Detailed Description

template<typename T>
class yarp::os::TypedReaderCallback< T >

A callback for typed data from a port.

If you want to get your data while leaving the port free to read more in the background, you can create a callback that implements this interface, and tell the port about it using BufferedPort::useCallback(callback) or PortReaderBuffer::useCallback(callback)

Examples

port_power/ex0302_buffered_ext_callback.cpp, and port_power/ex0403_bufferedport_callback_reply.cpp.

onRead() [2/2]

template<typename T >

void yarp::os::TypedReaderCallback< T >::onRead ( T &  datum, const yarp::os::TypedReader< T > &  reader  )

virtual

Callback method.

Passes along source of callback. By default, this calls the version of onRead that just takes a datum.

Parameters

datum	data read from a port
reader	the original port (or delegate object)
