Throws:

IOException

InterruptedException

stop

void stop()
   throws IOException

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

Throws:

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
 String privateKey)
                                                 throws 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:

IOException

removeHiddenService

void removeHiddenService(String onion)
                  throws IOException

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

Throws:

IOException

enableNetwork

void enableNetwork(boolean enable)
            throws IOException

Enables or disables the Tor process's network connection. The network connection is disabled by default.

Throws:

IOException

enableBridges

void enableBridges(List<String> bridges)
            throws IOException

Configures Tor to use the given list of bridges for connecting to the Tor network. Bridges are not used by default.

Each item in the list should be a bridge line in the same format that would be used in a torrc file (including the Bridge keyword).

Throws:

IOException

disableBridges

void disableBridges()
             throws IOException

Configures Tor not to use bridges for connecting to the Tor network. Bridges are not used by default.

Throws:
