Constructor & Destructor Documentation

forest::Repeater::~Repeater ( )

Destructor for Repeater.

Definition at line 21 of file Repeater.cpp.

pair< int, int > forest::Repeater::deleteMatch ( int64_t seqNum)

Match a reply to a saved request and update.

Parameters

seqNum is the sequence number assigned to the reply

Definition at line 43 of file Repeater.cpp.

Here is the caller graph for this function:

pair< int, int > forest::Repeater::overdue ( int64_t now)

Check for an overdue packet.

Parameters

now	is the current time

Returns: a pair (cx, idx) where cx is the packet index for an overdue packet that was saved earlier; idx is the index under which the packet was saved; if the packet has been overdue more than the allowed number of times (3), the value of cx is negated to signal this condition and the save copy is removed

Definition at line 60 of file Repeater.cpp.

Here is the caller graph for this function:

Save a copy of an outgoing request packet.

Parameters

cx	is a copy of some outgoing request packet
seqNum	is the sequence number assigned to the packet
now	is the current time
idx	is an optional index that identifies the saved copy; if zero, an index is assigned automatically

Returns: the index associated with the saved copy or 0 if a specified index is not available
