Member Function Documentation

uint32_t ns3::LlcSnapHeader::Deserialize ( Buffer::Iterator  start)
virtual
Parameters
startan 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.

Definition at line 92 of file llc-snap-header.cc.

References GetSerializedSize(), m_etherType, ns3::Buffer::Iterator::Next(), NS_LOG_FUNCTION, ns3::Buffer::Iterator::ReadNtohU16(), and visualizer.core::start().

+ Here is the call graph for this function:

TypeId ns3::LlcSnapHeader::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.

Definition at line 68 of file llc-snap-header.cc.

References GetTypeId().

+ Here is the call graph for this function:

uint32_t ns3::LlcSnapHeader::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.

Implements ns3::Header.

void ns3::LlcSnapHeader::Print ( std::ostream &  os) const
virtual
Parameters
osoutput 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

void ns3::LlcSnapHeader::Serialize ( Buffer::Iterator  start) const
virtual
Parameters
startan 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.
