Method Detail

start

void start()
    throws java.io.IOException,
           java.lang.InterruptedException

Starts the Tor process, but does not yet connect to the Tor Network. Call enableNetwork(boolean) for this.

This method must only be called once. To restart the Tor process, stop this wrapper instance and then create a new instance.

Throws:

java.io.IOException

java.lang.InterruptedException

stop

void stop()
   throws java.io.IOException

Tell the Tor process to stop and returns without waiting for the process to exit.

Throws:

java.io.IOException

setObserver

void setObserver(@Nullable
                 TorWrapper.Observer observer)

Sets an observer for observing the state of the wrapper, replacing any existing observer, or removes any existing observer if the argument is null.

getTorState

TorWrapper.TorState getTorState()

Returns the current state of the wrapper.

isTorRunning

boolean isTorRunning()

Returns true if the wrapper has been started and not yet stop() stopped.

publishHiddenService

TorWrapper.HiddenServiceProperties publishHiddenService(int localPort,
                                                        int remotePort,
                                                        @Nullable
                                                        java.lang.String privateKey)
                                                 throws java.io.IOException

Publishes an ephemeral hidden service.

Parameters:

localPort - The local port on which the service is listening.

remotePort - The port number that clients of the service will see.

privateKey - The private key of the hidden service, in the form returned by a previous call to this method, or null if a new service should be created.

Throws:

java.io.IOException

removeHiddenService

void removeHiddenService(java.lang.String onion)
                  throws java.io.IOException

Removes (unpublishes) an ephemeral hidden service that was created by calling publishHiddenService(int, int, String).

Throws:

java.io.IOException
