wasRecentlyClosed
public boolean wasRecentlyClosed(long inboundID) Was this conn recently closed?- Since:
- 0.9.12
-
setSoTimeout
public void setSoTimeout(long x) Set the socket accept() timeout.- Parameters:
x
-
-
getSoTimeout
public long getSoTimeout()Get the socket accept() timeout.- Returns:
- accept timeout in ms.
-
setAllowIncomingConnections
public void setAllowIncomingConnections(boolean allow) -
updateOptions
public void updateOptions() -
getAllowIncomingConnections
public boolean getAllowIncomingConnections()- Returns:
- if we should accept connections
-
receiveConnection
Create a new connection based on the SYN packet we received.- Parameters:
synPacket
- SYN packet to process- Returns:
- created Connection with the packet's data already delivered to it, or null if the syn's streamId was already taken, or if the connection was rejected
-
receivePing
Process a ping by checking for throttling, etc., then sending a pong.- Parameters:
con
- null if unknownping
- Ping packet to process, must have From and Sig fields, with signature already verified, only if answerPings() returned true- Returns:
- true if we sent a pong
- Since:
- 0.9.12 from PacketHandler.receivePing()
-
connect
Build a new connection to the given peer. This blocks if there is no connection delay, otherwise it returns immediately.- Parameters:
peer
- Destination to contact, non-nullopts
- Connection's optionssession
- generally the session from the constructor, but could be a subsession- Returns:
- new connection, or null if we have exceeded our limit

answerPings
public boolean answerPings()do we respond to pings that aren't on an existing connection? -
disconnectAllHard
public void disconnectAllHard()Something b0rked hard, so kill all of our connections without mercy. Don't bother sending close packets. This will not close the ServerSocket. This will not kill the timer threads. CAN continue to use the manager. -
shutdown
public void shutdown()Kill all connections and the timers. Don't bother sending close packets. As of 0.9.17, this will close the ServerSocket, killing one thread in accept(). CANNOT continue to use the manager or restart.- Since:
- 0.9.7

con
- Connection to drop.
-
listConnections
return a set of Connection objects- Returns:
- set of Connection objects
