Member Function Documentation

bool ns3::aodv::RerrHeader::AddUnDestination	(	Ipv4Address	dst,
		uint32_t	seqNo
	)

Add unreachable node address and its sequence number in RERR header

Returns:: false if we already added maximum possible number of unreachable destinations

uint32_t ns3::aodv::RerrHeader::Deserialize ( Buffer::Iterator start ) [virtual]

Parameters:

start

an iterator which points to where the header should written.

Returns:: the number of bytes read.

This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.

Implements ns3::Header.

TypeId ns3::aodv::RerrHeader::GetInstanceTypeId ( ) const [virtual]

Returns:: the TypeId associated to the most-derived type of this instance.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Implements ns3::ObjectBase.

uint32_t ns3::aodv::RerrHeader::GetSerializedSize ( ) const [virtual]

Returns:: the expected size of the header.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. This method should return the number of bytes which are needed to store the full header data by Serialize.

Implements ns3::Header.

static TypeId ns3::aodv::RerrHeader::GetTypeId ( void ) [static]

This method returns the TypeId associated to ns3::Header.

No Attributes defined for this type.
No TraceSources defined for this type.

Reimplemented from ns3::Header.

void ns3::aodv::RerrHeader::Print ( std::ostream & os ) const [virtual]

Parameters:

os

output stream This method is used by Packet::Print to print the content of a trailer as ascii data to a c++ output stream. Although the trailer is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5

Implements ns3::Header.

bool ns3::aodv::RerrHeader::RemoveUnDestination ( std::pair< Ipv4Address, uint32_t > & un )

Delete pair (address + sequence number) from REER header, if the number of unreachable destinations > 0

Returns:: true on success

void ns3::aodv::RerrHeader::Serialize ( Buffer::Iterator start ) const [virtual]

Parameters:

start

an iterator which points to where the header should be written.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. The data written is expected to match bit-for-bit the representation of this header in a real network.

Implements ns3::Header.
