◆ read()

bool Sound::read ( yarp::os::ConnectionReader & reader )

overridevirtual

Read this object from a network connection.

Override this for your particular class.

Parameters

reader an interface to the network connection for reading

Returns: true iff the object is successfully read

Implements yarp::os::Portable.

Definition at line 231 of file Sound.cpp.

◆ replaceChannel()

bool Sound::replaceChannel	(	size_t	id,
		Sound	channel
	)

Replace a single channel of our current sound with a given sound constituted by a single channel The two sounds must have the same number of samples.

Parameters

id	the channel of our sound that we want to replace
channel	the single-channel sound that we want to put in our sound

Definition at line 317 of file Sound.cpp.

◆ write()

bool Sound::write ( yarp::os::ConnectionWriter & writer ) const

overridevirtual

Write this object to a network connection.

Override this for your particular class. Be aware that depending on the nature of the connections a port has, and what protocol they use, and how efficient the YARP implementation is, this method may be called once, twice, or many times, as the result of a single call to Port::write

Parameters

writer an interface to the network connection for writing

Returns: true iff the object is successfully written

Implements yarp::os::Portable.
