SessionAddress

public class SessionAddress extends Object implements Serializable
Class to encapsulate a pair of internet address and a pair of ports for use in RTPSM methods.

Fields Summary
private InetAddress
m_dataAddress
private InetAddress
m_controlAddress
private int
m_dataPort
private int
m_controlPort
private int
ttl
public static final int
ANY_PORT
Constructors Summary
public SessionAddress(InetAddress dataAddress, int dataPort)
Constructor to create an SessionAddress given the data internet address and data port.

param
dataAddress The data address.

param
dataPort The data port. If this value is passed as the constant ANY_PORT, the object will not represent a specific data port. 

    
                                                                
     
	  
			                  						      
	m_dataAddress = dataAddress;
	m_controlAddress = dataAddress;
	m_dataPort = dataPort;
	m_controlPort = dataPort + 1;
public SessionAddress(InetAddress dataAddress, int dataPort, int timeToLive)
Constructor to create an SessionAddress given the data internet address and data port.

param
dataAddress The data address.

param
dataPort The data port. If this value is passed as the constant ANY_PORT, the object will not represent a specific data port.

param
timeToLive The time-to-live parameter for multicast sessions 

        						     
	m_dataAddress = dataAddress;
	m_controlAddress = dataAddress;
	m_dataPort = dataPort;
	m_controlPort = dataPort + 1;
	
	ttl= timeToLive;
public SessionAddress(InetAddress dataAddress, int dataPort, InetAddress controlAddress, int controlPort)
Constructor to create an SessionAddress given both internet address and ports.

param
dataAddress The data address.

param
dataPort The data port. If this value is passed as the constant ANY_PORT, the object will not represent a specific data port.

param
controlAddress The control address.

param
controlPort The control port. If this value is passed as the constant ANY_PORT, the object will not represent a specific control port. 

	m_dataAddress = dataAddress;
	m_controlAddress = controlAddress;
	m_dataPort = dataPort;
	m_controlPort = controlPort;
public SessionAddress()
Constructor to create an "empty" RTPSesionAddress. Equivalent to calling SessionAddress(null, ANY_PORT, null, ANY_PORT). 

	this(null, ANY_PORT, null, ANY_PORT);
