Detailed Description

Represents a unique identifier for each Fountain node in the system.

handles Fountain node identifcation in the form of hostname_listenport where hostname is the hostname truncated to the first period and listenport is the listening socket number that the Fountain node is using to accept new connections.

Constructor & Destructor Documentation

NodeID::NodeID (  const std::string &  ID  )

Constructor. Exceptions: FountainException  if the ID parameter could not be parsed Parameters: ID  The identifier string of a FountainNode Definition at line 53 of file NodeID.cpp. References ENFORCE, std::basic_string< _CharT, _Traits, _Alloc >::find_first_of(), hostname_, ID_, listenPort_, std::basic_string< _CharT, _Traits, _Alloc >::size(), and std::basic_string< _CharT, _Traits, _Alloc >::substr(). Here is the call graph for this function:
