public class Router_LSA

extends ProtocolMessage

This class implements an OSPF Router Link State Advertisement. The following from RFC 2328 was not included: 1.) TOS 2.) TOS Metric

Field Summary

boolean	isAreaBorderRouter Indicates the B-bit in an Router-LSA (Border)
boolean	isASBoundaryRouter Indicates the E-bit in an Router-LSA (External)
boolean	isVirtLinkEndPoint Indicates the V-bit in an Router-LSA (Virtual)
java.util.Vector	links A Vector collecting all link descriptions (LinkInfo) belonging to this Router_LSA.

Constructor Summary

Router_LSA(boolean v, boolean e, boolean b)

Method Summary

void	addLink(LinkInfo link) add a new link info to this router LSA.
int	bytecount() Return the total size (in bytes) of this Router_LSA body.
void	carryPayload(ProtocolMessage payload) Append a ProtocolMessage to this ProtocolMessage.
ProtocolMessage	copy() Return an exact copy of this data structure.
boolean	equals(java.lang.Object test) Take a Router_LSA an compare it to this Router_LSA.
int	getNumOfLinks() Return the Number of link informations stored in this Router_LSA.
int	header_bytecount() Return the size (in bytes) of this header only, don't include a payload.

Constructor Detail

Router_LSA

public Router_LSA(boolean v,
                  boolean e,
                  boolean b)

Method Detail

carryPayload

public void carryPayload(ProtocolMessage payload)

Description copied from class: ProtocolMessage

Append a ProtocolMessage to this ProtocolMessage.

Overrides:

carryPayload in class ProtocolMessage

addLink

public void addLink(LinkInfo link)

add a new link info to this router LSA.

getNumOfLinks

public int getNumOfLinks()

Return the Number of link informations stored in this Router_LSA.

bytecount

public int bytecount()

Return the total size (in bytes) of this Router_LSA body. All and only fields specified in RFC 2328 are included in calculation!!!

Overrides:

bytecount in class ProtocolMessage

header_bytecount

public int header_bytecount()

Return the size (in bytes) of this header only, don't include a payload. Router_LSA Classes don't have payload.

Overrides:

header_bytecount in class ProtocolMessage

copy

public ProtocolMessage copy()

Return an exact copy of this data structure. This method is used indirectly by the Neighbor Data Structure to send a copy of a Router LSA to its associated Neighbor.

Overrides:

copy in class ProtocolMessage

equals

public boolean equals(java.lang.Object test)

Take a Router_LSA an compare it to this Router_LSA. If there is no difference between them return true else false.

Overrides:

equals in class java.lang.Object

Parameters:

test - Object referencing a Router_LSA to compare.

Returns:

boolean value indicating whether the contents of the Router_LSAs are equal.
