java.lang.Object

com.h3c.sdn.misc.net.LinkInfoDTO

All Implemented Interfaces:

LinkInfo, Serializable

public class LinkInfoDTO
extends Object
implements LinkInfo, Serializable

Provides an implementation of LinkInfo, representing the link status and the time of discovery of a layer 2 link in the network.

Instances of this class are mutable and hence not thread-safe.

Constructor Detail

LinkInfoDTO

public LinkInfoDTO(long unicastDiscoveryTime,
           long multicastDiscoveryTime,
           Set<PortState> srcPortState,
           Set<PortState> dstPortState)

Creates a DTO representing the link status and the time of discovery of a layer 2 link in the network.

Parameters:

unicastDiscoveryTime - the time at which the direct link was discovered

multicastDiscoveryTime - the time at which the direct link was discovered by means other than standard LLDP packet

srcPortState - the state of the source port of the associated link

dstPortState - the state of the destination port of the associated link

Throws:

NullPointerException - if srcPortState or dstPortState is null

Method Detail

unicastDiscoveryTime

public long unicastDiscoveryTime()

Description copied from interface: LinkInfo

Returns the time at which the direct link was discovered.

The term unicast may be slightly misleading here; the standard LLDP destination MAC address that is currently used is a multicast address, however since this address is specified in the standard, we expect all switches to absorb the standard packet, thus making the standard LLDP packet describe only one link.

Specified by:

unicastDiscoveryTime in interface LinkInfo

Returns:

the time of discovery of the associated link

multicastDiscoveryTime

public long multicastDiscoveryTime()

Description copied from interface: LinkInfo

Returns the time at which the direct link was discovered by means other than standard LLDP packet. For example, from a BDDP packet.

Specified by:

multicastDiscoveryTime in interface LinkInfo

Returns:

the time of discovery of the associated link

srcPortState

public Set<PortState> srcPortState()

Description copied from interface: LinkInfo

Returns the state of the source port of the associated link.

Specified by:

srcPortState in interface LinkInfo

Returns:

the state of the source port

dstPortState

public Set<PortState> dstPortState()

Description copied from interface: LinkInfo

Returns the state of the destination port of the associated link.

Specified by:

dstPortState in interface LinkInfo

Returns:

the state of the destination port

type

public Link.Type type()

Description copied from interface: LinkInfo

Returns the type of the associated link, i.e. a direct link, multi-hop link or a tunnel.

Specified by:

type in interface LinkInfo

Returns:

the type of the associated link

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

toKeyString

public String toKeyString()

valueOf

public static LinkInfoDTO valueOf(String str)

updateUnicastDiscoveryTime

public void updateUnicastDiscoveryTime(long unicastDiscoveryTime)

Description copied from interface: LinkInfo

Updates the time at which the direct link was discovered with the specified value.

Specified by:

updateUnicastDiscoveryTime in interface LinkInfo

Parameters:

unicastDiscoveryTime - the time of discovery to set

updateMulticastDiscoveryTime

public void updateMulticastDiscoveryTime(long multicastDiscoveryTime)

Description copied from interface: LinkInfo

Updates the time at which the direct link was discovered by means other than standard LLDP packet, with the specified value.

Specified by:

updateMulticastDiscoveryTime in interface LinkInfo

Parameters:

multicastDiscoveryTime - the time of discovery to set

updateSrcPortState

public void updateSrcPortState(Set<PortState> srcPortState)

Description copied from interface: LinkInfo

Updates the state of the source port of the associated link.

Specified by:

updateSrcPortState in interface LinkInfo

Parameters:

srcPortState - the state of the source port

updateDstPortState

public void updateDstPortState(Set<PortState> dstPortState)

Description copied from interface: LinkInfo

Updates the state of the destination port of the associated link.

Specified by:

updateDstPortState in interface LinkInfo

Parameters:

dstPortState - the state of the destination port
