Detailed Description

The module and factory to drive the reception of network state updates. It builds NetworkSource nodes that insert data from the network into the tracker tree. It uses the Flexible Network Protocol from the studierstube. It uses its a thread per multicast group to receive data.

Member Function Documentation

void ot::OldOTNetworkSourceModule::close (   )  [virtual]

closes the module and closes any communication sockets and stops thread. Reimplemented from ot::Module.

void ot::OldOTNetworkSourceModule::convertFloatsNToHl (  float *  floats, float *  result, int  num )  [static, protected]

Converts num floats from network byte order. Parameters: floats  pointer to source data result  pointer to result array num  number of floats to convert

Node * ot::OldOTNetworkSourceModule::createNode (  const std::string &  name, StringTable &  attributes )  [virtual]

This method is called to construct a new Node. It compares name to the NetworkSource element name, and if it matches creates a new NetworkSource node. Parameters: name  reference to string containing element name refenrence to StringTable containing attribute values Returns: pointer to new Node or NULL. The new Node must be allocated with new ! Implements ot::NodeFactory.

void ot::OldOTNetworkSourceModule::pushEvent (   )  [virtual]

pushes state information into the tree. It checks whether there is new data for any NetworkSource node, copies it into the nodes and calls push on them. Reimplemented from ot::Module.

void ot::OldOTNetworkSourceModule::run (  void *  data  )  [static, protected]

the work method for the module thread. This is executed by the new module thread. In this class it does nothing but subclasses should override it to add their implementation.

void ot::OldOTNetworkSourceModule::start (   )  [virtual]

opens the sockets needed for communication and starts the receive thread. It is called after initialisation is done. Reimplemented from ot::Module.
