Detailed Description

template<class T>
class dueca::EventWriter< T >

This is a facilitator for writing event data.

By creating a "EventWriter", an event data object is created. When at the end of scope the EventWriter is destroyed, the data object is sent over the channel.

Template Parameters

Data	type of the event channel, normally a dco (DUECA Comunication Object), generated from a .dco file.

An example, suppose you have created an EventChannelWriteToken for a channel with MyData objects:

if (have_to_write_event) {
 
  // create the writer
  EventWriter<MyData> w(my_event_write_token, ts);
 
  // put the proper data in
  w.data().a = some_value;
  w.data().b = some_other_value;
  // etc. Note that you get cryptic error messages if you forget
  // that data() is a function, and type "w.data.a"
 
  // Another note: unless you specify defaults for the data in
  // your MyData.dco file, the stuff that is in the MyData event
  // is initially undefined. So do not forget to assign values to
  // all members of your event.
 
} // <-- This closing bracket ends the "scope", in which
  // EventWriter<MyData> w was created. That means that at this
  // point the EventWriter<MyData> destructor is called. The
  // destructor actually sends the data over the channel.
