Detailed Description

A helper for recording entire message/reply transactions.

Constructor & Destructor Documentation

◆ ConnectionRecorder()

yarp::os::impl::ConnectionRecorder::ConnectionRecorder ( )

Definition at line 14 of file ConnectionRecorder.cpp.

Member Function Documentation

◆ appendBlock()

void yarp::os::impl::ConnectionRecorder::appendBlock	(	const char *	data,
		size_t	len
	)

overridevirtual

Send a block of data to the network connection.

Since communication may not happen immediately, or may happen multiple times, a copy of this data is made. If you know the block of data will remain valid, and it is a large block of data, please call ConnectionWriter::appendExternalBlock instead.

Parameters

data	the start of the data block
len	the length of the data block

Implements yarp::os::ConnectionWriter.

Definition at line 196 of file ConnectionRecorder.cpp.

◆ appendExternalBlock()

void yarp::os::impl::ConnectionRecorder::appendExternalBlock	(	const char *	data,
		size_t	len
	)

overridevirtual

Send a block of data to the network connection, without making a copy.

If you are not confident that the block of data will remain valid throughout transmission, call ConnectionWriter::appendBlock instead.

Parameters

data	the start of the data block
len	the length of the data block

Implements yarp::os::ConnectionWriter.

Definition at line 244 of file ConnectionRecorder.cpp.

◆ appendFloat32()

void yarp::os::impl::ConnectionRecorder::appendFloat32 ( yarp::conf::float32_t data )

overridevirtual

Send a representation of a 32-bit floating point number to the network connection.

Parameters

data	the floating point number to send

Implements yarp::os::ConnectionWriter.

Definition at line 226 of file ConnectionRecorder.cpp.

◆ appendFloat64()

void yarp::os::impl::ConnectionRecorder::appendFloat64 ( yarp::conf::float64_t data )

overridevirtual

Send a representation of a 64-bit floating point number to the network connection.

Parameters

data	the floating point number to send

Implements yarp::os::ConnectionWriter.

Definition at line 232 of file ConnectionRecorder.cpp.

◆ appendInt16()

void yarp::os::impl::ConnectionRecorder::appendInt16 ( std::int16_t data )

overridevirtual

Send a representation of a 16-bit integer to the network connection.

Parameters

data	the integer to send

Implements yarp::os::ConnectionWriter.

Definition at line 208 of file ConnectionRecorder.cpp.

◆ appendInt32()

void yarp::os::impl::ConnectionRecorder::appendInt32 ( std::int32_t data )

overridevirtual

Send a representation of a 32-bit integer to the network connection.

Parameters

data	the integer to send

Implements yarp::os::ConnectionWriter.

Definition at line 214 of file ConnectionRecorder.cpp.

◆ appendInt64()

void yarp::os::impl::ConnectionRecorder::appendInt64 ( std::int64_t data )

overridevirtual

Send a representation of a 64-bit integer to the network connection.

Parameters

data	the integer to send

Implements yarp::os::ConnectionWriter.

Definition at line 220 of file ConnectionRecorder.cpp.

◆ appendInt8()

void yarp::os::impl::ConnectionRecorder::appendInt8 ( std::int8_t data )

overridevirtual

Send a representation of a 8-bit integer to the network connection.

Parameters

data	the integer to send

Implements yarp::os::ConnectionWriter.

Definition at line 202 of file ConnectionRecorder.cpp.

◆ appendText()

void yarp::os::impl::ConnectionRecorder::appendText	(	const std::string &	str,
		const char	terminate
	)

overridevirtual

Send a terminated string to the network connection.

The lenght of string is not specified in advance, therefore the reader should read until the terminating character is found.

Parameters

str	the string to send
terminate	the terminating character to use

Implements yarp::os::ConnectionWriter.

Definition at line 238 of file ConnectionRecorder.cpp.

◆ convertTextMode()

bool yarp::os::impl::ConnectionRecorder::convertTextMode ( )

overridevirtual

Reads in a standard description in text mode, and converts it to a standard description in binary.

Useful if you only operate on the binary description usually, and just want to permit text mode for command-line interaction. If isTextMode would return false, no conversion is done.

Returns: true if the conversion was possible

argc	Number of blocks
argv	An array of integers, giving the length of each block

data	Start of the block of data
len	Length of the block of data
