Detailed Description

Auxiliary data structure for hostname and port number.

Definition at line 33 of file JHostname.hh.

Constructor & Destructor Documentation

JNET::JHostname::JHostname ( )

inline

Default constructor.

Definition at line 45 of file JHostname.hh.

                :
      hostname(""),
      port(-1)
    {}

JNET::JHostname::JHostname ( const std::string &  buffer )

inline

Constructor.

The argument correponds to the hostname and an optional port number of the server. The syntax is hostname[:port]. The default port number is DISPATCH_PORT. If the complete buffer corresponds to an integer value, it is interpreted as the port number.

Parameters

buffer

host name and optional port number

Definition at line 61 of file JHostname.hh.

    {
      set(buffer);
    }

JNET::JHostname::JHostname ( const std::string &  hostname, const int  port  )

inline

Constructor.

Parameters

hostname	hostname
port	port number

Definition at line 73 of file JHostname.hh.

    {
      this->hostname = hostname;
      this->port     = port;
    }

Member Function Documentation

bool JNET::JHostname::equals ( const JHostname &  hostname ) const

inline

Equal method.

Parameters

hostname

host name and port

Returns

true if this host name and port is equal to given host name and port; else false

Definition at line 87 of file JHostname.hh.

    {
      return (this->hostname == hostname.hostname  &&
              this->port     == hostname.port);
    }

void JNET::JHostname::set ( const std::string &  buffer )

inline

Set hostname and port number.

The argument correponds to the hostname and an optional port number of the server.
The syntax is hostname[:port]. The default port number is DISPATCH_PORT.
If the complete buffer corresponds to an integer value, it is interpreted as the port number.

Parameters

buffer

host name and optional port number

Definition at line 104 of file JHostname.hh.

    {
      using namespace std;

      const string::size_type pos = buffer.find(SEPARATOR);

      if (pos != string::npos) {

        this->hostname = buffer.substr(0, pos);

        istringstream(buffer.substr(pos + 1)) >> this->port;

      } else {

        bool is_number = true;

        for (string::const_iterator i = buffer.begin(); is_number && i != buffer.end(); ++i) {
          is_number &= isdigit(*i);
        }

        if (is_number) {

          this->hostname = "";

          istringstream(buffer) >> this->port;

        } else {

          this->hostname = buffer;
          this->port     = DISPATCH_PORT;
        }
      }
    }
