Field Detail

PORT_MIN_VALUE

public static final int PORT_MIN_VALUE

Constant Field Values

PORT_MAX_VALUE

public static final int PORT_MAX_VALUE

See Also:

Constant Field Values

m_strHostname

private java.lang.String m_strHostname

This is the host of this interface (hostname or IP).

m_iInetPort

private int m_iInetPort

This is the representation of the port of the ListenerInterface.

m_iProtocolType

private int m_iProtocolType

This describes the protocol type.

m_bUseInterface

private boolean m_bUseInterface

This describes, whether we can reach this interface or not. If we can't get a connection to this interface, we set it to false and so there are no more connection trys. The interface still remains in the database because others may get a connection to this interface (causes can be firewalls, another network, ...). This is only meaningful for non-local (remote) interfaces.
