Member Function Documentation

◆ accept()

int ShmemHybridStream::accept ( )

Definition at line 52 of file ShmemHybridStream.cpp.

◆ beginPacket()

void ShmemHybridStream::beginPacket ( )

overridevirtual

Mark the beginning of a logical packet.

This is a unit that should be treated in an atomic fashion by YARP. If any part is corrupted, the whole should be dropped.

Implements yarp::os::TwoWayStream.

Definition at line 206 of file ShmemHybridStream.cpp.

◆ close()

void ShmemHybridStream::close ( )

overridevirtual

Terminate the stream.

Implements yarp::os::InputStream.

Definition at line 156 of file ShmemHybridStream.cpp.

◆ endPacket()

void ShmemHybridStream::endPacket ( )

overridevirtual

Mark the end of a logical packet (see beginPacket).

Implements yarp::os::TwoWayStream.

Definition at line 210 of file ShmemHybridStream.cpp.

◆ getInputStream()

yarp::os::InputStream & ShmemHybridStream::getInputStream ( )

overridevirtual

Get an InputStream to read from.

Returns: the InputStream associated with this object.

Implements yarp::os::TwoWayStream.

Definition at line 185 of file ShmemHybridStream.cpp.

◆ getLocalAddress()

const yarp::os::Contact & ShmemHybridStream::getLocalAddress ( ) const

overridevirtual

Get the address of the local side of the stream.

Returns: the address of the local side of the stream. The address will be tagged as invalid if the stream is not set up.

Implements yarp::os::TwoWayStream.

Definition at line 214 of file ShmemHybridStream.cpp.

◆ getOutputStream()

yarp::os::OutputStream & ShmemHybridStream::getOutputStream ( )

overridevirtual

Get an OutputStream to write to.

Returns: the InputStream associated with this object.

Implements yarp::os::TwoWayStream.

Definition at line 190 of file ShmemHybridStream.cpp.

◆ getRemoteAddress()

const yarp::os::Contact & ShmemHybridStream::getRemoteAddress ( ) const

overridevirtual

Get the address of the remote side of the stream.

Returns: the address of the remote side of the stream. The address will be tagged as invalid if the stream is not set up.

Implements yarp::os::TwoWayStream.

Definition at line 219 of file ShmemHybridStream.cpp.

◆ interrupt()

void ShmemHybridStream::interrupt ( )

overridevirtual

Interrupt the stream.

If the stream is currently in a blocked state, it must be unblocked.

Reimplemented from yarp::os::InputStream.

Definition at line 163 of file ShmemHybridStream.cpp.

◆ isOk()

bool ShmemHybridStream::isOk ( ) const

overridevirtual

Check if the stream is ok or in an error state.

Returns: true iff the stream is ok

Implements yarp::os::InputStream.

Definition at line 195 of file ShmemHybridStream.cpp.

◆ open()

int ShmemHybridStream::open	(	const yarp::os::Contact &	yarp_address,
		bool	sender
	)

Definition at line 23 of file ShmemHybridStream.cpp.

◆ read()

yarp::conf::ssize_t ShmemHybridStream::read ( yarp::os::Bytes & b )

overridevirtual

Read a block of data from the stream.

Should block and wait for data.

Parameters

b[out] the block of data to read to

Returns: the number of bytes read, or -1 upon error

Implements yarp::os::InputStream.

Definition at line 176 of file ShmemHybridStream.cpp.

◆ reset()

void ShmemHybridStream::reset ( )

overridevirtual

Reset the stream.

Implements yarp::os::TwoWayStream.

Definition at line 200 of file ShmemHybridStream.cpp.

◆ write()

void ShmemHybridStream::write ( const yarp::os::Bytes & b )

overridevirtual

Write a block of bytes to the stream.

Parameters

b	the bytes to write

Implements yarp::os::OutputStream.
