Constructor Detail

InstanceConnectionInfo

public InstanceConnectionInfo(InetAddress inetAddress,
                      int ipcPort,
                      int dataPort)

Constructs a new instance connection info object. The constructor will attempt to retrieve the instance's hostname and domain name through the operating system's lookup mechanisms.

Parameters:

inetAddress - the network address the instance's task manager binds its sockets to

ipcPort - the port instance's task manager runs its IPC service on

dataPort - the port instance's task manager expects to receive transfer envelopes on

InstanceConnectionInfo

public InstanceConnectionInfo(InetAddress inetAddress,
                      String hostName,
                      String domainName,
                      int ipcPort,
                      int dataPort)

Constructs a new instance connection info object.

Parameters:

inetAddress - the network address the instance's task manager binds its sockets to

hostName - the host name of the instance

domainName - the domain name of the instance

ipcPort - the port instance's task manager runs its IPC service on

dataPort - the port instance's task manager expects to receive transfer envelopes on.

InstanceConnectionInfo

public InstanceConnectionInfo()

Constructs an empty InstanceConnectionInfo object.

Method Detail

ipcPort

public int ipcPort()

Returns the port instance's task manager runs its IPC service on.

Returns:

the port instance's task manager runs its IPC service on

dataPort

public int dataPort()

Returns the port instance's task manager expects to receive transfer envelopes on.

Returns:
