Constructor & Destructor Documentation

ArLMS2xxPacketReceiver::ArLMS2xxPacketReceiver (  unsigned char  receivingAddress = 0, bool  allocatePackets = false, bool  useBase0Address = false )

Constructor without an already assigned device connection. Parameters: allocatePackets  whether to allocate memory for the packets before returning them (true) or to just return a pointer to an internal packet (false)... most everything should use false as this will help prevent many memory leaks or corruptions

ArLMS2xxPacketReceiver::ArLMS2xxPacketReceiver (  ArDeviceConnection *  deviceConnection, unsigned char  receivingAddress = 0, bool  allocatePackets = false, bool  useBase0Address = false )

Constructor with assignment of a device connection. Parameters: deviceConnection  the connection which the receiver will use allocatePackets  whether to allocate memory for the packets before returning them (true) or to just return a pointer to an internal packet (false)... most everything should use false as this will help prevent many memory leaks or corruptions

Member Function Documentation

ArLMS2xxPacket * ArLMS2xxPacketReceiver::receivePacket (  unsigned int  msWait = 0  )

Receives a packet from the robot if there is one available. Parameters: msWait  how long to block for the start of a packet, nonblocking if 0 Returns: NULL if there are no packets in alloted time, otherwise a pointer to the packet received, if allocatePackets is true than the place that called this function owns the packet and should delete the packet when done... if allocatePackets is false then nothing must store a pointer to this packet, the packet must be used and done with by the time this method is called again
