/**
* The DomainParticipant object plays several roles:
* - It acts as a container for all other Entity objects
* - It acts as factory for the Publisher, Subscriber, Topic and MultiTopic Entity objects.
* - It represents the participation of the application on a communication plane that
* isolates applications running on the same set of physical computers from each other.
* A domain establishes a �virtual network� linking all applications that share the
* same domainId9 and isolating them from applications running on different domains.
* In this way, several independent distributed applications can coexist in the same
* physical network without interfering, or even being aware of each other.
* - It provides administration services in the domain, offering operations that allow the
* application to �ignore� locally any information about a given participant
