typedef rtap::header rtap::header::exact_type |
Exact type for this template instanciation.
Reimplemented from phy::header< rtap::header >.
const void * rtap::header::first_field | ( | size_t | caplen | ) | const [inline] |
Get the Radiotap header's first field address (or 0 if not available).
Const version.
void * rtap::header::first_field | ( | size_t | caplen | ) | [inline] |
Get the Radiotap header's first field address (or 0 if not available).
Non-const version.
uint64_t rtap::header::tsft_get | ( | size_t | caplen | ) | const [inline] |
Get the Radiotap header TSFT field, or throw std::invalid_argument
.
size_t phy::header< rtap::header >::len | ( | size_t | caplen, | |
bool | swapped | |||
) | const [inherited] |
Get the PHY header length.
Never override this method. Define len_impl()
in subclasses instead.
const void* phy::header< rtap::header >::decapsulate | ( | size_t | caplen, | |
bool | swapped | |||
) | const [inherited] |
Get the embedded IEEE 802.11 frame.
Return 0 if len() > caplen.
This method relies on len()
. You should not need to override it if your subclasses define a proper len_impl()
.
time_type phy::header< rtap::header >::time_get | ( | bool | swapped | ) | const [inherited] |
Extract timing information from the PHY header.
Never override this method. Define time_get_impl()
in subclasses instead.
void phy::header< rtap::header >::time_set | ( | const time_type & | time, | |
bool | swapped | |||
) | [inherited] |
Set the PHY header's timing information.
Never override this method. Define time_set_impl()
in subclasses instead.
static bool phy::header< rtap::header >::eq_80211 | ( | const pcapxx::frame_descriptor< D1 > & | lhs, | |
const pcapxx::frame_descriptor< D2 > & | rhs, | |||
tool::endian::endianness | phy_end = tool::endian::guess | |||
) | [inline, static, inherited] |
Compare the IEEE 802.11 bytes beyond the PHY header.
Return whether the two IEEE 802.11 frames embedded inside the PHY headers are equals. This function does not compare the PHY headers.
In case there is not enough bytes to decide whether frames are equal (caplen < sizeof prism::header), consider they are not. This is a conservative approach: when merging two traces, this will lead to both frames having their entry in the merged trace.
This method relies on decapsulate()
. You should not need to override it if your subclasses define a proper decapsulate_impl()
.
static bool phy::header< rtap::header >::eq_time_and_80211 | ( | const pcapxx::frame_descriptor< D1 > & | lhs, | |
const pcapxx::frame_descriptor< D2 > & | rhs, | |||
tool::endian::endianness | phy_end = tool::endian::guess , |
|||
unsigned | precision = phy::eq_time_default_precision | |||
) | [inline, static, inherited] |
Compare the IEEE 802.11 bytes beyond PHY headers, but also check timestamps.
Return whether the two IEEE 802.11 frames embedded inside the PHY headers are equals. Also compare the timestamps of PHY headers if available (or the PCAP timestamps else). When the time difference between each header's field is less than precision
, then consider the field equals.
In case there is not enough bytes to decide whether frames are equal (caplen < sizeof prism::header), consider they are not. This is a conservative approach: when merging two traces, this will lead to both frames having their entry in the merged trace.
This method relies on eq_time()
. You should not need to override it if your subclasses define a proper eq_time()
.
const exact_type& tool::static_base< rtap::header >::exact | ( | ) | const [inherited] |
Safely downcast to the exact type as a const reference.
exact_type& tool::static_base< rtap::header >::exact | ( | ) | [inherited] |
Safely downcast to the exact type as a non-const reference.
const exact_type* tool::static_base< rtap::header >::exact_ptr | ( | ) | const [inherited] |
Safely downcast to the exact type as a const pointer.
exact_type* tool::static_base< rtap::header >::exact_ptr | ( | ) | [inherited] |
Safely downcast to the exact type as a non-const pointer.
uint8_t rtap::header::it_version |
Must be zero.
uint8_t rtap::header::it_pad |
Padding; undefined.
uint16_t rtap::header::it_len |
Header's entire length.
uint32_t rtap::header::it_present |
Available fields.
