Member Function Documentation

◆ Clear()

void qrtplib::RTPCollisionList::Clear ( )

Clears the list of addresses.

Here is the caller graph for this function:

◆ HasAddress()

bool qrtplib::RTPCollisionList::HasAddress ( const RTPAddress * addr ) const

Returns true} if the address addr appears in the list.

 }

◆ Timeout()

void qrtplib::RTPCollisionList::Timeout	(	const RTPTime &	currenttime,
		const RTPTime &	timeoutdelay
	)

Assuming that the current time is given by currenttime, this function times out entries which haven't been updated in the previous time interval specified by timeoutdelay.

Here is the caller graph for this function:

◆ UpdateAddress()

int qrtplib::RTPCollisionList::UpdateAddress	(	const RTPAddress *	addr,
		const RTPTime &	receivetime,
		bool *	created
	)

Updates the entry for address addr to indicate that a collision was detected at time receivetime. Updates the entry for address addr to indicate that a collision was detected at time receivetime. If the entry did not exist yet, the flag created is set to true, otherwise it is set to false.
