Member Function Documentation

uint32_t ns3::ArpHeader::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::ArpHeader::GetInstanceTypeId ( void ) 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.

Here is the call graph for this function:

uint32_t ns3::ArpHeader::GetSerializedSize ( void ) 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.

void ns3::ArpHeader::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
