Class TcpUdpPortPair

java.lang.Object

com.h3c.util.cache.CacheableDataType

com.h3c.util.ip.TcpUdpPortPair

All Implemented Interfaces:

Serializable, Comparable<TcpUdpPortPair>

public final class TcpUdpPortPair
extends CacheableDataType
implements Comparable<TcpUdpPortPair>

Represents a pair of ports defined by a source IpAddress and TcpUdpPort and a destination IpAddress and TcpUdpPort.

All constructors for this class are private. Creating instances of TcpUdpPortPair is done via the static valueOf(com.h3c.util.ip.IpAddress, com.h3c.util.ip.TcpUdpPort, com.h3c.util.ip.IpAddress, com.h3c.util.ip.TcpUdpPort) methods on the class.

Instances of this class are immutable, making them inherently thread-safe.

This class overrides equals(java.lang.Object) and hashCode() so that instances play nicely with the Collection classes.

This class implements the Comparable interface to ensure that a sorted list of pairs is presented in an intuitive order.

Methods

Modifier and Type	Method and Description
int	compareTo(TcpUdpPortPair o) This implementation of the Comparable interface sorts by source IP/port first, then destination IP/port.
boolean	equals(Object o)
IpAddress	getDestinationIp() Returns the IP address of the destination.
TcpUdpPort	getDestinationPort() Returns the port of the destination.
IpAddress	getSourceIp() Returns the IP address of the source.
TcpUdpPort	getSourcePort() Returns the port of the source.
int	hashCode()
String	toShortString() Returns the string representation of this port pair, without including the well-known names of the ports.
String	toString() Returns the string representation of this port pair, including the well-known names of the ports.
static TcpUdpPortPair	valueOf(IpAddress sourceIp, TcpUdpPort sourcePort, IpAddress destIp, TcpUdpPort destPort) Returns a TcpUdpPortPair object that represents the source and destination ports specified by the given IP addresses and TCP/UDP ports.

Returns:

a number indicating relative ordering

valueOf

public static TcpUdpPortPair valueOf(IpAddress sourceIp,
                     TcpUdpPort sourcePort,
                     IpAddress destIp,
                     TcpUdpPort destPort)

Returns a TcpUdpPortPair object that represents the source and destination ports specified by the given IP addresses and TCP/UDP ports.

Parameters:

sourceIp - the IP address of the source

sourcePort - the TCP/UDP port of the source

destIp - the IP address of the destination

destPort - the TCP/UDP port of the destination

Returns:

the source / destination port pair

Throws:

NullPointerException - if any of the parameters are null

IllegalArgumentException - if the port protocols don't match
