Method Detail

setKillVMOnEnd

public void setKillVMOnEnd(boolean shouldDie)
Configure the router to kill the JVM when the router shuts down, as well as whether to explicitly halt the JVM during the hard fail process.

getRouterInfo

public RouterInfo getRouterInfo()

setRouterInfo

public void setRouterInfo(RouterInfo info)

getHigherVersionSeen

public boolean getHigherVersionSeen()
True if the router has tried to communicate with another router who is running a higher incompatible protocol version.


setHigherVersionSeen

public void setHigherVersionSeen(boolean seen)

getWhenStarted

public long getWhenStarted()

getUptime

public long getUptime()
wall clock uptime


getContext

public RouterContext getContext()

runRouter

void runRouter()

readConfig

public void readConfig()

isAlive

public boolean isAlive()

rebuildRouterInfo

public void rebuildRouterInfo()
Rebuild and republish our routerInfo since something significant has changed.


rebuildNewIdentity

public void rebuildNewIdentity()
Rebuild a new identity the hard way - delete all of our old identity files, then reboot the router.


renderStatusHTML

public void renderStatusHTML(java.io.Writer out)
                      throws java.io.IOException
Throws:
java.io.IOException

addShutdownTask

public void addShutdownTask(java.lang.Runnable task)

shutdown

public void shutdown(int exitCode)

shutdownGracefully

public void shutdownGracefully()
Call this if we want the router to kill itself as soon as we aren't participating in any more tunnels (etc). This will not block and doesn't guarantee any particular time frame for shutting down. To shut the router down immediately, use shutdown(int). If you want to cancel the graceful shutdown (prior to actual shutdown ;), call cancelGracefulShutdown().


shutdownGracefully

public void shutdownGracefully(int exitCode)

cancelGracefulShutdown

public void cancelGracefulShutdown()
Cancel any prior request to shut the router down gracefully.


gracefulShutdownInProgress

public boolean gracefulShutdownInProgress()

getShutdownTimeRemaining

public long getShutdownTimeRemaining()
How long until the graceful shutdown will kill us?


saveConfig

public boolean saveConfig()
Save the current config options (returning true if save was successful, false otherwise)


restart

public void restart()

main

public static void main(java.lang.String[] args)
