Detailed Description

The module and factory to drive the transmission of tracker events via the network.

It grabs the events from various NetworkSink nodes and distributes them to specified multicast groups or unicast datagrams.

Member Function Documentation

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

closes the module and closes any communication sockets.

Reimplemented from ot::Module.

Definition at line 304 of file NetworkSinkModule.cxx.

References multicasts, and unicasts.

void ot::NetworkSinkModule::convertFloatsHToNl ( std::vector< float > &  floats,
float *  result,
int  num 
) [protected]

converts floats to network byte order.

floats vector of floats to convert
result pointer where to store the result ( can be floats )
num number of floats to convert

Definition at line 464 of file NetworkSinkModule.cxx.

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

This method is called to construct a new Node.

It compares name to the NetworkSink element name, and if it matches creates a new NetworkSink node.

name reference to string containing element name refenrence to StringMap containing attribute values
pointer to new Node or NULL. The new Node must be allocated with new !

Implements ot::NodeFactory.

void ot::NetworkSinkModule::init ( StringTable attributes,
ConfigNode localTree 
) [virtual]

initializes the tracker module.

attributes StringMap of elements attribute values. Should be possibly , but is not for convenience.
localTree pointer to root of configuration nodes tree

Reimplemented from ot::Module.

Definition at line 179 of file NetworkSinkModule.cxx.

References ot::StringTable::containsKey(), ot::StringTable::get(), ot::Module::init(), and serverName.

void ot::NetworkSinkModule::pullEvent (  )  [virtual]

pulls event information out of the tracker tree.

It checks the modified member on each NetworkSink node and if a new value is stored it inserts it into the apropriate network data buffer. Then it sends any non-empty data buffers to the network.

Reimplemented from ot::Module.

Definition at line 321 of file NetworkSinkModule.cxx.

References LOG_ACE_ERROR(), multicasts, nodes, and unicasts.

void ot::NetworkSinkModule::runUnicastTransceiver ( void *  data  )  [static, protected]

Runs the unicast transceiver thread.

The function reads from and writes to the network and parses network packages.

data the unicast receiver

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

This method is called after initialisation is finished and before the main loop is started.

It opens the sockets needed for communication.

Reimplemented from ot::Module.
