const void* phy::header< prism::header >::decapsulate | ( | size_t | caplen, | |
bool | swapped | |||

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()
.

) | [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()
.

) | [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()

Get the PHY header length.
Never override this method. Define len_impl()
in subclasses instead.
time_type phy::header< prism::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.

bool | swapped | |||

Set the PHY header's timing information.
