOutputUnit.h.

◆ run()

void PortCoreOutputUnit::run ( )

overridevirtual

The body of a thread managing background sends.

Reimplemented from yarp::os::impl::ThreadImpl.

Definition at line 77 of file PortCoreOutputUnit.cpp.

◆ runSingleThreaded()

void PortCoreOutputUnit::runSingleThreaded ( )

virtual

Perform send operations without a separate thread.

Definition at line 119 of file PortCoreOutputUnit.cpp.

◆ send()

void * PortCoreOutputUnit::send	(	const yarp::os::PortWriter &	writer,
		yarp::os::PortReader *	reader,
		const yarp::os::PortWriter *	callback,
		void *	tracker,
		const std::string &	envelope,
		bool	waitAfter,
		bool	waitBefore,
		bool *	gotReply
	)

overridevirtual

Send a message on the connection.

Does nothing for an input connection.

Parameters

writer	the message the send
reader	an optional receiver for a reply
callback	an optional receiver for PortWriter::onCommencement and PortWriter::onCompletion calls
tracker	an opaque pointer to an object doing memory management for the message. Once this pointer is passed to the send() method, it is "owned" until returned by a future call to send(), or by a call to takeTracker().
envelope	some optional text to pass along with the message
waitAfter	true if we should wait for the send to complete before the method returns
waitBefore	true if we should wait for any in-progress send to complete before stating this one @parm gotReply if non-nullptr, this variable will be set to true if a reply was received

Returns: nullptr, or a tracker for a previous send operation that is no longer in progress. The tracker is an opaque pointer passed in via a previous call to send(). Once it is returned, it is the caller's responsibility to manage any memory associated with the message.

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 346 of file PortCoreOutputUnit.cpp.

◆ setCarrierParams()

void PortCoreOutputUnit::setCarrierParams ( const yarp::os::Property & params )

overridevirtual

Set arbitrary parameters for this connection.

Parameters

params the parameters to set

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 426 of file PortCoreOutputUnit.cpp.

◆ start()

bool PortCoreOutputUnit::start ( )

overridevirtual

Prepare to serve this output.

A thread will start if a call to send() has been made with options that require a thread.

Reimplemented from yarp::os::impl::ThreadImpl.

Definition at line 53 of file PortCoreOutputUnit.cpp.

◆ takeTracker()

void * PortCoreOutputUnit::takeTracker ( )

overridevirtual

Reacquire a tracker previously passed via send().

This method may need to wait a send operation to complete before the tracker can be safely accessed.

Returns: the opaque tracker pointer passed to a previous call to send(), or nullptr if there is no such tracker. Once the tracker has been returned, calling this method again will return nullptr.

Reimplemented from yarp::os::impl::PortCoreUnit.

Definition at line 409 of file PortCoreOutputUnit.cpp.
