Member Function Documentation

◆ Deserialize()

uint32_t ns3::AmpduSubframeHeader::Deserialize ( Buffer::Iterator start )

overridevirtual

Parameters

start an iterator which points to where the header should read from.

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.

Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

Implements ns3::Header.

◆ GetEof()

Returns: the EOF field

◆ GetInstanceTypeId()

TypeId ns3::AmpduSubframeHeader::GetInstanceTypeId ( void ) const

overridevirtual

Get the most derived TypeId for this Object.

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

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

Implements ns3::ObjectBase.

◆ GetLength()

uint16_t ns3::AmpduSubframeHeader::GetLength ( void ) const

Returns: the length field in bytes

◆ GetSerializedSize()

uint32_t ns3::AmpduSubframeHeader::GetSerializedSize ( void ) const

overridevirtual

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.

Definition at line 57 of file ampdu-subframe-header.cc.

◆ GetTypeId()

TypeId ns3::AmpduSubframeHeader::GetTypeId ( void )

Get the type ID.

Returns: the object TypeId

◆ IsSignatureValid()

bool ns3::AmpduSubframeHeader::IsSignatureValid ( void ) const

Return whether the pattern stored in the delimiter signature field is correct, i.e.

corresponds to the unique pattern 0x4E.

Returns: true if the signature is valid, false otherwise

Definition at line 114 of file ampdu-subframe-header.cc.

References m_signature.

◆ Print()

void ns3::AmpduSubframeHeader::Print ( std::ostream & os ) const

overridevirtual

Parameters

os output stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header 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

◆ Serialize()

void ns3::AmpduSubframeHeader::Serialize ( Buffer::Iterator start ) const

overridevirtual

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.
