uint32_t ns3::Icmpv4Header::Deserialize | ( | Buffer::Iterator | start | ) | [virtual] |
start | an iterator which points to where the header should written. |
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::Icmpv4Header::GetInstanceTypeId | ( | void | ) | const [virtual] |
This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

uint32_t ns3::Icmpv4Header::GetSerializedSize | ( | void | ) | const [virtual] |
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.

void ns3::Icmpv4Header::Print | ( | std::ostream & | os | ) | const [virtual] |
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.
void ns3::Icmpv4Header::Serialize | ( | Buffer::Iterator | start | ) | const [virtual] |
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.
